Potential difference between zero and ground in the TT system
Hello, please tell me if there can be a potential difference between protective ground and a working zero in the grounding system of the CT type. If so, how can this difference be avoided?
Hello! Maybe if zero on the high-voltage power line is in poor condition, there are no repeated grounding, etc. Why avoid it? Are you going to touch several live parts at the same time? To avoid, you need to ground zero. For example, under support from where the input is made. Even the PUE recommends doing so.
