A compact and light weight
High Voltage Testing Set The primary area of application is in-field testing of cables. High
voltage is generated by a high voltage transformer and a voltage
multiplier. Thanks to an operating frequency of 20kHz small
dimensions are possible. Packaged in a handy carrying case with
handles and carrying strap, the PGK units are portable and
therefore equipped for field applications.
Test voltages Type PGK50 PGK80
Max. test voltage 50 kV DC 80 kV DC
at an output current of: 2 mA 0.8 mA
Features - automatic, SF6insulated discharge unit
- timer (0-30 minutes)
- connection for an electric gate, emergency-stop switch and
external warning lamps
- connection for Y/t plotter for recording the current flow
- shielded high voltage cables with clamps for connecting the test
object
- integrated thermal switch
- carrying case with handles, foldable mounting legs and cable
compartment

1. Product Information
Discharge device
The discharge device of the PGK50/80 consists of a pressure tank
(overpressure = 3 bar) filled with insulatig gas (SF6sulphur
hexafluoride).A NC-contact and a discharge resistor are installed in
the pressure tank. The discharge resistance is 69kWincluding
transient protection and is configured for a maximum surge power
of 8.000Ws.
The discharge device works automatically and independent of
instrument position and remains activated even at power
failure.The response of the discharge device is a loud switching
noise.
Diagram 1 indicates the maximum permissable load capacitance
depending upon the selected test voltage.

Test voltage in kV
During two discharges: Observe 15 minute pause time!
With discharges < 8000 Ws: Reduce pause time accordingly!
After completion of a test wait at least 10 seconds after the
switching noise of the discharge device. Therafter handle the
test object as follows:
1. Discharge with discharge rod,
2. Ground,
3. Short out!
Do not open discharge device. Servicing the Testing Set may
only be performed by instructed service personnel.The local
rules and regulations regarding handling of SF6gas must be
observed.
