DC diagnostic insulation resistance testing

Regular insulation resistance testing is one of the most cost effective, non-destructive methods of identifying aging in electrical equipment. Over 60% of equipment failures are attributed to insulation breakdown. Diagnostic DC testing is probably the easiest and most convenient method of achieving this due to the small size and weight of the equipment.

High Performancewith its 8 ma noise immunity and 4 user-selectable filters, the s1 series is able to provide stable measurements even in noisy 765 kV substations. the high 6 ma output current enables quick charging of high capacitance apparatus and ensures that the test voltage can be maintained even with high surface leakage.By extending the maximum test voltage to 15 kV, the s1-1568 allows compliance with Neta mts-1997 and Neta ats 2007 for medium-voltage motors, and IeC 60229 2007 for electric cables with a special protective function. these are the only instruments on the market capable of providing a 5% measurement accuracy up to 100 gΩ as specified by the standards.

Always Safethe s1-series can be remotely operated via the isolated usB interface to provide additional operator safety in high energy locations where induced potential hazards might be present. all test terminals on the 5 and 10 kV units have a CatIV 600 V safety rating up to 3000 m in altitude while the 15 kV units are CatIV 1000 V safety rated up to 4000 m.

Easy Testingall units are preconfigured with diagnostic tests including Polarization Index (PI), Dielectric absorption ratio (Dar), Dielectric Discharge (DD), stepped Voltage (sV) and ramp test. this allows even first time users to quickly become productive with the instrument. Both digital and analog readings are displayed on a large, backlit lCD display and the user can easily toggle between different tests with the intuitive rotary switch.

Fast Chargingthe fast charge li-ion battery can be fully charged in 2 hours and the units can be powered through an aC source even when the battery is flat. the battery is also designed to be user-replaceable without voiding calibration.

Pinpointing system

PD LOC

the PD loC system solves the problem of pinpointing for mixed cables (XlPe/PIlC) and for PD in joints of single core cables. In the field the exact location of the joints is not generally known, and these joints cannot be localized using audio frequency methods. this system has an impulse transmitter that uses an inductive coupler to inject a signal into the cable. the receiver and evaluating unit consists of an input amplifier for processing the signal and a control unit in a single case. the visualization of the distance system’s transmitter location is performed by using a tDr in a separate menu, by means of an additional PD software function.

Partial discharge detection and mapping

Partial discharge detection and mapping are powerful techniques to diagnose the condition of a cable network and to predict where faults are likely to occur. By allowing the replacement of damaged cable in advance of failure, it prevents power users losing supply unexpectedly. These compact systems measure partial discharge at points along a cable using the damped AC method (DAC).

Partial discharge detector

TE PDS

this provides an inductive and capacitive sensor for quality assessment by detecting partial discharge in joints and terminations of HV insulated cables.

TDS NT series

the tDs Nt consists of a multifunctional, compact voltage source and a PD detector. the tDs Nt can be used to test cables with a powerful VlF-Cr voltage as per international standards (IeC, Ieee). In addition, using the PDs 60 PD detector a PD diagnosis can be performed. alternatively, the tDs Nt can be used for a PD diagnosis with the proven damped aC test voltage (DaC).

the innovative evaluation algorithm enables reliable detection and precise location of partial discharges (PD mapping) while the actual measurement is taking place. the time consuming, post processing of data is not needed and direct measures can be planned based on the outcome of the data. the tDs Nt is available in four different models, two 40 kV and two 60 kV versions. the set consists of a power source, pd detector, pd calibrator, laptop, sw license and all cables.

Medium voltage cable phase identifier

PIL 8

the PIl8 uses three pairs of transceiver clamps connected without any leads, one to each of the short circuited phases. the transceiver clamps do not require a power supply. at the other end of the cable an audio frequency current is injected into the cable by means of a battery operated generator/receiver. this induces a voltage in the transceiver clamps which is rectified and stored in a capacitor. when sufficiently charged the clamp transmits a coded signal to the receiver indicating the designated phase to which the pairs of clamps has been connected.

