This music is fire🔥🔥

[@siddalinga786]

Y we cannot connect directly all the realys to c.b. by using contactor

[@SubstationSystem]

Sidda Linga required high speed operation for tripping the CB and master relays are high speed tripping relay

[@siddalinga786]

Tq sir but it's only mechanical relay

[@hiddenarray2315]

protection relays r expensive, so master relay will proxy in behalf of the other relays to trip the cb
