What is C.T, why it is used and what care should be taken
for that while connecting?
Answer Posted / vikas tiwari
CT means Current Transformer, It is used to measure the
higher value current flowing through the circuit.
CT should be connected in such a way that the current
should enter from the P1(primary) & leave from P2, Also on
secodary side S1 & S2 should be connected with correct
sequency other wise the meter will not sense the current,
While CT is not in use, we should short the S1 & S2
(Secondary) of the CT to avoid saturation of the CT.
If the seconday of loaded CT will be kept open it will get
saturated & burst
