operation, no interruption to 

operation; 

• Reduction in costs because of 

reduced production stoppages 

• Reduced maintenance costs due 

to fast localization of insulation faults 

• Improved preventive and scheduled 

maintenance 

• Higher availability of power supply 

thanks to diminished interruption to 

operation.

adaptation to the electrical 

installation; 

• Measuring current transformers in 

various sizes and constructional 

designs; 

• Monitors and controls up to 360 CT 

circuits; 

• Information exchange between the 

individual devices via the RS485 

interface (two-wire); 

• Indication of the faulty circuit; 

• Indication of the test current flowing 

in each circuit. 


Function 

The EDS system works together with an insulation monitoring device that monitors the 

insulation resistance of the entire system. When an insulation fault is signalled by the 

insulation monitoring device, the EDS system starts fault location (automatically or 

manually) in order to determine the faulty circuit of the (IT) ungrounded system. 

When a first fault occurs in ungrounded systems, a fault current flows which is essentially 

determined by the system leakage capacitances and the insulation resistance. The basic 

concept in fault location is therefore to close the fault current circuit for a short period 

over a current-limiting resistance. As a result of this principle, the system voltage itself 

drives a test current which results in a signal that can be evaluated. 

The test current is generated periodically by the PGH471/473/474 test device. The test 

current is limited in amplitude and time. As this happens, the system conductors are 

connected alternately to ground (PE) via a current-limiting resistance. The test current pulse 

flows from the test device via the live conductors, taking the shortest path to the location 

of the insulation fault. From there it flows via the insulation fault and the ground conductor 

back to the test device. This current pulse is then detected by the measuring current 

transformers located in the insulation fault path, and is evaluated by the connected 

insulation fault evaluator. 

Sophisticated evaluation method and filtering prevent false alarms for ground fault currents 

up to 10 A/(1 A). The measuring current transformers are used as ground fault current 

transformers, i.e. the ground (PE) conductor is not led through the current transformer. 

The response value is determined by the sensitivity of the insulation fault evaluators 

EDS470-12/EDS473-12 or EDS165/165-3. The response value is 5 mA as arithmetic mean 

value in DC as well as in AC and 3 AC systems (EDS470) respectively 0.5 mA (EDS473).

Control and indicating device 

PRC470 

The control and indicating device PRC470 

performs the central control and 

monitoring function in EDS systems. The 

information exchange between the 

individual components of the EDS470 

system takes place via the RS485 interface. 

Apart from the control functions and the 

extended scanning possibilities, the 

PRC470 is used to setup the EDS470 

system to different system parameters. 

The PRC470 also may be set to operation 

with system interferences, e.g. caused by 

frequency converters with low-frequency 

leakage currents or switch gear and 

controls producing transient leakage 

currents. Additional problems may arise 

through EMC suppression capacitors 

which are more and more used to comply 

with the EMC requirements. 

Essential func tions ar e 

• Control and synchronization of the 

test cycle of the PGH47. test device ; 

• Indication via LC display; 

• Display of the respective test current 

in each CT circuit; 

• Display of the connections between 

current transformer and insulation 

fault evaluator EDS470-12/EDS473-12; 

• Test function for testing all devices 

connected; 

• Setting of the operating principle for 

each insulation fault evaluator; 

• Setting of the different measuring 

current transformer types used; 

• Setting via software menus; 

• Scanning of individual CT 

circuits. 

Insulation fault test device 

PGH471/473/474 

After detecting the insulation fault through 

the insulation monitoring device, insulation 

fault location is started via the 

control and indicating device PRC470. 

Once the insulation fault test device 

PGH471 is started, it produces a defined 

test current signal. The system voltage 

drives the test current. The value of the 

test current depends on insulation 

resistance, leakage capacitance and the 

system voltage. The test current is limited 

to max. 25 mA/(2.5 mA). The maximum 

test current can be limited to 10 mA/ 

(1 mA) via a DIP switch. This limitation is 

recommended when using the system in 

control systems with sensitive relays or 

SPS. 

If the PGH471/473/474 is active, both 

cycle LEDs light up alternately during the 

respective cycle. 

Insulation fault evaluator 

EDS470-12, EDS473-12 

The insulation fault evaluator EDS470-12/ 

EDS473-12 is controlled by means of a 

microcontroller. Together with the 

measuring current transformers it is used 

to evaluate test current signals generated 

by the insulation fault test device. 

The device subsequently evaluates the 

signals from all connected measuring 

current transformers. If the fault current 

detected by a measuring current 

transformer exceeds the response value, 

the respective alarm LED of the LED line 

and the alarm LED light up and the alarm 

relay switches. The alarm relay outputs a 

common alarm for all measuring 

channels. 

Up to 12 measuring current transformers 

can be connected to one insulation fault 

evaluator EDS470-12/EDS473-12. 

Connection l of the measuring current 

transformers must be wired in a star 

connection to terminal l of the evaluator 

EDS470-12/EDS473-12. 

All settings within an EDS system are 

carried out at the control and indicating 

device PRC470. 




Insulation fault location system for 

Ungrounded (IT) AC and DC systems 

Coupling device AGE470 

The EDS system is suitable for monitoring 

and scanning ungrounded (IT) systems of 

AC 45....65 Hz, 20...575 V and DC 20...500V. 

The voltage range of AC systems can be 

extended to AC 790 V, and that of DC 

systems to DC 960 V by means of the 

coupling device AGE470. 

Connection between the insulation fault 

test device PGH471 and coupling device 

AGE470. 

