Analysis of Parameters and Time Sequences for Full Operation Mode of Vacuum Interrupter for Medium Voltage Power Plants

Abstract

Parameters of a vacuum interrupter are essential. Although most of researchers and industries are involving metallurgy by using a refractory materials "alloys" electroplates for vacuum interrupter for the sake of sustainable materials against both arcing current, chopping currents and disruptive over voltages. This paper addresses the description of all parameters and evaluates switching processing times for three circuit breakers, VD4 /ABB Vacuum type 6.6KV/1500A/20KV/40KV-IEC60-071 " for maximum switching times 2.7ms" . Three synchronous generators 6.6KV/8MW each have been connected to three power transformers, rating 6.6KV/1250KVA in refinery power plant.
