General charateristics
Back-up fuse-linksBack-up fuse-links have a “rated minimum breaking current”from which the fuse-links are able to interrupt current.Backup fuse-links are not supposed to operate below their“minimum breaking current” (below l3). Their operating range is from l3 to the maximum rated breaking current (l1).For the assignment of back-up fuse-links, it is important to note that the lowest short circuit current is higher at the site of theHV back-up fuse-link than l3 (IKmin > I3).If the short circuit current is lower than the minimum breaking current, additional protection must be provided.
StrikerThe striker of HV fuse-links in this product list has an effective length of 30 mm and is a «medium» type. This classification results from the energy released by the striker between the points A and B (within the first 20 mm of the operatingdistance. The initial force is about 80N, the force at the end of free movement is about 15N.The striker serves for actuation of the trip-free mechanism of the switch
Rated voltage rangeIt is important for HV fuse-links that they must be operated at the voltage for which they have been rated. Accordingly, the operating voltage corresponds to the maximum rated voltage of the fuse-link. Owing to the switching voltage occurring during arcing, the fuse-link cannot be used at lower voltages without limitation. A lower operating voltage at which the fuselink can still be used without exceeding the system insulation level during extinction must therefore be taken into account. From these two values results the permissible voltage range of the fuse-link, which is shown on the fuse-links or in the technical data, e.g. 10/24kV.

Dimension
Breaking capacity I1The breaking capacity is also referred to as the “rated maximum breaking current”. This clearly indicates that this is the maximum current which can be interrupted by the fuselink. I1 of the fuse-link must be greater than the maxi-mum short circuit current at the site of the fuse-link (I1 > IKmax).
Minimum breaking current I3The minimum breaking current is referred to as the “rated minimum breaking current”. This value must be specified for back-up fuse-links. From this current, back-up fuse-links are capable to breaking fault currents. The fuse-links must be assigned to the system so that no fault current below I3 can occur at the site of the fuse-link (due to the system parameters or other protective devices).
Power dissipation of a fuse-link PwarmThe power dissipation of a HV fuse-link is specified at the rated current of the fuse-link. For protection with HV fuse-links, it should be noted that the operating current is normally half the rated current. Because of the physical relationships, the actual power dissipation is less than a quarter of the value Pwarm for HV fuse-links shown in the technical data table.
Time-current characteristic (I/t characteristic)The time-current characteristic shows the correlation between current and time up to the melting of a fuse-element. The virtual time (tvs) is specified to enable a comparison of the l/t characteristics of fuse-links below 100ms. For co-or-dination with other protective devices, e.g. load interrupter switches or circuit breakers, the melting integral I2t must be referred to for melting times below 100ms.
Current limitationAt high short circuit currents, HV fuse-links interrupt current within several milliseconds that means, the sinusoidal current does not reach its peak value and that HV fuse-links are current limiting devices. This is a significant advan-tage compared to mechanical switches whose contacts take longer to open and interrupt currents at natural zero. During this time, the peak short-circuit current is able to freely develop its dynamic force. By using HV fuse-links, this surge current is limited within several ms to a fraction of its peak value and the design of the subsequent system can be reduced in terms of dynamic forces.
Switching voltageSo that HV fuse-links perform a current-limiting action, the short circuit current must be limited and reduced as it increases.This requires a switching voltage that exceeds the driving system voltage and forces the current to zero. This swit-ching voltage must not exceed the specified permissible value of 2.2 times the peak value of the maximum rated voltage. Limitor HV fuse-links are within this limit.
ApplicationLimitor HV fuse-links type CPD meet the requirementsof IEC 60282-1 and were specifically developed to beinstalled in compact sized enclosed SF6 insulated substations.In these substations HV fuse-links are enclosedin narrow fuse compartments which on the one handprevent efficient cooling of the fuse-links and on theother hand have a limited thermal power acceptancethemselves. Overheating of fuse compartments insuch enclosures is, however, not to be expected, if thefuse-links have been properly selected by their ratedcurrent according to the transformer to be protected(see table 3) and if the melting elements of the fuselinsare in faultless condition (Fig. 8).One or more of the melting elements connected inparallel may, however, be interrupted by transient currents caused by transformer inrush or lightning strikes.Fuse-links having one or more of the paralleled meltingelements interrupted, dissipate significantly more heat than faultless fuse-links. There is a certain risk that the limited power acceptance of fuse compartments may be exceeded at or even below rated transformer current. HV back-up fuse-links type CPD prevent such potential overheating when installed in conjunction with a transformer switch having trip-free mechanism.
Function modeThe CPD striker system controls the power dissipationof the fuse according to Ohm’s law (CPD means controlled power dissipation). The striker pin is released depending on the voltage drop across the fuse and,therefore depending on the power dissipation. Therelease voltage of the CPD striker system has been selected so that the fuse carrying the operating current IB does not exceed the limiting value. The CPD striker system controls the power dissipation of the fuse and releases the transformer switch before the permissible power acceptance of the fuse compartment will be exceeded (Fig. 8).

