Current Transformer
4 - 25
Voltage Withstand Test
Use the test card
VWithstand
to measure the voltage withstand capability of the
secondary winding and secondary wiring.
To do so, disconnect the burden. As shown in Figure 15, connect one cable of
the 2kV output to the transformer’s secondary (1S1) winding connection and the
other cable to earth and the transformer’s primary connection (P1). Open the
secondary ground connection and ground the burden for safety reasons.
Warning
: be aware that the terminal that is connected to the transformer’s
secondary connection "1S1" leads life-hazardous voltage!

Setup for a voltage
withstand test
Note:
Some test cards are available in more than one test mode. For
example, the test card
VWithstand
can be selected in CT, VT,
Resistance and Transformer.
This is solely related to usability. With regard to functionality, the test
card
VWithstand
is identical in all test modes.
