Harmonic filter

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.

Zero-Sequence Harmonic Filter
As the spread of single-phase nonlinear loads such as computer loads and electronic fluorescent lamps is spreading, damage to electrical equipment such as overheating of distribution lines and malfunctioning of circuit breakers and relays is reaching a serious level due to the zero harmonic current of the neutral line. Since ZSF (Zero Sequence Harmonic Filter) is a semi-permanent filter designed and manufactured by minimizing the zero-sequence impedance, it can maintain its performance at any lo
