Surge arresters are composed of a series of metal oxide varistors (MOVs) that are connected in parallel and housed inside a porcelain or polymer housing.
Surge arrester, also known as lightning arrester, is an electrical device used to protect electrical systems and equipment from voltage surges caused by lightning strikes or switching operations.
Surge arresters are composed of a series of metal oxide varistors (MOVs) that are connected in parallel and housed inside a porcelain or polymer housing. When a voltage surge or lightning strike occurs, the MOVs conduct current and divert energy to ground, thus reducing the voltage across the protected equipment to a safe level.
We offer both distribution and transmission surge arresters.
