  • High Voltage Switchgear SF6 Maintenance

    Unfortunately, SF6 is a costly, maintenance intensive and potentially environmentally damaging solution. Over the years, installations have started to show signs of SF6 breakdown, decomposition and leakage. Given the fact that SF6 is also a potent greenhouse gas, 22,000 times more dangerous to the ozone layer than CO2, power companies are now

    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.

    Sep 20, 2019Why worry, leaks!. The discovery of SF 6 can be traced to the work of Henri Moissan and Paul Lebeau in 1901, who found that sulfur reacted with fluorine according to the reaction equation: . S 8(s) + 24 F 2(g) → 8 SF 6(g). Under ambient conditions of temperature and pressure, SF 6 exists as a gas; this property is traceable to the small size and low polarizability of the fluorine atoms
