  • high-voltage 160 switchgear check for leaks

    high-voltage 160 switchgear check for leaks. In this article we will cover production leak testing of gas insulated high voltage switchgear and associated subassemblies. Gas-insulated high voltage switchgear typically use a sulfur hexafluoride (SF6) gas to minimize arcing when the circuit breaker is activated.
