Mikrosensorik SF6 Breakers Measurement

Mikrosensorik SF6 Breakers Measurement

The dual pressure breakers (typically applied at 230kV and above) had a dielectric system pressure of approximately 40psig. They utilized a compressor arrangement to pressurize the arc extinguishing SF6 to a pressure of gas to enable multiple operations of this style of circuit breaker.
