A transfer lightning arrestor (also known as a transfer surge arrester or transfer type lightning protector) is a device designed to protect electrical systems and equipment from lightning-induced surges by safely transferring excessive voltage from one line or phase to another, or to the ground.
Description:
The transfer lightning arrestor is typically installed between phases or between phase and neutral in an electrical distribution system. When a lightning surge or transient overvoltage occurs, the arrester provides a low-impedance path that allows the surge current to transfer away from sensitive equipment. After the surge passes, it automatically returns to its normal high-resistance state, maintaining normal circuit operation.
