Empirical Performance Test of SPDs used in Communication Networks

통신용 SPD 성능평가를 위한 실증시험

The purpose of this paper is to identify the requirements for Surge Protective Devices (SPDs) used in protecting telecommunication and signalling system. All of these systems may be exposed to the effects of lightning and power line faults, either through direct contact or induction. These effects may subject the system to overvoltages or overcurrents or both, whose levels are sufficiently high to harm the system. SPDs are intended to provide protection against overvoltages and overcurrents caused by lightning and power line faults. This paper describes tests and requirements which establish methods for testing SPDs and determining their performance.