Acoustic and electromagnetic surge wave receiver

digiPHONE+

this instrument sets the standard by integrating audio and electro-magnetic functionality into one simple to understand unit. Combining two new technologies for efficient noise suppression, it offers exceptional acoustic performance which

filters the fault noise. this means it is possible to lower the surge energy and find faults in noisy environments. the operator’s hearing is protected by auto proximity mute, turning off the head set as a hand approaches the sensor handle and turning it on again once mechanical oscillations have ceased, and limiting the earphone output to 84 db(a).

Cable tracing is simplified using the left right indicator keeping the sensor over the cable while the compass indicates the direction to the fault and the color display shows the distance to the fault.

Cable locating and fault pinpointing

These are used in conjunction with a surge generator or sheath fault locator pulsed energy source to find the exact location of a fault.

the PIl 8 meets the requirement of eN50110-1 (VDe 0105 part 1), because its application eliminates the need to disconnect the short circuiting and earthing circuit. after installation of the three pairs of clamps, the switchgear chamber can be closed, greatly enhancing safety.

High current, low resistance testing

Safer and Faster Testing with DualGround™Dualground™ is megger’s groundbreaking technology that enables a safer and faster workflow because both sides of the circuit breaker remain grounded throughout the test.

Dynamic Capacitance Measurementmegger test sets with Dualground™ technology uses dynamic capacitance measurement (DCm) to measure contact timing on circuit breakers with both sides grounded. the results are identical to those achieved with conventional contact timing methods. this makes it possible to test circuit breakers without removing jumpers and bus-bar connections, opening up a wide range of applications in gas insulated substation, generator and transformer breaker diagnostic testing.

Why is it safer?Conventional timing requires at least one side of the circuit breaker to be ungrounded to allow the instrument to sense the change in contact status. live high voltage conductors will induce currents in all parallel conductors due to capacitive coupling. In a disconnected circuit breaker with one side connected to earth and both disconnectors open, this current can reach double digit ma values which are lethal for humans.

the DCm technique uses high frequency to achieve resonance in the test circuit. the resonance frequency varies when the circuit breaker changes state, and this is how a change from open to closed (and vice versa) is detected. this also means that the technique is completely immune to the effects of 50 or 60 Hz interference.

using DCm we can obtain reliable measurements with both sides of the circuit breaker grounded, thus never exposing personnel to any induced currents.

Testing with DualGround™

testing is much safer using the DCm module and Dualground.

with only one side grounded the induced current can reach values high enough to be harmful or lethal for humans.

the CB-832 is a self-contained test set that incorporates a variable high-current output and appropriate control circuitry and instrumentation for testing thermal, magnetic or solid-state motor overload relays; molded-case circuit breakers; and ground-fault trip devices.

Circuit breaker and overcurrent relay tester

MS-2A

ms-2a is capable of testing the time-delay characteristics of overcurrent relays, motor overload relays and moulded-case circuit breakers, rated up to 125 a, when following the recommended test procedure for testing the time delay of these devices at three times their rating.

Higher currents are available for the short durations required to test an instantaneous trip element. For example, the test set will provide a maximum short duration output of 750 amperes through a typical, 125 a, moulded-case circuit breaker.

the DDa-3000 and DDa-6000 series are designed specifically to test low-voltage power and molded-case circuit breakers equipped with thermal, magnetic or solid-state trip devices. the units are fully compliant with Nema aB-4 test guidelines.

tests are performed by simulating an overload or fault condition. each test set is an integrated test system that provides a variable, high-current output. the test sets incorporate all control circuitry and instrumentation necessary to test direct-acting circuit breakers accurately, efficiently and safely.

The principle behind primary current injection testing is simple – a test current is injected into the high current side of the system to determine how various system components function at this particular level of current. The test current used has to be similar in magnitude to the current expected during continuous or instantaneous operation of the electrical apparatus so that operating conditions are accurately simulated. Primary current injection is a versatile technique that can be applied to test the operation of circuit breakers, automatic reclosers and sectionalizers, the ratio and polarity on current transformers, and the integrity of ground grids and other safety grounding devices.

