Arc suppression coil control panel is a kind of equipment specially used for controlling and managing arc suppression coil in power system. Arc suppression coil is an inductance coil with iron core, which is connected between the neutral point of transformer (or generator) and the Earth, forming the arc suppression coil grounding system.When the arc suppression coil controller is correctly tuned, it can effectively reduce the probability of generating arc grounding overvoltage, and at the same time, it can effectively restrain the radiation value of Overvoltage and Prevent Overvoltage from causing damage to power grid equipment.By reducing the current at the fault point and suppressing overvoltage, arc suppression coil controller helps to protect the equipment and lines in the power grid and prevent more serious power grid accidents caused by single-phase grounding fault.The use of arc suppression coil controller can reduce the power failure time caused by single-phase ground fault an…
