1. Technical Concept

1.1 Application

The Power Quality-Interface for low-, medium- and high-voltage networks PQI-DA

is the central component of a system, which executes all the measurement tasks

in electrical networks.

The PQI-DA can be used both as Power Quality-Interface according DIN EN 50160

and as measuring device for all physically defined measured variables in three-

phase systems.

The unit is mainly adapted for monitoring and recording certain supply qualities

or quality objectives between utility and customer and, furthermore to provide the

data for evaluation and storage.

Modern voltage-quality measurement devices operate according to IEC 61000-4-30.

This standard defines measuring methods in order to establish a comparable basis

for the user.

Devices from different manufacturers, operating according to this standard, have

to provide approximately the same measurement results.

The standard distinguishes between two classes of measurement devices.

Class A measurement devices are mainly used for contractual measurements in

customer-supplier relations, whereas class B measurement devices can be used

to determine statistical quality values. For measurements according to EN50160a class B device is sufficient.

For the following parameters PQI-DA fulfills the requirements of IEC 61000-4-30

for class A devices.

Parameter Class

• Accuracy of voltage measurement A

• Determination of time intervals A

• Marking of measured values at events A

• Harmonics, interharmonics A

• Frequency A

• Voltage asymmetry A

• Event recording A

• Time synchronization A (with DCF77 or GPS)

In addition, three different fault recorders can be used.

The oscilloscope recorder collects fault records consisting of 100 µs-sampling

values whose length (pre-event and post-event history) is freely selectable.

The r.m.s. recorder collects fault records consisting of r.m.s. values of half-period

values (10ms). The length of the fault record (pre-event and post-event history) isalso freely selectable.

Page 9: PQI-DA Operating Manual

8/12/2019 PQI-DA Operating Manual

http://slidepdf.com/reader/full/pqi-da-operating-manual 9/88

When exceeding a limiting value (harmonic or THD of a voltage), the harmonic

recorder registers the corresponding spectrum of all harmonics from 2nd to 50th

harmonic.

All fault records are triggered by a freely definable event. Phase-phase and phase-

earth events can be recorded simultaneously.

The signal-voltage-recorder registers a freely adjustable frequency (e.g. ripple

control frequency) over a period that can be selected.

Limit violations can be signalled via relays, if required.

On the input-side (U, I) the interface is available in different hardware-versions.

Current inputs are available for the measuring circuit (C20, C30) and for the pro-

tection circuit (C21, C31).

The following input characteristics can be selected:

• 4 voltage transformers for common power-quality applications (code C00)

• 8 voltage transformers for power-quality applications in double-busbar systems

(code C10)

• 4 voltage transformers and 4 current transformers for power quality and general

measuring tasks (code C20, C21, C30, C31)

Theoretically, up to 255 devices can be interlinked via the system bus (E-LAN).

Even connections to devices of the voltage regulator system REGSys™, the Pe-

terson-coil controller REG-DP, the earthfault detection system EORSys and the

collapse prediction system CPSys are possible.

Each device offers two RS 232 interfaces (COM1 and COM2) and two E-LAN

(Energy Local Area Network) interfaces.

Optional the PQI-DA can be equipped with an integrated TCP/IP-interface. In this

case COM 2 is not available.

Possible firmware-updates can be easily made via a pushbutton, prevented against

unintentional touch.

2. Application

2.1 PQI-DA as a Recorder (Fault Recorder)

Fault records are stored in the recorders A, B and C each time a fault occurs.

Trigger condition is either the falling below or exceeding a voltage limit or an exter-

nal trigger signal. When the system is triggered, the pre-event and the post-event

history of the voltage and current shape is recorded. You can choose between

three different recorders.

2.1.1 Recorder A

Recorder A stores fault records of the events before and after the fault occurs using,

for example, 2048 sampling values for each of the 8 measurement channels (1024

before, 1024 after). The measurement value acquired in each channel is dependenton the configuration of the transformer and the version of the device.