Protective relays in the electrical power system provide protection against overloads, faults, abnormal conditions, etc. Like any complex device, relays deteriorate over time. Electromechanical relays may malfunction due to aging of mechanical components, and even solid state and microprocessor based relays with no moving parts may experience electronic circuitry failure or software/firmware issues. NETA Maintenance and Testing standards recommend routine testing of your relays to ensure they function correctly when needed. Proper testing and maintenance of protective relays safeguards the integrity of the protection scheme, prevents nuisance tripping and minimizes damage to equipment when faults do occur.

Transformer testing

Transformers are one of the most critical and expensive assets in a substation. If a large transformer fails it will be a major problem for the asset owner. It will be expensive to repair or replace and there may not be a replacement of the required type available on short notice. Extending transformer life and predicting failure is becoming increasingly important to asset owners and managers.

Insulation diagnostic analyzers

IDAX series

IDaX 300 series uses frequency domain spectroscopy techniques and state-of-the-art software to make a transformer

moisture assessment in less than 18 minutes. FDs is a reliable and accurate method for assessment of the condition of the insulating components of transformers and bushings. It measures capacitances and tan delta (or power factor) of the insulation between the transformer windings at multiple frequencies and plots the resultant curve. Comparing this measured curve with a modelled curve allows estimation of the moisture content. the IDaX 350 incorporates an on-board PC for results analysis and reporting within the enclosure.

adding the VaX020 to the IDaX300 expands the test voltage range from 200 V to 2 kV. this improves IDaX’s test performance in terms of accuracy in environments with extremely high interference such as HVDC substations.

12 kV tan delta power factor test set

DELTA4000 series tough yet light, and designed to work reliably in high-interference areas like substation switchyards, megger’s Delta4000 series diagnostic insulation systems offer time saving, fully automatic power factor/tan delta measurement and tip-up testing. also provided are facilities for full manual control –including the ability to vary the applied voltage up to 12 kV during testing – to cater for special testing requirements.

accurate and dependable temperature correction based on the actual condition of the test object, can be applied to results using a novel technique, which works with data acquired from a separate dynamic frequency response (DFr) test. automatic detection of non-linear response, which suggests the need for further tip-up testing and which is often a useful indicator of incipient insulation problems, is also provided. Despite their small size and low weight, megger’s Delta4000 series test sets offer comprehensive facilities for assessing the condition of electrical insulation in all types of high voltage equipment including transformers, bushings, circuit breakers, cables, lightning arrestors and rotating machinery. they also measure the excitation current of transformer windings.

the test sets generate their own test voltage, which is independent of supply quality. a further benefit of this approach is that it allows the test voltage to be varied in frequency from 1 Hz to 500 Hz, making the instruments even more versatile. there is the option of using an on-board computer or an external computer to control the Delta4000.

For multiple frequency tan delta measurement as used on generators and transformers, see the IDaX on page 35.


Leakage reactance tester

Portable current transformer tester

MLR10

BA185

Sweep frequency response analyzers

FRAX series sFra is a method for assessing whether or not a transformer has been subject to mechanical damage, for example when moved or from a lightning strike. FraX and its software allows repeatable fingerprinting of transformers so that a scan can be run whenever it experiences a traumatic event such as transportation, severe fault or overhaul, allowing it to go back on line faster. Ideally a transformer is fingerprinted at birth, but performing sFra on older transformers is also advisable so any future problems can be diagnosed. Compatible with all international standards for sFra, the FraX101 can be battery powered and has wireless communication with a computer.

the FraX150 offers all the benefits of sFra for diagnosis of damage to transformers, but it is built into a tough carry case and includes an on-board computer, making it a self contained unit. there is a large bright screen to make it comfortable to use even in direct sun light. Data can be stored on the hard-drive and can be downloaded using the galvanically isolated usB port. the FraX 150 utilizes PowerDB software.

the megger leakage reactance tester mlr10 is used to measure leakage reactance and other associated parameters in high voltage power transformers. leakage reactance, or more generally leakage impedance, is measured at the transformer primary winding while the secondary winding is shorted. Ideally, a transformer’s primary and secondary windings should be 100% coupled by magnetic flux, but in real transformers there is always a small amount of leakage flux. leakage inductance is a result of this leakage flux.

