All aux. Neutral and body is connected to earth. If the connected load is healthy then the voltage between neutral and earth should be zero. If due to any of aux. fault or due to improper connection of earthing or imbalnce load the voltage between neutral and earth increases and it's not app zero varies at various locations if various aux are connected on same earthing in that case earthing is said to be floating .

what are the standard IR values should be of R-E, Y-E, B-E, R-Y, Y-B, B-R of VCB in closed condition and in open condition for 500KVA & 1000KVA transformers. and what is the acceptable range when tested by 5000V megger.

How do i perform grounding of star point of Genset (400V) for making connection with step up transformer of DELTA-DELTA (400V to 20KV) ? while Genset itself has its own neutral and grounding bus bar inside genset breaker box whereas we have another neutral and grounding busbar in synchronizing panel next to genset at maximum distance of 6meter, would someone pls advice if we can only perform neutral grounding in synchronizing panel or should we ground neutral on both places inside genset breaker box and synchronizing panel.