Recorder A

8 voltages are sampled if 8 voltage inputs are used. If the measurement task

requires four voltage inputs and four current inputs, then four voltages and four

currents are measured accordingly.

8 simultaneously sampled momentary values are available every 100 µs, based

on a sampling frequency of 10.24 kHz. These can be used to reconstruct a

“fingerprint” of a particular event.

The number of events, the total recording time and the position of the trigger pointwithin the time slice can all be individually specified.

PQI-DA Operating Manual 11

PQI-DA

Page 12: PQI-DA Operating Manual

8/12/2019 PQI-DA Operating Manual

http://slidepdf.com/reader/full/pqi-da-operating-manual 12/88

The selection of the trigger point specifies how many periods (seconds) of infor-

mation before the fault and how many periods of information after the fault should

be recorded per event.

Example: The total length of the record is specified as 2000 sampling points

(approximately 200 ms). This represents 10 periods for a network frequency of

50 Hz. If the pre-trigger is set to 1000, the information before the event and the

information after the event are both 5 periods, or 100 ms, long.

The total number of permissible trigger events must be chosen carefully since

records stored with recorder A require a very large amount of memory.

If the specified number of events is exceeded, either the oldest events will be

overwritten or no further records will be stored.

The desired behaviour can be chosen using Win PQ. The trigger conditions which cause recorder A to be used can also be freely spe-

cified, i.e. they are not constrained to the limit values specified in EN 50160.

The trigger condition is created by linking selected events together with OR con-

ditions.

The record shows the single-pole earth fault, which changes to a 2-pole earth

fault a short time later.

This could be caused by the events described in the following account.

A mistake occurred in the cable duct: a hydraulic cutter was used to cut a cablewhich was still connected to a voltage supply instead of one that was discon-

nected.

As the edge of the blade touched the first phase, it caused a single-pole earth

fault and an increase in the neutral earth voltage. A short time later, two phases

were short-circuited by the blade (phase-phase fault).

The subsequent progress of the fault process is explained in conjunction with

recorder B.

2.1.2 Recorder B

Recorder B stores fault records for the 1/2-period r.m.s. (root mean square) values

of phase and delta voltages. A record consists of a specifiable number of 1/2-

period r.m.s. values. Thus 10-ms values are recorded if the operating frequency

is 50 Hz.

The trigger condition is created by linking selected events together with OR con-

ditions.

The number of events, the total recording time and the position of the trigger pointwithin the time slice can all be individually specified.

The selection of the trigger point specifies how many half-period values (10-ms

values) should be recorded before and after the fault per event.

Recorder B

Example:

The total length of the record is specified as 500 10-ms values (approximately 5 s).

If the pre-trigger is set to 250, the information before the event and the information

after the event are both approximately 2.5 s long.

The total number of permissible trigger events must be chosen carefully. Records

stored with recorder B require a large amount of memory.

If the specified number of events is exceeded, either the oldest events will be

overwritten or no further records will be stored.

The desired behaviour can be selected using Win PQ.

The trigger conditions which cause recorder B to be used can be freely specified,i.e. they are not constrained to the limit values specified in EN 50160.

The record (see page 13) shows the fault illustrated on page 10 with a reduced

resolution (10-ms r.m.s. value).

Due to the resolution it is no longer possible to recognise the path to the fault, i.e.

the route from a single-pole to a 2-pole fault. However, one can see the effect of

the overcurrent relay which disconnected the faulty cable from the busbar after

approximately 400 ms.

2.1.3 Recorder C

Recorder C stores the corresponding harmonic spectrum (10-minute harmonic

values) of a voltage if a harmonic limit or the THD (Total Harmonic Distortion,10-minute value) of the voltage is exceeded.

The trigger condition is created by linking selected events together with OR con-

ditions.

