3. Preparations for a Test
Connect test object
Test configuration A and B must be
strictly adhered to!
The current measuring section of the PGK has an available test
range of 10µA to 100 mA.
Test configuration A for test current ranges of 10µA to 100mA.
Test object is earthed!
Test configuration B for test current ranges of 1µA to 100mA.
Test object is isolated!
☞
Important:
The described procedure for test configuration A and B must
be strictly adhered to!
The local safety and accident prevention rules apply!
Continued
For test current ranges of 10µA to 100mA. Test object is earthed!
In test configuration A all secondary output currents will be
registered. At voltages higher than 10kV corona and insulation
currents of the PGK of with more than 100nA may occur. These
currents will be registered during the return flow from the high
voltage source to the current measuring device.
