Answer Posted / abdul moin
when a CT in connected to the transformer is for the
current reading to know the amps folowing through the
conductor. we keep the terminal close because of the
secondary side voltage will be rise. thats why when we
remove the meter for the maintenance purpose we provided a
short link for close the terminals inorder to avoid high
voltage at secondary.
i Hope this answer is satisfy you......

Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short.