Measuring current transformers for EDS systems 

To meet the requirements of an electrical installation, different types of measuring 

current transformers are available for EDS insulation fault location systems. Measuring 

current transformers which are commercially available are not suitable for the EDS system 

and must not be used. 

Suitable measuring current transformers are listed in the table below. 

All measuring current transformers listed in the table are highly sensitive and convert 

even very small residual currents into evaluable signals. Connection to the insulation fault 

evaluator is carried out via two connecting leads. When installing please make sure that 

all current-carrying leads of the respective sub-circuit are passed through the current 

transformer. Te ground conductor must not be passed through the current transformer.

EDS470 / EDS473 

Construction of an EDS system 

The example of an interconnection 

diagram below shows a central insulation 

monitoring device IRDH265 monitoring, a 

three-phase system. If the insulation 

value falls below the preset response 

value, the PGH471 will be activated by the 

insulation monitoring device via the relay 

contacts 21/24. The insulation fault test 

device PGH471 is connected to the 

insulation fault evaluator EDS470-12 and 

the control and indicating device PRC470 

via the RS485 interface (terminals A and B). 

After the PGH471 is activated from the 

PRC470 via the interface, the EDS470-12 

starts scanning the connected measuring 

current transformers. The diagram 

opposite shows three connected 

measuring current transformers. The 

RS485 serial interface has to be 

terminated at both ends with a resistor of 

120 Ω. 

The common connection I to the measuring 

current transformers must be


Example of an interconnection diagram of an EDS system with SMO480-12, DI-1 and FTC1500 

Construction of an EDS system in combination with SMO480-12, DI-1 and FTC1500 

The interconnection diagram above 

illustrates an extended EDS system. The 

following components have been 

integrated into the classical EDS circuit: 

- SMO480-12 

(signal converter) 

- DI-1 

(RS485 repeater) 

- FTC1500 

(protocol converter) 

The SMO480-12 signal converter 

converts serial information from Bender 

evaluators into relay signals. There is one 

relay available for each of the measuring 

channels of the evaluators. The SMO480- 

12 signal converter allows faulty circuits of 

the system to be switched off in an 

insulation fault location system. In this 

way, a failure of the entire electrical 

system can be prevented. The RS485 

repeater DI-1 amplifies the signals of the 

RS485 interfaces. In EDS systems with a lot 

of circuits to be monitored, the maximum 

bus length of 1200 m often is not 

sufficient. Here the use of a DI-1 can 

extend the RS485 bus length to additional 

1200 m (4000 ft). As a side effect the 

number of the maximum possible bus 

nodes can be increased by 32. 

The EDS system (insulation fault location 

system) communicates via the RS485 

interface using the BENDER BMS protocol. 

The protocol converter FTC1500 is a 

communication bridge between a RS485 

interface using the BENDER BMS protocol 

and an interface using the JBUS/MODBUS 

protocol, that allows the EDS system to be 

integrated into the JBUS/MODBUS 

environment.

System extensions, accessories 

The portable insulation fault evaluator 

EDS165-3 represents an ideal 

complement to the EDS system where 

EDS165 is suitable for EDS470 systems 

and EDS165-3 for EDS473 systems. 

The respective device can be used to track 

the fault location or to check additional 

subcircuits manually. 

The EDS165-3 is used in combination with 

current clamps.It detects the test current 

signal of the insulation fault test device 

PGH47. and works well with an existing 

EDS 47. system. 

The EDS165-3 is supplied via batteries. The 

operation and settings are carried out by 

means of the function keys and the LC 

display. 

Three current clamps are suitable for the 

EDS470 system. These are PSA3020 (with 

an internal diameter of 20 mm), PSA3052 

with an internal diameter of 52 mm and 

PSA3165 (with an internal diameter of 

100 mm). 

The current clamps PSA3320 with an 

internal diameter of 20 mm and PSA 

3352 with an internal diameter of 52 

mm are suitable for the EDS473 system. 

The clearly legible LC display indicates the 

actual test current flowing in the 

respective circuit and indicates if the 

alarm value has been exceeded. 

Furthermore it indicates which current 

clamp has been selected, the battery 

charge, the selected system frequency, and 

the mode of the buzzer.

The EDS165(-3) in combination with any 

current clamp can be used as a portable 

residual current monitor in grounded and 

high-resistance grounded. The operating 

mode can be changed by means of a 

selector. 

For detailed information about portable 

insulation fault location refer to the 

technical manuals EDS3060 and EDS3065 

respectively EDS3360 and EDS3365. 

Insulation fault test device PGH185/PGH183 

The insulation fault test device PGH185/ 

PGH183 is used to generate a defined test 

current 

which is generated therefore depends on 

the value of the insulation fault that is 

present, the leakage capacitance and on 

the system voltage. The test current is 

limited to a maximum of 25 mA/2.5 mA 

respectively max. 10 mA/ 1 mA depending 

on the switch position of the Imax switch. 

The test current flows from the system via 

the PGH185/PGH183 and then through 

the ground conductor (PE) and the 

insulation fault(s) back to the system. The 

test current signal is sensed by the current 

clamps or measuring current transformers 

located in the fault current circuit , and the 

faulty circuits are indicated by the

signal. It is applied in systems which do 

not include a permanently installed EDS 

system. Insulation fault location is carried 

out by means of the insulation fault 

evaluators EDS165(-3) and the respective 

current clamps. The PGH185/PGH183 is a 

component of the EDS3065 respectively 

EDS3365. 

After switching on the PGH18. 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
