  • Leak Testing High Voltage Switchgear - LACO Technologies

    May 14, 2015 · Gas-insulated high voltage switchgear typically use a sulfur hexafluoride (SF6) gas to minimize arcing when the circuit breaker is activated. Leak testing of the subassemblies and finished product provide confidence that the sufficient pressurized SF6 gas will be contained inside the unit to prolong its functional life.

  • 34 Questions And Answers To Break the - SF6 gas leak detector

    For HV switchgear the emission factor ranges from about 0.1% per year to 0,5% (0,5% per year is the maximum acceptable leakage rate according to IEC 62271-203) For sealed for life MV equipment a range below 0,1 % per year is common. For example, a 3 kg filling quantity (RMU) results in a calculated loss of 3 g per year.
