MOT current draw question
Original poster: "Marry Krutsch by way of Terry Fritz <twftesla-at-qwest-dot-net>" <u236-at-earthlink-dot-net>
Hi all.
I just got a new current xfmr, and used it to measure the current draw
on all my HV xfmrs. My copier trannies measured acuratly at 8.4 amps,
but my MOTs were a different story. According to the current xfmr and
Fluke meter they pull between 20 and 40 amps! That can't be right,
since I did the test on a 15 amp breaker which is supposed to trip at
17.5 amps. What is happening? How can I get an accurate measurment?
Thanks,
Winston K.
