EDS30…
Portable Ground Fault Location System
for Ungrounded AC and DC Systems
Product description
The EDS30… is a portable ground fault location system for ungrounded AC and DC systems.
The system locates ground faults down to the load level in both energized and deenergized
circuits. The EDS... may also be used for branch ground fault current measurements
in grounded systems. All essential components are housed in a robust aluminum
casing.

Function
Ground fault signal generator PGH18…
For online systems: The PGH18… generates a defined test current signal. The test current
generated in this manner depends on the value of the present insulation fault and the system
voltage.
• Depending on the switch position of the PGH185 or PGH186, the test current is limited
to a maximum of 25 mA or 10 mA.
• The PGH183 limits the test current to a maximum of 2.5 mA or 1 mA depending on the
switch position.
For offline systems or systems < 50 V, the PGH186 drives a test current generated by an
integrated voltage source (DC 50 V). For systems > 50 V, the system voltage itself drives
the test current.
Ground fault evaluator EDS190P
The ground fault evaluator EDS190P provides the following measuring functions:
• Ground fault location. The EDS190P locates ground faults down to the load level by locating
the test current signal generated by the PGH18… device.
• Ground fault current measurements in grounded AC circuits.
The response range for ground fault current is 10 mA…10 A.
Displays
The full-featured LCD display includes many different indications, including the detection of
the ground fault test pulse (in ungrounded systems), the measured ground fault current (in
grounded systems), the accumulator capacity, alarm memory indication, and the set nominal
frequency. A buzzer also activates when the alarm occurs.
