Test Method of sf 6 Relay in Low Temperature and Extreme

During the inspection, it was found that the temperature value read by the system after adjustment was -33°C instead of -40°C. The reason for this phenomenon is that sf6 gas gas will liquefy as the pressure rises, and then release a certain amount. The heat makes the test temperature near the gas path higher than the adjusted temperature.Get price
