11/0.4 kV transformer neutral earthing
11/0.4 kV transformer neutral earthing
(OP)
1500 kVA transformer, 11/0.4 kV Dyn11 installed in a substation
what is the standard or practice for earthing the LV side neutral point ?
is it required that the neutral point should have a separate earthing point/system or it can be connected with the substation earthing system?
what is the advantages, and disadvantages in both cases (separate earthing or earthing with the substation earthing)?

See Table 2 Minimum requirements for interconnection of low voltage and high voltage earthing system based on EPR limits.
Following Annex A and B one may calculate the touch voltage.
The lightning protective grounding it is recommended to be connected with the substation grounding grid .See Annex F for further details.
