The discharge device of the PGK50/80 consists of a pressure tank
(overpressure = 3 bar) filled with insulatig gas (SF
hexafluoride). A NC-contact and a discharge resistor are installed in
the pressure tank. The discharge resistance is 69k including
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.

During two discharges:
With discharges < 8000 Ws:
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
