1 General
What is EDS3065
Critical Use Before making use of the EDS3065 portable insulation fault location device, the user must have a
very accurate knowledge of its possibilities, the special circumstances relating to its systems, and of
certain hazards which are possible. Among the relevant points to be considered, particular attention
must be paid to the maximum test current. Depending on the switch position of the PGH185, this
is a maximum of 25 mA or 10 mA respectively.
The test current flows between the system and earth, not as a load current. Under unfavourable
combinations of circumstances (low impedance insulation fault in connection with the test cycle
of the test current), control errors cannot be ruled out in the case of sensitive system components
(SPC, relays). Account must be taken of this possibility prior to use. If appropriate, a lower test
current should be set, or the fault location device in this system should not be used.
Attention: the test current of the PGH185 may cause triggering of RCDs. Although the test
current is limited to a maximum of 25 mA (or 10 mA respectively), 30 mA RCD (for example) may
already respond between 15 and 30 mA.
The EDS3065 is a portable insulation fault location device for IT systems (unearthed systems). It
enables insulation faults to be located during operation and without system shutdowns.
The EDS3065 consists of:
• PGH185 Insulation Fault Test Device
• EDS165 Insulation Fault Evaluator
• PSA3020 and PSA3052 Clamp-on Probes
In the past, classical insulation fault location consisted of disconnecting system sections one after
another and then carrying out often laborious and protracted work to search for the faults. Modern
fault location devices such as the EDS3065, PKA3001 or EDS470 (installed as a fixed system) make
the fault location a good deal easier and shorter, and contribute in this way to a better power supply.
While insulation fault location is being undertaken with the EDS3065, any insulation monitoring
device which may be present must be disconnected from the system for the duration of the fault
location, if its internal resistance R is < 120 kΩ. This must be done by effecting an all-pole
interruption of the system coupling - it is not sufficient to switch off the supply voltage to the
insulation monitoring device.
Insulation monitoring devices with an Riof 28 kΩbring about a current conduction against earth
of approximately 14 mA. When a device is used with an Riof 120 kΩthe influence is negligible,
and in this case there is no need to disconnect.
The EDS3065 can be used to accomplish the following measurement tasks:
• insulation fault location in IT systems, AC 19.2 ... 575 V / DC 19.2 ... 504 V
• insulation fault location in IT systems, AC 19.2 ... 575 V / DC 19.2 ... 504 V in
combination with an EDS470 insulation fault location device as a fixed installation
• residual current measurement in TT and TN systems (earthed systems)

The Insulation
Resistance
General
One determining factor for the availability of an electrical system is the insulation resistance. It
appears at the head of the list of protection goals for electrical safety. This applies as a fundamental
principle, regardless of the form of the system.
A planning decision to construct a safe and reliable power supply with the goal of achieving
maximum availability means:
• constructing the power supply as an IT system. By doing so, greater operational safety
and reliability, greater fire safety, greater safety from accidents and a higher reliable
resistance to earth are achieved than in the case of a system form where the active
conductors are connected to earth.
• use of the correctly selected insulation monitoring device. The advantages cited in the
foregoing paragraph stand or fall with the selection of the A-ISOMETER which is
appropriate to the respective application. Unless there is functional monitoring, it is
impossible to utilise the advantages of the IT system. The desired high level of
insulation resistance cannot be maintained in the long term without continuous
monitoring.
• reduction of maintenance costs and outage times thanks to the use of an insulation fault
location device. Rapid location of an insulation fault immediately after it has occurred
is a long-cherished wish on the part of the maintenance staff. The fault is reported and
located without interruption of operations, and without the need for possible night and
weekend work. The actual repair can then be carried out at a suitable point in time.
The system operator makes the decision as to whether the insulation fault location
device to be used should be a fixed installation or a portable device.
• An alternative to power supply in the form of an IT system may be offered by a TT or
TN system which is equipped with residual current monitors and residual current
detection devices. While this does not make it possible to avoid switching off when a
first low-impedance fault occurs, it nevertheless guarantees a time advantage as far as
information is concerned. As a result, deteriorations in the insulation and creeping
insulation faults are detected at an early stage and a considerable number of shutdowns
are prevented in this way.
Ensuring that the insulation is well-maintained is a decisive factor as far as the reliability of the
power supply is concerned. This is only possible with the use of suitable monitoring devices. These
devices cannot prevent the insulation fault or the deterioration of the insulation. However, early
and rapid detection with information about the location of the fault will simplify maintenance to
an extraordinary degree.
Without suitable tools, fault location was (and continues to be) time-consuming and troublesome.
Week-end work was frequently necessary in order to locate the fault or faults while the system was
switched off.
Modern monitoring devices such as the EDS3065, EDS470 or RCMS470 solve these problems.
Thanks to the automatic location of the insulation fault, the necessary fault elimination is made
very simple and the required high level of insulation is maintained. Localising takes place during
continuous operation and it is not necessary to shut the system down.

