Surge Arrester

A surge arrester is a device used in electrical systems to protect equipment from voltage spikes caused by lightning strikes or switching operations. It works by providing a safe path for excess electrical energy to flow into the ground, preventing damaging high voltages from reaching sensitive components. Surge arresters are typically installed on power lines or near electrical equipment and act quickly to clamp or divert large surges, maintaining system stability and safeguarding electrical devices. They are essential for ensuring reliability and preventing costly damages in electrical infrastructure.
