How to Reduce Harmonic Distortion in VFD Systems Variable Frequency Drives (VFDs) help factories control motor speed and reduce energy consumption. However, they can also introduce harmonic distortion into the electrical network. When several drives operate together, these harmonics can increase transformer heating, overload cables, and affect sensitive equipment. Reducing harmonic distortion in V...
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...
