Medium

Function of Medium Voltage Surge Arresters

The surge arrester acts as an insurance mechanism that ensures equipment is protected from voltage spikes exceeding their voltage rating, thereby reducing the risk of equipment failure and associated costs. The proper sizing and installation of the medium voltage surge arrester are essential for its efficient and effective operation.

Medium voltage surge arresters are commonly used in a variety of applications, including power distribution systems, industrial facilities, and commercial buildings. They are installed to protect equipment such as transformers, switchgear, motors, and other medium voltage electrical components from voltage surges or transients caused by lightning, switching operations, or other sources.
