500kV Sulfur Hexafluoride Stress wholesale

High voltage laboratory tests on a 500 kV SF6 circuit breaker are discussed and analyzed in terms of insuring effective insulation coordination on a live tank breaker for either 1550 kV or 1800 kV BIL service. Sixty cycle, impulse, switching surge, and corona level tests were made at minimum operating (alarm) pressure. Additional tests at 0 psig revealed a 60 cycle withstand in excess of twice