High-voltage alternating current switch-fusecombinations acc. to IEC 62 271-105In order to increase the utilization range of a switch, it is combined with current limiting HV fuse-links. This combination unit offers short-circuit protection in addition to load switching capacity. HV fuse-links provide short-circuit protection, while the switch interrupts the currents below the take-over current of the combination unit.In addition to the inrush current, short-circuit current onsecondary terminal short-circuits and low voltage selectivity,the following switch characteristics should be taken intoaccount:– Rated transfer current (ltransfer)– Fuse-initiated opening time of the switch (t0)Fig. 9 shows the rated transfer current (ltransfer) as a vertical line.The fuse-initiated opening time (t0) must be multiplied by 0,9 (procedure according to IEC 62 271-105) and a horizontal line be drawn. This results in an intersection that is characteristic to the switch and must be established for each switch individually.
This switch intersection divides the sheet into four quadrants (see Fig. 9).Suitable for the switch-fuse combination are HV fuse-links only with a time-current characteristic that does not pass through quadrant IV (“forbidden area”).Generally suitable for use in switch-fuse combinationsaccording to IEC 62 271-105 are all HV fuse-links with striker which meet this criterion.Ferraz Shawmut has assigned HV fuse-links to the switch-fuse combination and the transformers of all major manufactures. These documents are available on request.

PresentationFR-type fuses are designed to protect HV/LV power distribution transformers. Designed to be coordinatedwith other equipment, these current-limiting fuses interrupt fault currents before they reach their peak. Thefault current is interrupted inside the fuse body and although this is very fast there is no sign of it outside.The main elements in these fuses are:• a barrel of class F insulating synthetic material• nickel plated aluminum end contacts• very pure silver fuse elements• composite material fuse element holder to withstand high temperaturesThanks to their structure, based on a synthetic material, FR fuses are the perfect answer to the stresses involved in use inside HV bays and fuse chambers.

ApplicationMedium-voltage distribution systems that supply industrial plants, shopping centers, hospitals, schools, office buildings and underground residential service often require special types of overcurrent protection. This is of par-ticular importance because, in the event of a fault, these types of systems frequently produce high short-circuit currents that may result in damage to busway, motors, switches and other equipment. Current-limiting power fuses are widely used in these applications because they afford excellent over-current protection and noiseless operation, and because they can be used in confined spaces. The amount of damage in the faulted area and the mechanical stress and strain on busway, switches and other apparatus carrying the fault current is proportional to the square of the current and to the length of time the fault persists. By limiting the let through energy at the fault, properly applied current-limiting fuses assist in limiting or preventing short-circuit damage to busway, circuit breakers, switches, and other electrical components. Current-limiting power fuses are manufactured in ratings ranging from 0.6 kV through 38 kV and in continuous current ratings from 0.5 amperes through 900 amperes. Various designs are available for use with motors, transformers, capacitors, and circuit-protection equipment.
Product FeaturesCurrent-limiting power fuses offer significant advantages for protecting electrical power systems and equipment.Advantages include:—High interrupting capacity—Noiseless operation, since the interruption is totally contained—Fast current-limiting operation when troublesome high available fault currents are encountered—No pressure build-up, therefore, no vents or special reinforced compartments are required

