I need some advice what need to do for maintenance if motor run at current >3% derating…
Either need check the looseness, swap phase cable to verify or else.
Need someone to advise.
Tq.
My guess, he’s asking about an imbalance in currents drawn by a 3-phase induction motor. Basically, the currents should sum to zero, but often they don’t.
Anyway, if it’s only a 3% imbalance, that’s nothing to be concerned with. Oh, and this is entirely the wrong forum for this question.. 🙄
