Smart Surge Arresters: Revolutionizing Overvoltage Protection

Line surge arresters (LSAs) are the workhorses of overvoltage protection in power grids, safeguarding equipment from damaging voltage spikes caused by lightning strikes and other transient events. Traditionally, LSAs have been passive devices, offering reliable protection but lacking the ability to provide insights into their health or the surge activity they experience. However, the integration of monitoring and diagnostic features into LSAs, creating "smart" surge arresters, is revolutionizing overvoltage protection strategies. This article explores the development of smart LSAs, discussing their monitoring capabilities, diagnostic features, and the benefits they offer for proactive maintenance and optimized performance.
