Induction Furnace Harmonic Mitigation: AHF & SVG Guide Medium-frequency induction melting furnaces and electric arc furnaces (EAF) are core assets in modern metal foundries, steelworks, and precision casting facilities. However, their high-power silicon-controlled rectifier (SCR) and insulated-gate bipolar transistor (IGBT) front-ends act as intense sources of non-linear electrical distortion....
Power Quality in Cold Storage Facilities: How AHF and SVG Protect Refrigeration Systems In modern cold chain logistics hubs, pharmaceutical storage warehouses, and food processing facilities, refrigeration infrastructure is a continuous, mission-critical operational lifeline. Facility operators rely on multi-stage ammonia and Freon screw compressors, evaporative condenser fans, secondary glycol ci...
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...