Recorder C

The comparison shows the three recorders A, B and C again as they are triggered

by a dip in the voltage between time t0-1 and time t0.

http://slidepdf.com/reader/full/pqi-da-operating-manual 15/88

After the zero point (t0 ), recorders A and B store information regarding the time

period before and after the event, whereas recorder C only stores the 10-minute

harmonics values of the information before the event.

2.1.4 Events

By definition, an “event” occurs every time a measurement quantity exceeds the

threshold value specified in EN 50160 or any other predefined value

Each event is stored in the event memory along with the start and stop time.

Events which permanently exceed the threshold value are re-triggered at the end

of every 10-minute or 2-hour interval.

On the other hand, events which permanently exceed the threshold value are not

re-triggered at the end of every 10-ms interval or at the end of 1/2, 10, 12, 150

or 180-period values.

In these cases, only a stop event is recorded when the threshold value is no longer

exceeded.

To create time sums in these cases, the duration of the event is calculated from

the difference between the start and the stop time of the event, and is then stored

in the event memory.

REG-DM, PAN-D, REG-DP, MMU-D, EOR-D etc.) from A. Eberle GmbH&Co KG to create a measurement-, registration- and/or control-system.

The individual devices are connected to each other via the E-LAN system bus, and

up to 255 different devices can communicate with each other via one E-LAN.

If multiple transformers feed energy into a network in a transformer station and

each is equipped with a PQI-DA, the partial power of the individual transformers

can also be measured by the corresponding PQI-DAs. They transmit the partial

power to a particular PQI-DA via E-LAN, which then outputs the total power using

a virtual measurement channel.

Furthermore, freely programmable binary inputs can be linked with measurementvalues or limit values, and also output as a binary signal.

5. Serial interfaces

5.1 RS232 interfaces

Each PQI-DA has two RS 232 interfaces referred to as COM 1 and COM 2.

COM 1 can be used as a parameterisation and programming interface via a 9-pole

SUB-D plug.

COM 2 can be wired via a plug-in terminal block.

If option T1 (COM server / TCP/IP) is selected, an RJ 45 connection is available

instead of COM 2.

Connection elementsCOM 1 Pin strip, Sub Min D

Handshake RTS / CTS or X ON / X OFF

5.2 TCP/IP

The TCP/IP or COM server interface is galvanically isolated from all other electrical

circuits.

Communication via this interface is possible with a baud rate of 100 MBaud.Parameterisation of the connection (IP address etc.) is carried out using the WinPQ

parameterisation software.

5.3 RS485 Interfaces

Each PQI-DA is equipped with a double E-LAN interface as standard. It pro-

vides the bus connection to PQI-DAs, REG-D voltage regulators, REG-DP

Petersen coil regulators, or an EORSys earth fault locating system.

5.4 E-LAN (Energy - Local Area Network)

5.4.1 Features

• 255 bus stations can be addressed

• Multimaster structure

• Integrated repeater function

• Open ring, bus or combination of bus and ring possible

• Log based on SDLC/HDLC framework

• Transfer rates of 62.5 or 125 kbit/s

• Telegram length 10 to 30 Bytes

• Average throughput approx. 100 telegrams / s

5.4.2 Configuration Information

The E-LAN (Energy- Local- A rea- Network)) is a powerful bus which is used to

communicate with all the other bus devices, and which can be operated as either

a 2-wire or a 4-wire bus.

The bus controller can store up to 255 addresses. This means that theoretically

up to 255 A. Eberle GmbH & Co. KG devices can be operated by one E-LAN,

and they can all be read and parameterised using a single COM 1 or COM 2

(RS232) interface.

The transfer speed ranges from 15.6 to 375 kBaud.

It is possible to use either a 2-wire and 4-wire line-to-line connection, or to ope-

rate up to 32 devices in parallel using a dedicated 2-wire line like a standard bus

connection.

Mixtures of the two topologies are possible, as is the conversion to other bus

protocols and other physical media (LWL connection, coaxial cable, etc.).