the Ba-185 Current transformer Burden ammeter is a rugged, portable instrument, designed to field-test current transformer installations

within the accuracy limits of the Ct, a good current transformer should not have a noticeable change in ratio when a secondary burden is added. this is because the primary effect of additional burden on a good Ct is a rise in the secondary voltage.

ttr25 ttr100

Transformer testing

Megger three-phase turns ratio and winding resistance testers share common test leads so all tests can be carried out without having to swap and re-connect leads. This speeds up testing substantially, especially on large power transformers with multiple taps. For transformer power factor testing, see DELTA4000 on page 36.

80 V transformer turns ratio testers

TTR300 series the ttr300 series of three-phase transformer turns ratio test sets are designed to measure the turns ratio of power, instrument and distribution transformers in a substation or manufacturing environment. the instruments are ideal for power transformer manufacturers. their unique testing procedures and storage capability allows an operator to set up and test difficult three-phase transformers in a fraction of the time compared to other ttrs.

the ttr300 series also measure the phase deviation of the transformer primary and secondary. this quickly indicates problems such as partial shorted turns and core faults. this is also useful in verifying phase errors in all types of potential transformers and current transformers.

each unit comes equipped with a remote-control switch for single person testing. this allows the operator to test transformers with ltCs very quickly.

the series consists of three instruments:

the ttr330 offers a new user interface which allows the operator to interact with the PowerDB oNBoarD software system via a full QwertY keyboard and navigation keypads on a bright 8.4” Vga full color screen. an advanced feature of the ttr330 allows the user to customize test forms via the full-version PowerDB software.

the ttr310 has the ability to store test results, upload results to a PC (via a rs232 serial port), and print them in the field via an optional thermal paper printer, without the use of an external computer.

the ttr300 is designed to be remotely controlled via a PC running PowerDB lIte (included) or PowerDB advanced or Pro. the ttr300 is field upgradeable to the ttr310 or ttr330.


the mto series delivers full eight-terminal/six-winding resistance measurement capability. It is designed to save time by testing all six windings without having to disconnect and reconnect leads. also, the simultaneous winding magnetization (swm) method gives fast and reliable measurements even on large transformers with delta configuration on the low voltage side. additionally, the mto series leads are interchangeable with the megger ttr300 series of three-phase turns ratio instruments which eliminates additional connecting time if performing the two tests together.

the mto series consists of two models:

the base model, the mto300, is designed to be remote controlled via PowerDB software on an external PC or a megger transformer test product with on-board computer.

the mto330 offers the same functionality as the mto300. However, it is equipped with an onboard computer featuring a full QwertY keyboard and navigational pushbuttons. It has an 8.4 inch full-color Vga transflective screen viewable in bright sunlight.

Single-phase transformer ohmmeter

MTO210

mto210 is a mains powered, field-portable instrument designed specifically to measure the DC resistance of all types of magnetic windings safely and accurately. Its main use is for all types of transformer windings but it can also test rotating machine windings and perform low-current resistance measurements on connections, contacts and control circuits.

three features combine to make this instrument unique:

n dual winding measurement

n load tap-changer testing

n auto safety discharge circuit

the dual set of potential inputs measure the resistance of the primary and secondary windings of a single- or three-phase transformer simultaneously speeding up the measurement.

to achieve a tenfold improvement in reading time, a balancing current is applied to the secondary to attenuate the circulating current induced when the test current is applied to the primary winding. when testing the windings and contact resistance on tap-changers with make-before-break contacts and voltage regulators, the internal shutdown circuit of mto210, which will be triggered by a voltage kickback of a few microseconds if the tap-changer contacts are opened, can be used to check for pitted or misaligned contacts as the instrument will shut down if either condition occurs. users are protected by the shutdown circuit safety feature: any inadvertent disconnection of a test lead or loss of power to the instrument will safely discharge the energy stored in the test sample.

