Abstract :
A 150 MVA reactor current interruption test using a GIS (gas-insulated switchgear) on an actual 275 kV cable system and a laboratory high-frequency current interruption test using a 300 kV SF 6 gas circuit breaker were conducted. The results of these tests and their analyses, made simultaneously, permitted (1) the calculation of reignition surges and the detection of high-frequency arc extinctions caused when the reactor current was interrupted by a GIS on a cable system and (2) an evaluation of voltage escalation caused at high-frequency arc extinctions
