Lightning arrester: An electrical device used to protect electrical equipment from the hazards of high transient overvoltages caused by lightning strikes, while also limiting the duration and often the magnitude of any follow-current.

Overvoltage Protection
Atmospheric overvoltage: Generated by direct lightning strikes or electromagnetic induction, these surges can reach voltage levels of several million volts. Lightning arresters rapidly conduct and discharge the lightning current, thereby limiting the voltage that equipment insulation must withstand.
Overvoltage due to switching operations: Caused by circuit breaker operations, system faults, and more, surge arresters suppress voltage surges, safeguarding equipment from sudden impacts.
System Stability Assurance
Avoid overvoltage that could lead to equipment insulation damage, short circuits, or power outages, ensuring the safe operation of key plant and substation equipment, such as transformers and circuit breakers.