PowerDB OnBoard – consistent and repeatable

PowerDB onBoard embeds the powerful PowerDB asset management software within instruments running the windowstm operating system, eliminating the need for an external computer. PowerDB onBoard brings field based users consistent, repeatable tests across instruments, unprecedented data analysis (including historical trend charting) and asset management tools, all from on-screen ‘forms based’ views.

also included are a number of new communication technologies, providing a near seamless interface between the instrument and optional peripheral equipment, such as an “in-lid” usB full-sheet thermal-paper printer, usB flash drive, and external PC (via ethernet port). For advanced users, a usB router can be connected to the instrument to provide simultaneous access to other equipment, such as a mouse or a keyboard. storage space is provided by either the internal flash memory or external usB flash drive – sufficient to save literally tens of thousands of test data sets.

Reduced training time

a common user interface reduces the training time needed to understand the different instruments that a busy test engineer has to use. New instruments with PowerDB onBoard such as ttr330 and mto330 are truly forms-based, have a large 8.4” full-Vga bright color display, and let you set up and control the instruments through on-screen test form views. on-screen test forms are exact replicas of the test forms which are printed as a permanent test form record once testing is complete. they are secure reports generated directly from instrument so no human interface is needed.

For more information about PowerDB software, see page 45.

Battery testing

Megger manufactures both impedance and capacity testing equipment used for verifying battery condition over time with trending software. These methods meet the battery testing requirements of NERC/FERC PRC005-2 standard. The impedance test measures the condition of the entire electrical path of the battery from one terminal plate to another. This reveals any weaknesses in cells and inter-cell connectors, and it is often used to establish a baseline value for the battery. The Battery capacity or discharge test is the only way to get an accurate value of the actual capacity of the battery. Regular testing will allow trending of the battery’s health and an estimation of the remaining life of the battery. Most battery systems are floating and have DC ground monitors that alarms when a ground fault is detected. Megger produces a line of ground tracers that can be used on energized systems.

50 V line ground fault tracer

BGFT

the BgFt is a manually balanced instrument that identifies, tracks and locates ground faults in unearthed DC battery systems on-line. It is effective in high electrical noise environments since the

strength of test current can be adjusted. this is useful

in industries where the power supply for operating measurement,

communication and control equipment is critical.

the Bgl battery ground fault locator tracks and locates ground faults on grounded DC battery systems. to save hours of unnecessary troubleshooting, the Bgl readily differentiates

between the resistive fault currents and capacitive

charging currents. this feature allows

the instrument to detect and track leakage paths, even

in the presence of surge-suppression

capacitors.


Load testers

TORKEL 800 series

torKel860 is built for testing battery systems ranging from 12 V to 480 V. It can handle a discharge rate of 110 a and offers the same benefits as the torKel840 including the ability to expand the system should a higher discharge rate be required.

Designed to be used for battery systems ranging from 12 to 250 V which are often encountered in switchgear and similar equipment, torKel840 can discharge a battery

at up to 110 a. If higher current is needed, two or more torKel840 units or extra load units (tXl) can be linked together. tests can be conducted at constant current, constant power, constant resistance or in accordance with a pre-selected load profile.

there is no need to disconnect the battery from its regular load to test it with torKel as the unit adjusts to include the load currents in the test parameters. there is a user adjustable alarm and shutdown to prevent deep discharge of the battery. torKel wIN software allows the progress of the test to be monitored in real time as well as recording the result, post-test analysis and report generation.

For use with the TORKEL, the TXL extra load unit allows the battery to be

discharged at a greater rate.

Data collection/management software

If It implementation is a problem, PowerDB can host your data on a dedicated server, to reduce reliance on company It systems.

this economic software package has been designed for utilities, oems, HV contractors, maintenance, service and commissioning companies. In fact, anyone involved in substation asset testing.

Easier management of test data

PowerDB offers a straightforward approach to data management. the basic step in creating this user-friendly package was to make test data entry screens and printed forms identical. users will appreciate that what they see on the screen is what they will get in the printed version. PowerDB simplifies testing and data management by allowing users to deliver reports electronically. the software will execute several tasks including equation calculations, temperature, correction factors and charting.

PowerDB helps predict possible equipment failure by trending results, which can be stored in PowerDB or imported from other software. this makes transitions to PowerDB easy.

