Wound Primary Type :
When
the ratio is low it becomes difficult to obtain good results with the
single primary turn. For that purpose wound primary CT’s are used where
both primary and secondary turns are wound on the torroidal core. The
ranges available are from 5/5A to 100/5A. Also Secondary 1A can be
provided. Optional mounting arrangements are provided as the CT is
mounted between two bakelite plates and brass terminals are provided
for connections of primary & secondary.