The line-to-line topology has an E-LAN characteristic which is particularly useful

for distributed installed devices.

Two RS485 devices can be separated by up to 1.2 km according to the specifi-

cation of the RS485 driver.

However, since all PQI-DA, like all other bus components, is equipped with a double

interface (E-LAN left and E-LAN right), each device acts as a repeater, meaning

the distance to be bridged can be increased by a further 1.2 km.

Figure 14 shows a configuration in which four PQI-DAs, with addresses <A> to

<D>, are operating on a dedicated 2-wire line using the standard bus technology.

The distance between these four devices may not exceed 1.2 km.

A second bus line is opened from address <B>. In this example, it leads to twobus stations – a REG-D voltage regulator (address <E>) and a Peterson coil re-

gulator (address <F>).

PQI-DA Operating Manual 29

PQI-DA

Page 30: PQI-DA Operating Manual

8/12/2019 PQI-DA Operating Manual

http://slidepdf.com/reader/full/pqi-da-operating-manual 30/88

In this example, an EOR-D is connected to the right hand E-LAN interface of the

PQI-DA with address <D> using a 4-wire connection.

The question “Which device should be connected to the right interface, and which

to the left interface?” is easily answered: both are acceptable. The system can

detect which sort of device is connected to which interface (left or right) and enters

the corresponding bus station (address, type of device, type of connection) into

its own bus index.

Therefore, the bus type doesn’t have to be taken into consideration when planning

an E-LAN. However, one must ensure that each E-LAN component has a unique

address (A...A9, B...B9, C...C9.....Z...Z4) and that the transfer speed and bus

topology are identical between two devices that are connected with each other.

Furthermore, one must ensure that if a two-wire connection is used, the first and

last bus connection are terminated with a resistance as this prevents reflectionsfrom occurring. The resistances are available in every device (as hardware) and

can be activated or deactivated using WinPQ.

E-LAN connections that are not used should either be terminated or operated in

the 4-wire mode.

The PQI-DA has an accurate quartz real time clock (RTC), which continues to run

even if the auxiliary voltage is interrupted. The synchronisation of multiple devicesis achieved by linking the PQI-DAs via the so-called time synchronisation bus

(RS 232) and/or E-LAN.

A device defined as the time master cyclically transmits its local time via E-LAN

to all the other PQI-DAs. The master also sends additional pulses each second

via the time synchronisation bus to achieve sub-second accuracy. Thus, the real

time clock of each synchronised PQI-DA will exactly match that of the master

PQI-DA.

If the master PQI-DA is synchronised by connecting a radio time signal (e.g. the

MSF signal in Great Britain), this signal is also applied to all the PQI-DAs it syn-

chronises.

Multiple PQI-DAs can also be synchronised by assigning a radio time signal receiver

or GPS receiver to each PQI-DA.

5.6 Parameterisation

The PQI-DA Power Quality Interface & Disturbance Recorder can be connected to

the E-LAN just like all other REGSys devices. A PC is used for the parameterisationand the management of the synchronisation as well as to display the measurement

data of the networked devices. It is connected to one or more PQI-DAs using

the COM interface. REG-L commands are used for communication and both the

WinPQ and the ParaPQ programs can be utilised.

The data management of the system encompasses both the internal and external

management of the measurement and parameterisation data (within the device

and using a PC respectively). The user can only access the settings, statuses

and measurement data of the devices by using a PC (serial interface) since the

PQI-DAs do not contain an operator interface.

However, the units do not require any external computer to carry out the measure-ments.

Each PQI-DA can record measurement data for a certain amount of time, after

which the information must be transferred to a PC (database) as offline data.

A selection of online data can also be transferred to the PC, either continuously

or all at once. The selection is not affected by the configuration of the recording of

the measurement data. Both online and offline data can be displayed, but in order

to use the device memory and transfer capacity efficiently, the user must specify

which of the measurement quantities should be permanently displayed.

