  • 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.

    Sep 17, 2019 · When the test is started, high voltage DC is applied to the VI and the baseline leakage current is measured. Next, a DC voltage pulse is applied to the magnetic field coil during a second application of the high voltage DC and the total current is measured during the pulse. The ion current is calculated as the total current minus the leakage current.
