Hi all,
Im still in apprentice stages of becoming a sparky and currently learning allot about 3 phase at college the moment. Can anyone share their knowledge with me on how to correctly calculate the Neutral current on a 3 phase 4 wire star system when there is an imbalance between phases
e.g L1 = 50 amps, L2 = 40amps, L3 = 30amps?
Im a bit unsure on the correct way to calculate the Neutral current.
Thanks for your time and help.... Please be gentle I'm still learning
