SGP315 Impedance Type Distance Relay

[@Infiniteknowledgenikhilrathod]

Which author books do you referred for the switch gear and protection subject please tell me?

[@rajdeepbhowmick1228]

Sir, what is under operating of relay? As seen by the circle plot, the relay should operate as soon as the fault value enters the circle i.e. after point B. But the relay takes time upto point C to operate due to arc resistance. Is this the actual meaning of under operation of relay?

Ur videos are superb👍 sir

sir, in power system where does directional relays find application?

How power swing locus is drawn,not understood clearly sir

[@chandrashekarablshekara575]

Sir how it can be K1 / K2 is Zset, because K1 is the constant related to current and K2 is related to voltage constant

distance protection is non unit type of protection then how its protected zone can be decided @6:00

Sir how impedance relay should overreaches??

[@kuldeepbajpai1112]

Thank you sir for your valuable lectures . Sir Please provide the link for lecture series of Protection. Thank you so much Sir.

[@rameshchalakuru8529]

At point c impedence seen by relay is less than relay set , so relay operate why you called it as Mal operation occurring chance there sir ? and how can the locus of power swing can be drawn that passing through electrical centre.

[@rameshchalakuru8529]

Ok sir sure I will

[@pulkitjain1426]

Sir Due to Arc Resistance , the slope of line will also change as Total resistance increase...will it change or not?? If it changes our RX diagram will also change...

You are too good sir

Thank you Sir

[@prabhatlalkarn1880]

But the characteristic of directional relay wasn't on r-x plane then how that characteristic can be used here

[@kousikmullapudi5126]

sir is hunting and power swing both same?

[@kousikmullapudi5126]

sir can you please elaborate because in hunting synchronous motor will search for synchronisam and in power swing rotor angle is searching for new stable system.@@lecturesinelectricaleng
