Long Duration Current Impulse Withstand Test on Metal Oxide Surge Arresters: A Straightforward Procedure

摘要

The testing procedure for long duration current pulse withstand tests on metal-oxide surge arresters has been largely treated. This paper describes a new test method based on the fact that the volt-ampere characteristics of the arrester do not change from shot to shot, since temperature changes do not practically affect these characteristics in the range of interest. The aim of the method is to simplify the test procedure and to test the samples with stresses closer to the actual system reality. This procedure had been submitted for discussion to the relevant technical committee of the International Electrotechnical Commission and should form an Appendix of the Standard Draft on metal-oxide surge arresters.
