Very good lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏

Φ2 in both side will not act in the same direction. Φ2 in left and right will be directed in opposite direction.

Sir is CT is also part protection device like fuse and C.B??. Because the pick-up current of relay is way more than the rated current of C.T, so the fault current may damage the C.T even before relay pushes the C.B to open.

Sir link for doc file

[@sachinkale4093]

If the secondary current under fault condition in 100/5 CT is 100 and current setting of relay is 125 percent. then find out psm

ok

@@lecturesinelectricaleng sir here can i take 100 A as a fault current

[@sachinkale4093]

sir how to find fault current of relay...plzz tell me sir...i am become confused...and final answer kya ayega

[@kousikmullapudi5126]

Bro u must not take fault current as 100 because it is Ct ratio. For suppose if a transmission line is carrying a current of 500A and fault occurs if 600A is flowing the ratio becomes 30(fault current in relay). I hope you understand

Sir can we get slides of this video... For quick revision in future
