help plz neutral harmonics
(OP)
I monitored a commercial building for one week and the harmonics (neutral) result as:
THDv(N)=31.2% && 3rd harmonic=21.89%
THDi (N)= 194.4% && 3rd harmonic= 186.8%
could anyone tell me what are they mean and how to mitigate them..
thanks

RE: help plz neutral harmonics
The percentage is not a problem. The question is how many amps you measure in the neutral. Of course, if you got 32% THDv, it doesn't look good.

Half full - Half empty? I don't mind. It's what in it that counts.
RE: help plz neutral harmonics
the maximum amps in neutral is about 150A at rush work hour
