Enhancing The Lightning And Overvoltage Resistance Of Electrical Systems Through Surge Arresters

The working mechanism of 11kv lightning arrester is different from that of ordinary protection devices. It uses the nonlinear material characteristics to provide a low-resistance path when the voltage exceeds the set threshold, and directs the transient voltage pulse to the grounding system. In this way, high-amplitude overvoltages will not enter the sensitive components along the circuit.

In power distribution and transmission networks, a well-planned 15kv lightning arrester protection device can form multiple layers of protection near power lines, transformer terminals, and major switching equipment. This allows for rapid diversion of lightning energy when the power system suffers induced lightning strikes or system switching overvoltages.

The configuration strategy for lightning arrester in transformer varies depending on the voltage level and environmental conditions. The selection should be based on the system's rated voltage and the maximum overvoltage amplitude that may be encountered.
