Surge Arrestors stand as a sentry, at the entry point of transmission lines and expensive equipment like transformers and shunt reactors. They perform the task of protecting these equipment and ensuring safety under adverse conditions such as lightening impulses. It is very essential that the arrestors perform correctly because they have a tendency to fail violently resulting in large scale damage to neighboring equipment like CTs, CVTs and CBs. 

SCOPE's SA series is designed to analyze the performance of the surge arrestors and ensure such failures are avoided.
