Protection and Switchgear - SlideShare

Sep 06, 2015 · Sulfr hexafluoride CIRCUIT BREAKERS It contains an arc interruption chamber containing Sulfr hexafluoride gas. In closed position the contacts remain surrounded by sf 6 gas at a pressure of 2.8 kg/cm2 . During opening high pressure Sulfr hexafluoride gas at 14 kg/cm2 from its reservoir flows towards the chamber by valve mechanism. sf6 gas rapidly absorbs the free electrons in the arc path to form immobile negative ions to build up high dielectric strength. It also cools the arc and extinguishes it. After operation the valve is closed by theGet price

Transformer dew point measurement insulation moisture 1 | TD

Feb 01, 2014 · A traditional method to measure dew point is a chilled mirror instrument where the mirror is cooled down until dew forms. The dew formation causes light to be scattered on the surface, which is detected with optics. At the start of dew formation, the temperature of the mirror denoting dew point is read by a thermometer.Get price
