1. Product Information
Discharge device
The discharge device of the PGK50/80 consists of a pressure tank
(overpressure = 3 bar) filled with insulatig gas (SF
6
sulphur
hexafluoride). A NC-contact and a discharge resistor are installed in
the pressure tank. The discharge resistance is 69kW 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.
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 SF
6
gas must be
observed.
