    2 Moisture values can be interpreted in several units; parts per million by volume (PPM v), parts per million by weight/mass (PPM w or PPM m), dew point (C& or F&), and relative humidity (RH). Decomposition Although SF 6 is non-toxic in its pure form, it will decompose when exposed to high temperature or electrical arcing – especially in the presence of moisture.

  • SF6 Circuit Breaker: What Are They? (Types and Operation

    Mar 20, 2013An SF6 circuit breaker is a type of circuit breaker in which sulphur hexafluoride gas or SF 6 gas is used as the arc quinching medium, known as an SF6 circuit breaker. SF 6 gas has excellent insulating property and it has a high electronegativity. Due to high electronegativity, it has a high affinity for absorbing free electrons.
