Working Principle Of Three-stage Lightning Arrester

The third-level 132 kv lightning arrester is mainly used to protect terminal equipment from low-intensity surges or damage caused by lightning-induced currents. This level of 132kv lightning arrester is usually installed close to the terminal equipment and can further reduce the residual voltage to a safe level that the equipment can withstand after the first two levels 132kv surge arrester reduce high-energy surges.
