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 14, connect the 2kV output socket without point to the
transformer’s secondary (1S1) winding connection, and the output socket
marked with a point to earth and the transformer’s primary connection (P1).
Warning: be aware that the terminal that is connected to the transformer’s
secondary connection "1S1" leads life-hazardous voltage!

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.
