What is C.T, why it is used and what care should be taken
for that while connecting?

Answer Posted / manoj patel

It is called as current transformer which is used to
transform higher range of current to lower range. It's
output is used as an input to protection circuit and
mearsuring instruments as the protection circuit and
measuring instruments are designed for lower range of
currents.
Care taken....If ther is metering core then all metering
instrument must be connected in series of S1 & S2
terminal.Same for protection core.
If there is single core CT then whenever its secondery is
not in used it should be shorted.
