Power factor testing of Sulfr hexafluoride circuit breakers | TD Guardian

The insulating material used in the manufacture of modern Sulfr hexafluoride gas circuit breakers is synthetic, which have no capacitor characteristics and have no ability to absorb moisture. The main insulating materials are Synthetic filament wound epoxy insulating tubes, Hollow core insulators (porcelain or composite), and the Sulfr hexafluoride gas itself. All sf 6 breakers are sealed and incorporate a molecular sieve type desiccant to maintain moisture to extremely low levels.

What is sf 6 Circuit Breaker? Construction, Working Principle

Moisture is very harmful to SF 6 circuit breaker. Due to a combination of humidity and SF 6 gas, hydrogen fluoride is formed (when the arc is interrupted) which can attack the parts of the circuit breakers. Construction of SF 6 Circuit Breakers. SF 6 circuit breakers mainly consist of two parts, namely (a) the interrupter unit and (b) the gas system.