TGH1266E - 05/04
General
Basic Standards
Terms and
Definitions
If a power supply is constructed as an IT system, the relevant standards require that the first
insulation fault to occur must be eliminated as quickly as possible.
IEC 364-4-41, Point 413.1.5.4 (Note)
It is recommended that the first fault should be eliminated with the shortest practical delay.
DIN VDE 0100 Part 410:1983-11, Point 6.1.5.7
It is recommended that the first insulation fault should be eliminated as quickly as possible.
Rapid insulation fault location is made possible thanks to insulation fault location devices such as
the EDS3065, EDS470 or RCMS470. In this way, the risk of the power supply being switched off
because of a possible second fault is considerably reduced.
At the present time, work is in progress on IEC1557-9. This document deals with devices for
insulation fault location in operational IT AC systems, IT AC systems with electrically connected
DC circuits and IT DC systems. This international draft standard lays down some special
requirements for insulation fault location devices in IT systems of up to AC 1000 V and DC 1500
V.
BENDER’s insulation fault location devices are based on this draft of IEC1557-9. As far as possible,
this operating manual attempts to use the terminology of the draft Standard, including the term
‘insulation fault location device’. This indicates not only that insulation faults with 0 Ω(faults to
earth) are found, but also insulation faults which involve resistance.
In addition, IEC 1010-1 is applicable. The title of this international Standard is ”Safety
requirements for electrical equipment for measurement, control, and laboratory use”.
I∆= fault current. The current which comes to flow through an insulation
fault.
I∆n= nominal fault current. The fault current at which the evaluator unit
responds under specified conditions.
I∆s= measured value of the discriminating fault current of the evaluator
unit.

Response Values
Caution
When a first insulation fault occurs in IT systems, a fault current flows which is essentially
determined by the leakage capacitances of the system. The basic concept in fault location is therefore
to close the fault current circuit for a short period over a defined resistance. As a result of this
principle, the system voltage itself drives a test current which receives a signal that can be evaluated.
The test current is generated periodically by the PGH185 test device (which is a component of the
EDS3065 system). The test current is limited in amplitude and time. As this happens, the system
conductors are connected alternately to earth over a defined resistance. The fault current which is
generated in this manner depends on the size of the insulation fault present, and on the system
voltage. It is limited to a maximum of 25 mA, and when I
max
= 10mA is set, it is limited to 10 mA.
For planning purposes, it should be noted that no system components are present in which this test
current can bring about a damaging reaction, even in unfavourable cases.
The test current pulse flows from the test device via the ‘live’ leads, taking the shortest path to the
location of the insulation fault. From there, it flows via the insulation fault and the earth lead (PE
conductor) back to the test device. This current pulse is then detected by the clamp-on probes or
measuring current transformers located in the insulation fault path, and is reported by the connected
EDS165 evaluator.
Theclamp-onprobes and/ormeasuringcurrent transformers areused as residualcurrenttransformers
- that is to say, the PE conductor is not passed through the transformer.
Important: normal commercial clamp-on probes or measuring current transformers must not be
used.
The response value is determined by the sensitivity of the EDS165 evaluator. In DC as well as AC
and 3 AC systems, this is 5 mA as an arithmetic average value.
The accuracy is +/- 2 mA of the displayed measurement value. System faults and excessively high
system leakage capacitances may have a negative influence on the accuracy.

