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...Read more -
What causes the current transformer to burn out
?HV HIPOT GDHG-306D? CT/PT Analyzer The first reason is that the secondary side of the current transformer is caused by an open circuit due to weak wiring In the process of using a current transformer, if the secondary side opens due to wire disconnection, the current will be equal to ze...Read more -
