SGP313 Universal Relay Torque Equation 

thank you sir for these videos , these are full of conceptual knowledge.

Thank you sir

Very good 😊🙏🙏🙏🙏🙏🙏😀

Sir when earth fault relays are there on neutral connections then why are we requiring these earth fault relays again ?

awesome sir i have a question to you sir ,are you from Andra pradesh

Thank u सर

And im from north east state tripura but in Himachal Pradesh

Is this torque equation also applicable for electromagnetic attraction type of relay as there is only one flux??

sir, can you give me a derivation of Universal torque equation?