5.6.1 Parameterising the Device

The PQI-DA offers a wide range of measurement possibilities, and not all measure-

ment quantities are required all the time.

However, the parameterisation principle is the same for all of them.

The following parameterisation steps are required:

5.6.1.1 Transformer configuration

The PQI-DA offers complete freedom with regard to configuring the transformer.

Voltage transformers and current transformers can be parameterised indepen-

dently of each other, ensuring that (almost) every type of measuring circuit can

be achieved using PQI-DAs.

5.6.1.2 Measurement range

PQI-DAs are particularly suited for use in medium and high voltage networks.However, their use in low voltage networks (230 V → custom value) is also pos-

sible without restrictions.

8/12/2019 PQI-DA Operating Manual

http://slidepdf.com/reader/full/pqi-da-operating-manual 35/88

5.6.1.3 Network frequency

The acceptable frequency range for fundamental current and voltage oscillations

is 45...65Hz.

The WinPQ software can be used to configure the triggering options of an event

or fault record for the individual measurement quantities.

5.6.1.4 System time

The system time can be entered into the PQI-DA or controlled by a radio time

signal (real time clock), e.g. in Great Britain, the MSF signal.

A “time drift” of up to 12 minutes per year may occur if a radio clock synchroni-

sation system is not used.

5.6.1.5 Definition of measurement channels for interval data and

event-triggered measurement data

Specific measurement quantities that are appropriate to the type of task being

carried out can be selected and assigned to a measurement channel. Over 3,000

measurement quantities are available.

5.6.1.6 Configuration of the recording of the measurement data

The available memory can be divided according to the type of task being carried

out. If records or events are of particular interest, a significant part of the memory

can be used for these items.

5.7 Hardware-orientated device versions

The flexibility of the system, i.e. precisely matching specific requirements, canalso be achieved using the hardware characteristics of the input and output con-

figuration.

Table 1 shows the different possibilities.

6. Characteristics of the Voltage Supply

The trend to permanently monitor the quality of the network is constantly increasing.

This is, on the one hand, due to the original specification of the task – the desireto have fixed monitoring – and, on the other, due to the standards and regulations

that have arisen as a result of this desire.

Previously, a transportable device was installed in the system after a fault occurred.

The time t0 was deduced from the measurement between t1 and t2. If no fault

was detected between t1 and t2, one concluded that a fault also did not occur

between time t0 and t1.

This argument is both false and unscientific.

Due to this, EN 50160 defined a sequence of measurement intervals, which require

continuous measurement.

EN 50160 specifies average values that span 10 minutes, days, weeks and up to

a year. Measurements that last months or years can obviously only be achieved

using permanently installed devices.

The range of values and evaluation parameters for low voltage and medium voltage

networks are listed in the following tables.

6.1. Limit Values Specified in EN 50160

DIN EN 50160 “Voltage characteristics of electricity supplied by public distributionsystems”: 2008 generally leaves the precise specification of limits to be jointly

agreed upon by the energy supplier / distributor and the consumer.

This is to be expected, since this area is not uniform throughout Europe.

A feature that is essential for one recipient could have a much lower priority for a

different recipient.

Therefore, it is not only sensible, but also essential, that the voltage quality that

is to be supplied is defined in the negotiations between the energy suppliers and

the consumers.

Table 1 summarises the quality parameters specified in EN 50160 that are most

frequently used.

An example based on the row in Table 1 labelled “Random long interruptions to

the supply (>3 minutes )” (highlighted in grey) shows that the standard is only

applicable via negotiations between the energy supplier and the recipient.

For example, the Standard permits 10 to 50 interruptions of random length to the

voltage supply per year that may each last > 3 minutes.

There are 8760 hours in a year, and if one defines a voltage interruption as 175.2

hours (permissible since 175.2 hours > 3 minutes), it would be possible to notsupply any energy for an entire year and still remain within the framework of EN

50160 (8760 hours = 50 interruptions * 175.2 hours).

