Is there any potential hazard in bringing the neutral of several 11kV/400V Dyn11 transformers to a common earth bar and then connecting to the earth pits?
I am a bit concerned if there could be any circulating current between the transformer neutrals or if there could be a chance of raising the potential of star point of any transformer due to an earth fault in some other transformer. Any suggestions in this regard will be highly appreciated.