PresentationThe insulation fault indicator is presented in the form of a compact case made of a highly sturdy syntheticmaterial. A window on the front enables the viewing of a red warning light in case of operation. Thissignal may be seen from 10 meters away, across a 120 ° sector.The IDT20 Comp counts current pulses due to lightning - A6- digits electromechanical meter indicate thenumber of lightning strikes.
Two conductive contacts on the front allow the indicator to be reset.
The case contains a 16 mm diameter hole for the passage of a ground cable. The indicator is deliveredwith an 80 cm cable section and two crimping sleeves to prevent the ground circuit from being cut duringinstallation. Two openings on the back enable the device to be attached to the pole by metal strip.
OperationGround currents caused by insulation faults are measured by an integrated current transformer. An electro-nic panel processes the transformer output signal and controls the operation of the warning light in theevent it exceeds a preset threshold. The signal is maintained even after power on the line has been dis-connected, enabling the operator to quickly detect the fault location.
Resetting and testing of the indicator are ensured by an IDT 101 type reset device.

Functional descriptionGround faults in generalIn networks with directly earthed zero-point, aground fault is equivalent to a phase-to-groundshort circuit. In that case the current magnitude willbe somewhat less than in the case of a phase-to-phase short circuit. For networks that do not havedirectly earthed zero-point, the magnitude of thesingular ground fault current is ruled by the size ofthe galvanically interconnected network, voltagelevel, type of cable and the zero-point equipment.Ground Fault ElementThe Ground Fault Element is a summing currenttransformer (CT) which generates a current whenthe vectorial sum of the 3 phase currents becomesdifferent from zero, i.e. during ground fault. Withno ground fault, the vectorial sum is approximately zero.
MountingGround faults in ElementThe element connects to the indicatorvia its ready-mounted cable (2.0 m).Multi-core cable: The element is mounted on the screened part of thecable, below the stripback point,according to the mounting instruc-tions. The screen is turned back under-neath the flexible CT-core and termina-ted at the ground point. The principleis shown in figure opposite.
Ground faults IndicatorThe Indicator should be mounted in a readily visiblelocation. It can be mounted on a pole or a wall withthe two enclosed self-threading screws. The Indicatoris also suited for mounting with stainless steel or PVCcable ties. Both options are illustrated in figure above.Remove the front cover of the indicator to accessholes for screws/ties. See figure for further details.
Mounting of Ground Fault Indicator
OverviewCabletroll 2500 is a ground fault sensing system. Itconsists of a Ground Fault Element and GroundFault Indicator. It can be mounted in high voltageunderground cable distribution networks with sys-tem voltage from 6 to 36 kV.
The sealed Ground Fault Element mounts on mostwidely used cable types, while the weatherproofindicator is well suited for outdoor mounting (Seefig. 1).
The indicator is fitted with a high intensity LED forlocal indication and an optional Xenon flash unit. Itis also equipped with a pair of relay contacts forconnection to remote indicators, which communi-cate via cable and/or radio.
The trip level for ground fault can be set on-site tofixed values of 40A, 80A or 120A. It is factory set to40A. In addition, the trip level can be continuouslyadjusted in the ranges 5-40A, 8-80A or 12-120A.

