What is C.T, why it is used and what care should be taken
for that while connecting?
Answer Posted / vishvesh
normally in high voltage line is it not possible to measure
current directly by any instrument for measuring of
protection purpose. CT (current transformer) as the name
suggest step down the value of current to very nominal
stage so that normal instrument can get reading from it.
and with progressive ratio calibration. we can get actual
value of current flowing through the line. also the relays
for the protection are connected with secondary of CT.

1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