This extreme example shows that the regulation only specifies the framework,

within which an individual voltage quality can be defined.

The PQI-DA Power Quality Interface & Disturbance Recorder measures all the

quality parameters and enables the user to define his/her own limit values.

7. Measurement Circuits

Transformer Configuration

In general:

If the neutral earth voltage UNE is not available, terminal “N” must be con-

nected to terminal “E”.

The choice of the type of connection is made via WinPQ.

Voltage transformer configuration and current transformer configuration can

be set independently of each other and therefore they can be adjusted to

any network situation.

Information:WinPQ offers a button to carry out this procedure as simple as possible.

7.2 Current Transformer Connections

Each PQI-DA Power Quality Interface & Disturbance Recorder has four current

inputs. In general, inputs I1 to I3 can be used to measure the line currents. The fourth current can be used as a sum current or as a neutral conductor current

input.

For sum current measurements, it is irrelevant if the sum current is created using

a sum current transformer (core balance transformer) or a Holm-Green circuit.

Only two currents are required in an Aron circuit, because in “healthy” three-

conductor networks the third current can be calculated if the other two currents

are already known (a healthy network is one in which the vector sum of all three

currents is zero).

Normally, an Aron circuit is applied in such a way that the currents in L1 and L3are measured and are then used to calculate L2.

The PQI-DA is not limited in this case either, since the appropriate input configurati-

on is prepared regardless of which phases have a current transformer available.

Only one current transformer needs to be connected in equally loaded networks.

In this case the PQI-DA transmits the total power, by multiplying the phase power

by 3 (the three individual powers are the same if the network is equally loaded).

The appropriate input configuration is prepared in this case too, regardless of

which phase contains the current transformer.

8. Management of Process Data within the Device

When the PQI-DA is operating, it generates a large amount of continuous and

event-triggered data, of which only a certain proportion can be measured andsaved within a limited time period. The length of the saving process is dependent

on the amount to be saved as well as on how often the data is transferred to the

PC database.

The selection of the data, as well as the method of displaying it, must be configu-

rable so that the device memory and transfer capacity resources can be used

as flexibly and efficiently as possible. Therefore, all the configuration parameters

are readable and stored in the device so that the process data are uniquely iden-

tifiable at all times when accessed using a PC.

8.1 Classification of the Data The transferred data can be assigned to one of the following categories:

Settings (parameters)

10/12* periods (0.2 s) – process data

150/180* periods (3 s) – process data

10-minute process data

2-hour process data

Day-long process data

Event data

Fault records* 10/12 and 150/180 correspond to 50 Hz and 60 Hz networks and specify the

number of measured periods.

Example:

One period in a 50 Hz network lasts 0.02 s. Therefore, an integration over 150

periods produces a total measurement time of 3 s. On the other hand, 180 periods

are required in 60 Hz networks to (approximately) achieve a 3-second average

value, since each period lasts 16.666 ms.

The measurement times differ from 3 s if the frequencies fluctuate by a large

amount.Example:

If the frequency is 49 Hz, the measurement time is not 3 seconds, but 150 x

1/49Hz =3.06 seconds.

A data class can contain different types of measurement values:

The 10-minute and day-long process data consist of both average values and

extreme values, whereas the fault records contain µs sampling values, ½-period

values and spectra.

10-minute process data: Average values, extreme values

Day-long process data: Average values, extreme values

Fault records: Sampling value, ½-period values, spectra

Event value = measurement value when comparing limit values.

Start / stop events:

Start and stop events are created at the beginning and end of a limit va-

lue violation respectively, and at the end of a measuring period if it lasts

<10 minutes. They are not repeated during a continuous limit value violation.

Event value (start event) = measurement value when comparing limit values.

Limit value (stop event) = extreme value since start event, i.e.maximum value for the maximum limit value,

minimum value for the minimum limit value.