Directional fault current indicatorfor underground systems
Presentation
CABLETROLL 3600 directional Fault Current Indicators (FCI) are designed to help the operator locate faultson underground lines. They detect both single phase-to-ground (PTG) and phase-to-phase (PTP) faults insystems with 300A impedance or compensated neutral grounding. And they use a brand-new detectiontechnique that offers significant advantages over the conventional technique of existing detectors workingon current thresholds. That new technology means that unlike conventional detectors, they can operateon systems with high capacitive current (combined overhead/underground networks with a high propor-tion of cable, very long underground networks).
The CABLETROLL 3600 FCI is capable of discriminating between PTP and PTG faults, and indicating thedirection of the latter type.
It can be used on networks from 6 to 36 kV for the following applications:
CABLETROLL 3600 LDAC: installed on strategic points in the network (switching points, branching points), it assists theoperator by visually signaling the passage of a PTG or PTP fault current.
CABLETROLL 3600 LDAC LV: when used in combination with remote-controlled switchgear, it assists the operator in remote control by providing contacts that alert the remote control system to the passage of a PTG or PTPfault current.
CABLETROLL 3600 LDAU:installed temporarily on a disturbed network, it identifies what sections are responsible for faultsand gives a time and date system the data required to analyze faults, whether persistent or transient.

The CABLETROLL 3600 works on the principle of directional fault indication described in EDF patent 9209549.The following block diagram shows the CABLETROLL 3600 indicator's main circuits.
In the initial milliseconds after a PTG fault, voltage and current transients are generated on the system.Using a microprocessor to interpret the phase displacement between residual voltage and residual current,the circuit can indicate in which direction the PTG fault is located (up-line or down-line of the indicator'spick-up coils).For PTP faults the working principle is that of an ammeter (current threshold).

MV Fault IndicatorCabletroll 3600
General
When a CABLETROLL 3600 detects a fault current, it alerts the operator either visually with a signal lightor through contacts (CABLETROLL 3600 AC LV or AU).As soon as the existence of a fault is confirmed, the signal light on the CABLETROLL 3600 lights up andstays lit until one of the following events occurs:
• Forward voltage returns to the HV line (voltage reset).• The internal 2 hour time delay ends (timer reset).• The indicator is reset by the operator using either the reset button on the front of the main box or the
COMTROLL infrared remote control unit (manual reset).
PTG fault indication
The principle of directional PTG fault indication is tolocate what part of the line is the origin of a PTGfault. To do this each pick-up coil has a GREEN sig-nal and a RED signal. The coils must be mountedin such a way that the GREEN signal is on the BUS-BAR side and the RED signal is on the NETWORKside.
If the GREEN signal light is lit up, the fault is on theGREEN side, i.e. the BUSBAR side.
If the RED signal light is lit up, the fault is on the REDside, i.e. the NETWORK side.
PTP fault indication
In this case the CABLETROLL 3600 FCI works like a conven-tional fault indicator and no direction is indicated. All the faultindicators between the feeding substation and the fault flashthe green signal light and the red signal light alternately(once every second).

PTG faultsAny PTG fault characterized by a residual currentover 60A peak + 10A and a residual voltage of 9kV+ 2kV is detected.
Once those thresholds are exceeded, the fault indi-cator waits 40 ms to detect a residual voltage Vrgreater than 3.5kV ± 0.5kV before indicating thatthere is indeed a fault.
Double PTG faultsA fault considered as a "double PTG fault" consistsof a simultaneous PTG fault on two different phasesin a system powered by the same HV transformerbut grounded at two geographically distant points.
The two faults may be located on the same feederor on two different feeders. In this case any faultcharacterized by a residual current over 250Arms ±50A is detected.
PTP faultsAny PTP fault characterized by a current over450Arms + 80A is detected.
Return of forward voltageThe return of forward HV voltage (resetting the FCI)is accepted when voltage on the system is at least10kVrms + 2kV.
The CABLETROLL 3600 FCI consists of six parts:
• Voltage measurement:subassembly consisting of a male WAGO-type ter-mination ref. 723-604/000-042 (see connectiondiagram) connected to a 7 m (or optional 12 m)cable. This cable is then connected to the termi-nal block on the main unit of the FCI. The maleconnector is connected to a female part (not sup-plied with the FCI) that leads to the portable ter-minations for disconnectable connectors (not sup-plied with the indicator).
• Current measurement: subassembly consisting of three current sensors,each with a detection element with its own cableand a collar to fasten the sensor on the HVcables. The three cables running out from thesensors are fitted with a current transformer (CT)connector (see connection diagram) that must beconnected to the current sensor cable (see hereafter).
• Current sensor cable:7 m (or optional 12 m) cable connected to a con-nector. One end of this cable must be connectedvia CT connectors to the current sensors and theother to the terminal block of the main FCI unit.
• Multi-core cable: 7 m (or optional 12 m) cable to connect the dis-play unit to the main FCI unit.
• Main unit containing:the electronic board, the power supply, the TESTand RESET buttons and the terminal blocks forconnection to outside elements.
• Display unit consisting of a weatherproof and impact resistant casing containing the green and red signallights. This unit must be installed outside the substation or the cubicle.

