Does a 3 phase motor need a neutral
WebJul 30, 2024 · Does a 3 phase contactor need a neutral? In a 3 phase system, a neutral fault could leave an element with the best part of 400V across it, if highly unbalanced … WebLarge three-phase motors and the equipment they drive should consume power equally from each of the three mains phases. However, that often doesn’t happen. Unbalance and harmonics can cause instability, with …
