Surge Protective Device Failure Modes, Impact and Corrective Actions

Abstract

Surge protective device (SPD) is used to protect electrical and electronic devices from the transient over voltages(surges). Failure occur in SPD effect on the expected performance of overall protection system. A more thorough understanding of all possible SPD failure modes is important for system protection. The main motive of this paper is to provide the reader with principles of SPD failure and effective corrective action.