MountingLinetroll 111K mounts with screws (included) or wrapping bands. This enables installation on either woodor concrete poles.
Functional descriptionLinetroll® 111Ks fault sensing is based on detectionof the electromagnetic field below the conductors.The unit is fully self-contained; no external transfor-mers or connections of any kind is required.To determine whether or not the line is faulted, theindicator looks for a specific sequence in the lineconditions before it starts flashing. The generalsequence is as follows.
1. The line should be energized for at least3 seconds.
2. The line current should increase rapidly above thevalue set by the user (the nominal trip level).
3. The line should be de-energized.However, theuser may program the operating criteria to suitlocal requirements by manipulating a bank ofmicroswitches inside the indicator.
OverviewLinetroll® 111K indicators are used to locate short-circuit and earth faults in overhead power distribution networks. Linetroll 111K is a 3-phase unit fully covering the different types of potential fault configurations.
Indicators are placed at strategic locations along the line, such as after branching points and sectionalisers.The indicator may be pole-mounted, 3-5 meters below the conductors, by means of screws or wrapping-bands. Live line mounting is done safely, easily and rapidly.
Upon detection of a line fault, the indicator gives off an intermittant Xenon gas flash. This flash can be seenat up to 200 - 300 metres distance in full daylight and 2 - 3 km at night. The indicator lens allows for uni-form 360 degree monitoring. Upon fault sensing, all indicators installed between the feeding substation andthe fault will operate. Indicators place behind the fault remain idle.

DIRECTIONAL FAULT CURRENTINDICATOR FOR OVERHEAD LINES
Presentation
LINETROLL® 3500 is a pole-mounted intelligent Fault Current Indicator (FCI) for use in electrical power net-works. It uses brand-new detection technology that provides major benefits over previous FCI technology.LT3500 aims at tracking down the fault site rather than monitoring the exact fault current level.
FCIs contribute to improving the quality of supply in electrical distribution networks by providing instantinformation about fault sites. Based on this information, power rerouting and repair work can commencequickly. Outage duration and the use of manpower for fault-searching can be reduced by as much as 75%,a substantial saving potential for any utility.
For Distribution Automation (DA) purposes, or in combination with remote-controlled switchgear, FCIsused as in-formation sources represent a good alternative to automatic reclosers and sectionalisers.Reconnection of faulted lines as well as disconnection of healthy lines is avoided. Wear and tear of person-nel and equipment is reduced.
Strategic application (large numbers) of FCIs represents an important tool in the search for optimum elec-trical energy supply quality and price. For any utility, the use of FCIs translates to increased earnings andimproved goodwill and credibility among customers.
LINETROLL® 3500 is designed for application on 1- or 3-phase overhead distribution lines at voltages from6-132 kV. It is able to discriminate between phase-to-phase (PTP) faults and phase-to-ground (PTG) faultsand offers direc-tional capabilities on PTG faults, pointing towards the fault site.
LT 3500 represents a breakthrough in FCI performance and is applicable in networks of any neutral earth-ing method. The basic version of the unit exhibits 1 out of 2 available factory default characteristics, exclu-sively tailored for service in the following types of network: solid earthing versus impedance earthing orisolated networks.
It is designed to flawlessly meet the challenges of networks that undergo extensions and/or modifications,power re-routing and heavy load variations. All of this without the need for time-consuming networkcapacitance and fault current magnitude calculations, saving a lot of expensive time. The trick is that, con-trary to earlier fault indicator generations, LT3500's performance remains uninfluenced by capacitive dis-charge currents when applied in isolated or impedance earthed networks.
Unmatched application flexibility and product lifetime is achieved through modular hardware design andsoftware upgradeability.
Several methods of fault detection can be utilised simultaneously, offering many possibilities for adaptingthe function of the unit to some of the protection relay characteristics.
Maintenance requirements are very low thanks to sophisticated power management and a selection ofpower supply packs of adequate capacity.

