why we do 2 types of earthing on tranformer ie:body earthing
& nutral earthing , what is function.
i am going to instal a 5oo kva tranformer & 380 kva DG set
what should the earthing value
Answer Posted / kunwar singh
Body Earthing : To ground any leakage current flowing in the e body of transformer & to protect human Body.
Neutral Earthing: To ground the unbalanced current in neutral.
The earth resistance should be below than 2 ohms.
