what composit error,ratio error,phase error in CT and PT??
Answer Posted / gunasekaran
composite error is combine of the ratio and phase angle
error ratio error deviation from the rated sec current phase
angle error is phase displaceme from primary current it is
+-60sec
suppose 5p20 ct composite error is +-5%
ratio error is +-5% phase angle error +- 60sec

Can u explain : what is supply for train (whether a,c or d.c ).I know that supply is 25000v a.c .But there is rumour that supply is D.C. And also explain how lights and fans inside the trains are working ,and what type of motors are used in trains whether D.C motors or induction motors .If d.c motor, how it gets supply.If traction motors are used then what are traction motors and its functions and how it differs from other motors and also explain about locomotive . y d.c series motor in train.train wheels r driven by D.C shunt motor ,at what voltage,and at what speed. please reply..............
