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

    Mar 20, 2013Due to its low gaseous viscosity, SF6 gas can efficiently transfer heat by convection. So due to high dielectric strength and high cooling effect, SF 6 gas is approximately 100 times more effective arc quenching media than air.. Due to these unique properties of this gas, SF6 circuit breaker is used in a complete range of medium voltage and high voltage electrical power system.

    Jun 12, 2012Gentlemen, let me disagree with you.Lightning impulse test is not a destructive test and repetition of it will not reduce insulation life.None of the dilelectric tests are overstressing insulation.It is only checking whether the insulation can withstand the margin of additional stress over normal working stress as required by standards.It is designed for these overvoltages.
