    Exploring SF6/N2 mixed gas : advantages, applications, and analysis

    SF6/N2 mixed gas is a widely used insulation medium in the power industry. In traditional GIS (gas insulated switchgear), SF6 gas has always been used as an insulation medium, but due to its high global warming potential, SF6 is gradually receiving attention. In contrast, SF6/N2 gas mixtures have...

  • How to test whether the motor winding is grounded

    How to test whether the motor winding is grounded

    When the windings of the motor short circuit to the ground, short circuit to each other or open the circuit (that is, the winding wire breaks), the motor will fail. The wires in the winding use an insulating covering as an isolation barrier. If the insulation layer of the winding is worn near the...
