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.

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened.
