What is a harmonic filter resistor?
A harmonic filter resistor is a critical component in harmonic filter systems, designed to withstand fault currents up to 200 amps and operate over a wide voltage range (1 to 132 kV). This resistor ensures stable operation of industrial power systems by reducing harmonic distortion.
