    I am trying to source a coil which has got very little details on it

    I would like some help in identifying and sourcing a coil. I have never seen one like this and there is very limited markings on it. 17-5509 Y7 is marked on one side and all I can make out from the label is Coil 240v 50hz.

    Earthing neutral in a multi source system

    This has me clueless. Why must the neutral be unearthed at the transformer and generator and only allowed earthing at the switch-gear? I can't see any reason because the neutral will normally not be carrying any current and thus no parallel current paths would form.
