1. The PE line is the protection zero line or the protective ground line;

2. If your system is an IT system, the PE line is the protective ground line;

3. If your system is a TN system, the PE line is the protection zero line;

4. The neutral point of the transformer is an ungrounded system. The metal casing of the electrical equipment should be protected from grounding, that is, the protective grounding system is represented by IT;

5, the neutral point of the transformer is the grounding system, the metal casing of the electrical equipment should be protected to zero, that is, the protection zero system, represented by TN;
