measure the three phases of one set of parallel conductors ?
measure the three phases of one set of parallel conductors ?
(OP)
Hi Everyone,
I use a three-phase power quality meter to check for power problems in commercial facilities.
Many times to measure the current on larger switch boards is impossible with clamp on current transformers and is even sometimes impossible with the flex CTs, because of the many parallel conductors.
If I measure the current of the three phases of one set of parallel conductors will I get true waveform and other quality related measurements?
Is this an acceptable practice?
This would make my life much easier.
Thanks,
Andy

The IR scan is a good idea, or you can check the current in each conductor with your clamps to assure yourself that current is splitting roughly equally.
