What is C.T, why it is used and what care should be taken
for that while connecting?
Answer Posted / vijaykumarht
CT means current transformer which is used to measure high
currents in terms of very low voltage. And this is converted
into current with the transforming ratio.
As it is connecting to the conductors which carries current,
the main care should be taken is it should be short
circuited until and unless it is connected to some external
meter, or the high voltage will get generated in it as it is
current depenedent and the ct may get damaged it is open
circuited.

In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
