Due to the development of power electronics control technology, the use of three-phase nonlinear loads (inverters, SCR heaters, UPS, etc.) and single-phase nonlinear loads (lights, electric heat, computers, OA equipment, etc.) is rapidly increasing.
Harmonic currents and voltages generated from these loads may cause deterioration, burnout, and reduced lifespan of transformers, cables, and circuit breakers, and may cause major disturbances such as device malfunction and system downtime.
