What Causes Neutral Current in Three-Phase Systems? Neutral current in three-phase systems is a common power quality concern in factories, commercial buildings, and data centers. In a balanced electrical system with linear loads, the three phase currents cancel at the neutral point. However, uneven loads and harmonic distortion can cause significant current to flow through the neutral conductor. E...
