The distribution line of the power system is grounded through an arc suppression coil, which is a type of low current grounding system. When a single-phase short circuit fault occurs, the inductance current flowing through the arc suppression coil and the capacitance current flowing through it add up to the current flowing through the short circuit grounding point. The phase difference between the inductance and capacitance is 180 degrees, and they are mutually compensated. When the magnitude of the two currents is less than the minimum current at which an arc occurs, the arc will not occur and resonance overvoltage will not occur. This is often the case for power lines with a voltage level of 10-66KV
