What is the arrester?

Surge arrester, also known as: surge arrester, can release lightning or can release power system operation over-voltage energy arrester, also known as: surge arrester, can release lightning or can release power system operating over-voltage energy, protect electrical equipment from transient over-voltage hazard , can also cut off the freewheeling, electrical equipment that will not cause the system to be shorted to ground. The arrester is usually connected between the live conductor and the ground in parallel with the protected equipment. When the overvoltage value reaches the specified operating voltage, the arrester acts immediately, flows the electric charge, limits the overvoltage amplitude, and protects the equipment from insulation. After the voltage value is normal, the arrester quickly returns to its original state to ensure normal power supply.
