Why are surge arresters important in electrical distribution systems?

Surge arresters play a crucial role in electrical distribution systems by protecting equipment and infrastructure from voltage spikes and transients caused by lightning strikes, switching operations, or faults. These surges can result in significant damage to sensitive electrical components, leading to costly repairs and downtime. By clamping down excess voltage and redirecting harmful surges to the ground, surge arresters help ensure the stability and longevity of electrical systems. This protective function is essential for maintaining both safety and functionality in the electrical grid, thus supporting reliable power delivery to consumers and industries alike.
