generally two types of CT are used 1) Window type 2) Bar
type.
1) in window type ct are used in HV voltage level there
equipotential wires are used. in window type ct conductor
passing through it so stress on CT materail is uneven so
that it create more stress near conductor and less on other
parts. so CT is desing such a way that onother layer
provided in ct and conducting path provided and busbar
connected to this conducting parts so that potential of
entire Window ct inside surface is equal and stress on CT
is eliminated.
