sf6 emissions Maintance for 400kv

Sep 05, 2019SF6 is an electronegative gas and it has the tendency to absorb free electrons. Breaker contacts are opened in the high-pressure flow of SF6 gas and an arc is struck between them, free electrons in the arc are quickly captured by the gas so that it can form immobile negative ions and this loss of conducting electrons in

    A typical Dew Point value for Tropical country like India, of - 37 0 C (180 PPMV) measured at atmospheric pressure is most satisfactory favoured for SF-6 breakers up to 400Kv range, since this value is to - 15.90C at breaker operating pressure of 7 Kg/cm2, which is well above lowest operating Temperatures in India. From this point of view, lowest acceptable Dew Point of - 300C (375 PPMV) can be fixed as a Danger Monitoring parameter, since it corresponds to - 80C Dew
