How is a 380V system grounded?
Thread Content
Are there any models that can operate at 380V with ungrounded connection? For 380V ungrounded systems, if one phase in a circuit becomes grounded, how can the grounding point be located quickly? Is there any equipment that can help with the search, and is it effective? Thank you
I’m an amateur; I’m sending a reply to ask for guidance. For 380V systems without grounding, simply using an isolation transformer would solve the problem. Also, in the case of a short distance between one phase and ground, could another phase be used to connect a galvanometer for measuring the current against ground? The greater the current, the closer the distance is
