Transformer
*) Due to cross-talk between the measuring inputs
V1 AC
and
V2 AC
, we suggest not to connect
a current clamp to the input
V2 AC
. Therefore, use a current clamp with current output.
This test is identical to the voltage withstand test described on page Current Transformer-4.
This test is identical to the polarity check described on page Current Transformer-5.
