Safety Precautions, Warranty
Safety Precautions, Continued
- It is imperative to every person who is involved with the
installation, start-up, operation and maintenance to have read
and understood the complete Operating Instruction.
- It is the responsibility of the customer to ensure that only
authorized persons may be allowed to use the PGK.
The user
- is qualified and properly instructed and has the necessary
experience.
- knows the relevant standards, accident prevention rules
and operating conditions.
- is able to carry out the necessary operations and is aware of
the possible dangers involved.
- must immediately inform his superior about any conditions of
the unit that could affect safety.
-The High Voltage Testing Sets PGK50 and PGK80 are
exclusively for testing the dielectric strenght of electrical
equipment with a maximum capacity of 20 µF.
Any other or additional use is deemed to be in contravention of
the intended use. The manufacturer shall not be liable for
damage resulting from any such use. In such a case the risk
shall be borne solely by the user.
The local safety and accident prevention regulations are
always applicable to the operation of the PGK50 and PGK80.
Please read now
and avoid damage
and injury later!
Only authorized personnel!
Use the PGK50
and PGK80 as directed!
☞
At the customer’s written request we undertake to repair or replace
at our discretion and as quickly as possible all parts that become
faulty or useless as the demonstrable result of poor material, faulty
design or defective execution.
The 12 month warranty time starts with delivery.
We shall bear the costs of any faulty parts requiring replacement,
but not the costs of transport to us and back to the customer, nor the
costs of packing and insurance! We shall not be liable for any
damage resulting from normal wear and tear, improper handling,
non-observance of Operating Instruction and safety regulations.
We shall also refuse to accept any liability if the customer carries out
repairs or changes to the unit himself or has others carry out them!
The warranty does not cover damage in transit, batteries, fuses and
any readjustments in accordance with the Operating Instruction!

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

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.

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.
