Does a transformer require 2 grounding PE wires?
Transformers require 6 grounding PE wires; generally, 1.2 are used for grounding on the high-voltage side； 2.4 High-voltage side grounding PE ；
Transformers require 6 grounding PE wires; generally, 1.2 are used for grounding on the high-voltage side； 2.4 Low-voltage side grounding PE ； I’m sorry; I wrote low voltage instead of high voltage
I don’t understand how to connect those 6 radicals The three-phase grounding method is also widely used in 10/0.4 KV systems; there are no 6 wires either. Hope for assistance
It seems that a transformer should have two grounds, independent of each other.
I don’t understand; the transformer housing I made, which is 800 units in size, is welded to a foundation, and that foundation is connected to the ground； The high-voltage side is grounded to the foundation, while the low-voltage side and N are both grounded to the foundation. I’m not sure if it’s appropriate?
It depends on the grounding type of your power system: TN-S, TN-C, TN-C-S, TT systems, IT systems. It can’t be generalized.
It depends on whether your transformer has 3 wires, 4 wires, or 5 wires