9. Definition of the Measurement Quantities

A three-phase current contains several different measurement quantities which in

the past were indicated by different designations and/or indices. This is particularly clear in the designation of the neutral earth voltage which,

depending on mood and operating version, was referred to as En voltage, Uo

voltage, Uv voltage or even as E or N voltage. Therefore, Figure 17 is shown below

at the beginning of the explanation of the measurement quantities to ensure an

unambiguous and consistent terminology.

It illustrates the basic quantities for measurements in three-phase current sys-

tems. The designations are based upon the terminology specified in DIN 40110-2

“Quantities used in alternating current theory - Part 2: Multi-line circuits”.

Figure 17:

9.1 Sampling, Synchronisation

The sampling frequency is generated via synchronisation with one of the 3 input

voltage frequencies (reference channel). The synchronisation cycle spans 10 pe-riods for 50 Hz networks and 12 periods for 60 Hz networks. Thus the nominal

cycle time is:

msT SN

200=

The synchronisation frequency can fluctuate by up to ± 10% of the nominal value

(i.e. 45 Hz ... 55 Hz and 54 Hz ... 66 Hz respectively).

All input signals are sampled simultaneously. The number of samples per input

signal (current, voltage) and synchronisation cycle is:

2048211 == M

Thus, for a cycle time TS, the sampling frequency is

S

S T

M f =

The nominal sampling frequency for the corresponding frequency of the nominal

cycle time is therefore:

Hz f SN 10240=

Sampling Frequency Synchronisation

Signal processing is always based on a fixed number of sampling values, which

in turn depend on the type of measurement quantity to be calculated. The length

of the associated measurement interval must correspond to a whole number of

periods of the present network frequency in order to prevent beats occurring in the

measurement quantities (“leakage effect”). To achieve this, the sampling frequency

constantly tracks the network frequency so that they have a fixed relationship. Thereference quantity for this is the frequency of the voltage at the reference voltage

input. If the reference input voltage is interrupted for < 10 s, the last valid sampling

frequency is used. The nominal value is used if the interruption lasts for > 10 s.

The A/D transformer has a 24 bit resolution, including the (plus-minus) signs.

The r.m.s. width of the measurement band is 2.5 kHz.

9.2.2 R.M.S. Voltage Values

The sampling values of all the voltages are recorded continuously and without

overlapping when calculating the r.m.s. (root mean square) value.

9.2.2.1 Half-period r.m.s. voltage values

The original signal is represented by a step function. The height of the step is the

present value of the ADC and the width of the step is the measurement interval.

First, the half-period r.m.s. voltage values are calculated for continuous, half-pe-

riod-long, time slices. The sampling is not synchronised with the time slices and

this results in beats (flicker) occurring. This can be minimised by including the

corresponding weighting factors of the combined sampling values of consecutive

time slices in the calculation of both r.m.s. values. The resulting r.m.s. value is then

used as the input value for the flicker algorithm.

This results in 512 (256) sampling points or 5 (3) r.m.s. values per period for 50

The average of two consecutive r.m.s. values that is calculated every half-period

is known as the average half-period r.m.s. value.

It is used as a trigger quantity for start / stop events and is also a quantity stored

by recorder B.

Please also refer to: EN 61000-4-30:2008

The direct Fourier transform (DFT) spectra of all the phase voltages and input

currents are calculated from the 2048 sampling values of each input quantity as

10/12-period values per fast Fourier transform (FFT) algorithm. The spectra of the

linked quantities are calculated from the spectra of the measured quantities.

The spectral r.m.s. values for measurement quantities which have to be deduced

(since they are not otherwise available) are treated in the same way as the r.m.s.

10. Commissioning

10.1 Safety Information

Before you begin to use the device, you should be aware of some of the dangers

that may occur if the device is used improperly.

The device belongs to safety class I. Please connect the device’s protective

earth conductor to your system’s earthing system before the device is con-

nected to a voltage supply.

