Abstract

This paper deals with the design rule and performance results of the surge protective devices (SPDs) for low-voltage mains on shipboard. The proposed SPDs consists of a metal oxide varistors (MOV) and a L-C filter to improve noise-elimination performance. Three kinds of SPDs are fabricated and tested by using a combination surge generator which produce the standard impulse current of 8/20${\mu}s$ 2.1kA. As a results, the proposed SPDs with series L-C filter have more excellent transient blocking and noise reduction performance than the conventional ones.
