The need for the current waveform to track the voltage on a three-phase power system leads to a second set of requirements, in addition to those for a single-phase power factor correction (PFC) system ...
If it's a true three phase system, it should have a third rail that will zap if you if you touch it and and ground. It's 3x zap and a ground, where two of the electrified lines are overhead and one ...