APPLICATION OF LINETROLL® 3500
When LT3500 detects a fault current, it will indicatethis by flashing lights or by other means (optional).The unit is able to discriminate between PTG andPTP faults on any kind of network with regard to theearthing method in use.
The fault indicator light will keep flashing until a pre-determined automatic reset condition is fulfilled.Such an automatic reset condition can be the returnof voltage to the line (voltage reset), time lapsedsince fault occurred (timer reset) or other.
Manual reset can be carried out on-site by rotatingthe display unit to the RESET position, either byhand or by use of a special TEST/RESET TOOL. Thetest/reset tool must be used when the indicator can-not be reached from the ground.
Performance in coil- (Petersen), coil+ resistor-, resistor earthed networks and isolated networks.
PTG faults
All LT3500s mounted in the network supplied fromthe same feeder will indicate, flashing a single-colorlight, red or green. The color determines the relativedirection to the fault site.
When approaching the front of the indicator, i.e.when you see the indicator in front of the pole:
a) if the indication color is red; turn back alongthe line, the fault site is in the opposite direction
b) if the indication color is green; continue for-ward along the line, the fault site lies ahead
PTP faults
LT3500s mounted along the fault current path be-tween the feeder and the fault site will indicate,flashing alternating red and green lights.
Bi-colored alternating indication means that a PTPfault has occurred downstream from the indicator.

The criteria for detection and indication of PTG and PTP faults can be programmed individually, compris-ing a combination of di/dt and overcurrent techniques.
Only LT3500s mounted along a fault current path between a feeder and the fault site will indicate by flash-ing lights.
Inversely, a fault site should be located downstream from a flashing FCI. More precisely, the fault site shouldbe located between the last flashing FCI and the first idle FCI.

MV Fault IndicatorLinetroll 3500
LT3500 is the result of several years of research, development and testing aimed at setting new standardsfor re-liability and functionality of FCIs.
A few hintsThe unit continuously monitors the electromagnetic field on site. It looks for particular sequences of fieldchanges to take place. Upon recognition of such a sequence, the unit samples and stores information inmemory for immediate analysis. Based on analysis, the unit either indicates a faulted line or resumes triv-ial surveillance. The exact sensitivity to fault current magnitude is not critical for correct operation.
Fault category displayPhase-to-Ground and Phase-to-Phase faults can be indicated individually, as can transient faults versus per-manent faults. For on-site monitoring, faults are indicated by flashing lamps in the display unit. The flash-ing pattern defines what kind of fault the unit has detected. The display unit can be rotated horizontallyto allow easy monitoring from any position.
DirectionalityA great advantage to LT3500 is its directional capability. In impedance earthed or isolated networks theunit is able to tell its relative position to a phase-to-ground fault site.
MaintenanceMaintenance of FCIs normally involves replacing the batteries. A range of battery packs is available forLT3500, allowing some flexibility with respect to service intervals.

