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

Answer Posted / dixit

CT means current x'mer. in actual field high amount of
current in turms of KA so measuring this current is
difficult & also relay current is also less.so, for
reducing current (pri.-high current & sec.-1A OR 5A)CT is
used.
care must be taken that always CT sec. are shorted because,
at sec. less current and high voltage is present. if it is
open than this high voltage affected field operator.
