  • High Voltage Switchgear SF6 Maintenance

    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 required by law in the European Union, under the Kyoto Protocol, to monitor vessel top-off and leakage.
