In low voltage power system, harmonic currents can occur from rectifiers and some others electrical componets. I have found a formular for k-faktor derating of transformers when harmonic currents is present. What about deratings for 4 wire cables and synchronous generators (about 1000kVA, 400V)?
And the 2. question:
In low voltage system where harmonic current is present=85, how will the harmonic current flow in the system and how do harmonic currents generate from deferent devices interact with each other?
I hove some one out there can help me...