The LINETROLL 3600 FCI is capable of discriminating between PTP and PTG faults, and indicating the direction of the latter type.
It can be used on networks from 6 to 132 kV for the following applications:
LINETROLL 3600 PDAC: installed on strategic points in the network (switching points, branching points),it assists the operator by visually signaling the passage of a single- or multi-phase fault current.
LINETROLL 3600 PDAT: when used in combination with remote-controlled switchgear, it assists the oper-ator in remote control by providing contacts that alert the remote control system to the passage of a PTG orPTP fault current.
LINETROLL 3600 PDAU: installed temporarily on a disturbed network, it identifies what sections areresponsible for faults and gives a time and date system the data required to analyze faults, whether persist-ent or transient.

Description and working principle
The LINETROLL 3600 works on the principle of directional fault indication described in EDF patent 9209549.The following block diagram shows the LINETROLL 3600 indicator's main circuits.
In the initial milliseconds after a PTG fault, voltage and current transients are generated on the system. Usinga microprocessor to interpret the phase displacement between residual voltage and residual current, the cir-cuit can indicate in which direction the PTG fault is located (up-line or down-line of the support the pole isstrapped to).For PTP faults the working principle is that of an ammeter (current threshold).

Application of a LINETROLL 3600 FCI
General
When a LINETROLL 3600 detects a fault current, it alerts the operator either visually with a signal light orthrough contacts (LINETROLL 3600 AT or AU).As soon as the existence of a fault is confirmed, the signal light on the LINETROLL 3600 lights up and stayslit until one of the following events occurs:
- Forward voltage returns to the HV line (voltage reset).- The internal 2 hour time delay ends (timer reset).- The operator resets the fault indicator using either the "manual" system on the box or the COMTROLLinfrared remote control unit (manual reset). The device can be reset manually by turning the display unitto the signal light reset position and then turning it back to its original position.
PTG fault indication
The principle of directional PTG fault indication is to locate what part of the line is the origin of a PTG fault.To do this, the LINETROLL 3600 PTG fault indicator has two signal lights:- A Red light on the front of the box- A Green light on the back, on the side where the device is supported.
If the GREEN signal light is lit up, the fault is onthe GREEN side, i.e. the side of the support.
If the RED signal light is lit up, the fault is on the REDside, i.e. the side opposite the support.
PTP fault indication
In this case the LINETROLL 3600 FCI works like a convention-al fault indicator and no direction is indicated. All the fault indi-cators between the feeding substation and the fault flash thegreen signal light and the red signal light alternately (once every second).

Sensitivities are defined in the reference set-up shown below. Please inquire for any other set-up desired.
PTG faults
Any PTG fault characterized by a residual current over60A peak + 10A and a residual voltage of 9kV + 2kVis detected.Once those thresholds are exceeded, thefault indicator waits 40 ms to detect a residual voltageVr greater than 3.5kV + 0.5kV before indicating thatthere is indeed a fault.
PTP faults
Any PTP fault characterized by a current over 450Arms+ 80A is detected.
Double PTG faults
A fault considered as a "double PTG fault" consists ofa simultaneous PTG fault on two different phases in asystem powered by the same HV transformer butgrounded at two geographically distant points. Thetwo faults may be located on the same feeder or ontwo different feeders. In this case any fault character-ized by a residual current over 250Arms + 50A isdetected.
Return of forward voltage
The return of forward HV voltage (resetting the FCI) isaccepted when voltage on the system is at least10kVrms + 2kV.
The LINETROLL 3600 FCI consists of four parts:
• A support to be strapped on the pole with a metal strip. Thatsupport may have openings for wiring to connect the deviceto other equipment and a connection to a time and date system.
• A main box containing the sensors, the electronic boards andthe batteries.
• A display unit on the bottom of the box. That display unit maybe rotated 90° to improve visibility if required. It is also usedto reset and test the fault indicator.
• A top cap screwed onto the main box. That cap may beequipped with an optional solar panel to power the FCI.
