50 vs. 60 Hz electro-mechanical 50/51 calibration
50 vs. 60 Hz electro-mechanical 50/51 calibration
(OP)
I've noticed some electrical-mechanical overcurrent(50/51) relays labeled 50/60 Hz and others labeled 60 HZ. We have been requested to calibrate several relays for 50Hz operation. Is there a consideration for 50 vz 60 Hz calibration of the same relay? We are in a 60Hz country.
Thank you.
Thank you.
