The core structure of the arc suppression coil is improved to solve the nonlinearity of voltage with zero-excitation. The harm of ferro-resonance is thus reduced.
PT breaking and ferro-resonance caused by single-phase grounding and PT saturation are common faults in medium-low voltage power networks, which make voltage abnormal.
