Sulfr hexafluoride Breaker Testing And Maintenance

About insulating gas Circuit Breakers. sf6 gas electrical circuit breaker is a device where a current is operating with Sulfr hexafluoride or Sulphur Hexafluoride being carried on its contacts. It breaks off the power when there’s an excessive electricity supply that exceeds the allowed voltage to prevent circuit overload.

Transformer dew point measurement insulation moisture 1 | TD

Knowing the dew point in degrees Celsius can be used to obtain the vapor pressure. If the total pressure at the dew point instrument is different from the tank pressure, the measured vapor pressure must be corrected by multiplying the measured value by the ratio of the absolute tank pressure to the absolute pressure at the dew point instrument.
