Abstract

Field measurement and computer analysis concerning 150 MVA shunt reactor current interruptions at a 275 kV gas insulated substation (GIS) were carried out to verify that high-frequency current interruptions can be caused by certain system structures on the circuit breaker power supply side. A shunt reactor current-interrupting test was conducted with phase angle control, which is considered to be the best method for preventing multiple reignitions, using short-circuit test facilities. The possibility of stable reignition-free interruption was confirmed, even when the longest arcing time is preset