The device may not be used to carry out measurements on circuits that contain

corona discharges.

The device must be removed from the network immediately if it is determined

that the device can no longer be operated safely due to a mechanical or elec-trical fault.

Please note: if the Power Quality Interface & Disturbance Recorder is installed

in a housing, the secondary circuits of the current transformer must be short-

circuited before the terminal connections of the current transformer are removed

from the device. Devices in 19” enclosures are protected against short circuits

via a device built in to the terminal block. The modules can be plugged in and

out at will without having to short circuit the current transformer(s) first.

Please note that there is a danger to life wherever a voltage with an amplitude

> 30 V r.m.s. is present.

10.2 Procedure

Preparation:

Please look at the nameplate and confirm that the supplied device conforms to

your requirements.

Is the voltage supply correct?

Information: Changes to the voltage supply range can only be carried out in

our factory.

Are the measurement quantities for the input current (1A/5A) of the applica-

tion correct?

Are the voltage and current connected correctly?

Check the connection using the phase powers. All the powers must have

the same sign (plus or minus). It should be a plus “+” if energy is being

drawn, and minus “-” if energy is being supplied.

If the polarities are not the same, the error is usually due to the current con-

nections being incorrect.

Part of the WinPQ program is specifically designed for the parameterisation and

programming of the analogue outputs, binary inputs and the LEDs.

11. Applications

11.1 Application-Specific Programming

Programs for specific tasks can either be written yourself using REG-L or can be

requested from our headquarters.

An example of an application-specific program is shown in section 2.3.

12. Updating the Firmware

The PQI-DA must be disconnected from the power supply before updating the

firmware.

The reset button must remain pressed in when the voltage supply is connected.

The status LED changes colour to indicate that the device is in the update

mode.

If it is red, it means the device is ready to be updated.

The firmware update must be carried out directly on the device itself, and requires

the following steps:

Establish a physical connection between the PQI-D and the zero modem

cable.

The program “COMM.EXE” can be found in the “Firmware” folder, which is

located in the directory containing the WinPQ program. To upload the new

firmware, select a transfer speed of 115 baud and “RTS/CTS” for the hard-

ware protocol.

Then switch the station into the firmware upload mode (by pressing the

reset button for at least 5 seconds), and the status LED changes to red.

Select “Terminal / Send firmware with reset” in the menu of the COMM.EXE

program.

The familiar Windows “Open file” dialogue is displayed. Use this to open the

correct firmware file (e.g. PQI-UU.MOT). The data transfer begins immedia-

tely and the progress of the upload can be seen in the program’s status bar.

Verify the version number once the upload is complete (3 to 5 minutes).

When the “VER” command is issued, the system replies (for example):

“PQI-DA: Version 2.0.10 from 23.07.04”

Finally enter “SYSRESET=590” and the station will restart. The status LED

will light up again after approximately 8 seconds.

The stations parameterisation can then also be remotely restored using the “PQPa-ra” section of the program.

13. Scope of Delivery

PQI-D corresponding to the characteristics specification

Operating manual

Supplement

14. Storage Information

The devices should be stored in clean, dry rooms. The devices and their respective

replacement modules can be stored between -25 °C and +65 °C.

The relative humidity must not cause the formation of either condensation or

ice.

We recommend that the storage temperature remains between +0 °C to +55 °C

to ensure that the built-in electrolytic capacitor does not age prematurely.

We also recommend that the device be connected to an auxiliary voltage every

two years to reform the electrolytic capacitors. This procedure should also be

carried out before the device is put into operation. Under extreme climatic condi-

tions (tropics), this also simultaneously ensures “pre-heating” and helps to avoid

the formation of condensation.

The device should be stored in the service room for at least two hours prior to

being connected to the voltage for the first time so that it can become accus-

tomed to the ambient temperature there and to avoid the formation of moisture

and condensation.

15. Guarantee

The guarantee is valid for three years from the date of delivery.
