    Bias magnetic arc suppression coil is currently an advanced control principle arc suppression coil equipment. By arranging a magnetized iron core section inside the arc suppression coil, adjusting the DC excitation current to change the magnetic conductivity of the iron core, thereby achieving continuous and adjustable inductance. When the system is operating normally, the arc suppression coil operates far from the resonance point. When a single-phase grounding fault occurs in the power grid, the system can instantly adjust the inductance and compensate for the grounding capacitance current. The bias magnetic arc suppression coil has a long service life, is maintenance free, and this adjustment method can be free from the constraints of load switches, with a larger compensation range, fast capacitance current measurement speed, and fast and accurate compensation. Therefore, the bias magnetic arc suppression coil is very suitable for industrial and mining enterprise users whose system operation mode often needs to be adjusted.
