Winding Resistance
Never open the measuring circuit while current flows. Dangerous voltage may
occur!
Figure 6:
Setup for a winding
resistance test
Use the RWinding test card to measure the resistance of a current
transformer’s secondary winding.
To do so, open the circuit as shown in Figure 6, loop the I DC current signal from
CPC 100 6A DC output via IAC/DC or directly from 400A DC output, and inject
it into the transformer’s secondary winding.
Note: Some test cards are available in more than one test mode. For
example, the test card RWinding can be selected in CT, Resistance
and Transformer.
This is solely related to usability. With regard to functionality, the test
card RWinding is identical in all test modes.