Operation in the
RCM-Mode
In the RCM mode, the EDS3065 operates according to the principle of residual current
measurement. In this case, only the EDS165 evaluator unit with the clamp-on probe is used, and
the PGH185 test device is not required.
In accordance with Kirchhoff’s Law, the sum of the inflowing currents at every intersection in a
network is equal to the sum of the outflowing currents.
The two currents Ito and Ifrom are equal in
quantity but have different directions, so
that the resultant sum is zero. The EDS165
recognises this and no message is generated.
A portion of the current is flowing away
via an insulation fault RF. The sum of the
currents is no longer zero. If the residual
current is equal to or greater than the
response value, the EDS165 will generate
a message.
In the RCM mode, residual currents can be measured in one- and three-phrase TT or TN systems.
If the system leakage capacitance upstream of the clamp-on probe is sufficiently high, the EDS165
can also be used for measurements in one- and three-phase IT systems. Its suitability for this
purpose must be checked in each individual case.

Before commissioning, please check that all the components listed above are included. Do not
undertake any work with an incomplete system. If any components are missing, please contact a
Technical Adviser at BENDER.
Two different EDS3065 Insulation Fault Location Devices are available. The difference between
them is the supply voltage for the PGH185 Insulation Fault Test Device:
• PGH185 - supply voltage: AC 230 V
• PGH185-13 - supply voltage AC 90 ... 132 V
Prior to commissioning, it is absolutely essential to check whether the supply voltage of the
EDS3065 system matches the voltage of the mains supply. Operation of the EDS3065 with the
wrong supply voltage can result in the destruction of the PGH185 Test Device.
When working with the EDS3065, only use those components which are supplied with the system.
In particular, do not use any other clamp-on probes, measuring leads or measuring terminals.
The EDS3065 represents a complete system. In addition to the PSA3020 and PSA3052 clamp-
on probes which are supplied with the system, measuring current transformers can be connected
to the EDS165 insulation fault evaluator. These may be BENDER Measuring Current Trans-
formers which are already installed in the system.
The following types of transformers are suitable:
Measuring Current Transformers, Model Series W1-S35 ... W5-S210
Rectangular Measuring Current Transformers, Model Series WR ...
Split-Core Type Measuring Current Transformers, Model Series WS ...
Important: normal commercial measuring transformers must not be used!
This also applies to additional clamp-on probes or measuring current transformers from the
BENDER range.
Attention: if transformers are not being used, they must not be left open in the system. In this case,
the transformer terminals k u. l should be shorted.

The PG185 is activated by using its ON/OFF switch, and it generates a defined test current signal.
The voltage present in the system is used to drive the test current. The value of the test current which
is generated therefore depends on the value of the insulation fault that is present, and on the system
voltage. The test current is limited to a maximum of 25 mA, or to 10 mA when the switch is in
the 10 mA position. The test current flows from the system via the PGH185 and then through the
protective conductor (PE) and the insulation fault (or faults) back into the system. The test current
signal is registered by the clamp-on probes or measuring current transformers located in the fault
current circuit, and the sections affected by faults are displayed by the EDS165 insulation fault
evaluators whenever the operating threshold of 5 mA is exceeded.
If the PGH185 is active, the cycle LEDs light up alternately in time with the test cycle.
If the device is connected by terminals L1, L2, L3 (or L1, L2) to a system that is ‘live’ for operational
reasons the terminal must not be disconnected from the protective conductor (PE).
The test current flows between the system and earth. If unfavourable combinations of
circumstances arise (low-impedance insulation fault in combination with the test cycle),
control errors cannot be ruled out on very sensitive system components (SPC, miniature relays).
This possibility should be taken into account prior to use. If this possibility exists, then setting Imax
= 10 mA should be selected.