Industry standard test forms are not always what a company needs. so PowerDB software allows the user to customize

forms. with a drag and drop feature anyone, even those without database experience, can create a form simply by dragging and dropping in tables, text boxes, images, charts and more, to create a customized form. and, with VBscript, calculations can be

Testing data management software

Do you have problems managing test data?

once tests have been done on site there is the issue of recording and managing the data. this may have been recorded by a number of field engineers or 3rd party contractors. How do you correlate all this data and store it so that it can be used efficiently for maintenance or referenced for auditing?

PowerDB software allows the user to manually enter test results into specifically designed forms for testing substation assets such as transformers, Cts, batteries and relays. It allows the user to quickly and easily enter the test results straight into a unique test data form on a laptop.

this form can then be sent over the internet to be synchronized with the PowerDB database, which stores and manages the data so that it can be easily referenced.

PowerDB is specifically designed for storing and managing data from commissioning and maintenance, including analysis and trending of test results.

PowerDB can then quickly create entire test documentation packages that include test reports, comment and deficiency summaries, table of contents and field service reports.

PowerDB’s test forms are designed to be used with each of the following product categories:

Batteries Insulation fluids Cables loadbreak switches Circuit breakers motor control Coordination data Power factor tests Disconnects relays generators switchboards ground fault tests transfer switches ground mat/grid tests watthour meters Instrument transformers transducers Power transformers

PowerDB


defined, tables looked up, and it can even interact with other applications. one time definition of common items can be used to put logos, headers and footers on every page or in

many multiple forms. one change will automatically update every form the common item is used in.

there are three ways to document testing using the PowerDB software. First and foremost,

data fields can be filled in using manual entry, standardizing the reporting of test results. second, forms can be filled in using other applications, including megger’s aVts, entering data into the fields using information stored in the other applications. Finally, the software can communicate directly with test and measurement equipment produced by megger.

Built-in report flexibilityPowerDB can create reports in one step, with customizable sorting of the order of test forms. Forms can be removed, and page numbering will be automatically adjusted. In a single print job, supplementary reports can also be printed at the same time as the primary report. the supplementary reports, including comment and deficiency summary reports, open up the data and information for all of the equipment tested on one job. Finally, all of the information can be generated for the on-demand world using the optional PowerDB web server. all of the user’s important information is published to the web and can be accessed from anywhere in the world.

Computerized maintenance management system supportmany electrical utilities and other company operations have invested in sophisticated Cmms systems, such as Digital Inspection’s Cascade and mro software’s maXImo. However, due to test instrument specific software packages and handwritten test results, these firms often struggle to get test data into their systems. one electric utility even referred to getting data into the Cmms as ‘feeding the monster’.

PowerDB’s speciality is ‘feeding the monster’! PowerDB allows you to link easily with the Cmms system so that the system can pre-populate the PowerDB equipment database, send PowerDB all work orders, add forms based on the job plans, and even return the measurement points, obtained from a multitude of test sets, back to the Cmms system.

Furthermore, megger will work directly with your Cmms personnel to integrate your data into your internal Cmms system.

the new PowerDB software package eliminates many common paperwork and recording problems. with the software, the number of man-hours devoted to preparing reports will be minimal. the user can customize the reports to be what a job requires but will not have to write the report, which is automatically generated by the software. Included in the reports are a table of contents, data sheets, as well as comment and deficiency summaries. PowerDB even comes with built-in spell check.

automatically generated professional reports means that a testing company, for instance, is able to complete jobs faster and in a more efficient manner. PowerDB is well-suited for technicians who prefer to spend a minimum

amount of time writing reports and want a more concise way to process data.

electronic records of test data can create a couple of different problems for companies and utilities. while many electronic records are hard to locate due to the vast amount of records kept on one system PowerDB makes it easier. By using its relational database it is much easier to find present and past records. and, because it has multiple safe guards, PowerDB prevents lost data. By saving documents that are in progress to multiple places, the problem of lost data is eliminated. PowerDB also synchronizes the date to several machines, meaning that a single crash does not create a costly loss of data.
