If there is any word that is more than Thanks i would like to say it ,but as far i only know thanks , this is very helpful to us no other channel explains alternator protection concepts this clearly keep continuing sir and make videos on HT motor, ACB breaker ,VCB breaker ,SF6 breaker protection scheme and 132kv switch yard protection, power and Distribution Transformers protection scheme. This is very useful channel for Electrical Engineers with lots of valuable industrial knowledge we can't find any where 🙏🙏🙏🙏🙏👌👌👌👌🙏🙏🙏👌👌 Keep continuing 👌👌👌👌

Generator is grounded through high impedance and the fault current is restricted to just 10A to save the stator core. Differential doesn't act for such small currents. These faults are taken care by stator earth fault relay.

Absolutely correct.

Wonderful sir.. Nicely and thoroughly explained. I am working in 500MW thermal plant as a control room incharge. Today @08:04Hrs our Generator tripped on 87G protection. (Differential) After primary findings it was observed a sudden dip of 4KA in R phase current (Generator was delivering 12KA at that time) That dip of 4KA was only for 145milli Seconds. I want to ask you, can't we give time delay in settings so that it should not operate if fault resets in 100mS

Sr T/F charging k uppar v ek video dijiye na Plz Aagar hum T/F charging krte hai to kya wo v inrush current leta hai?

Do you mean v/f?

@parvezalam3843 Жыл бұрын

Nai sir.. Mera mtlb ye hai k jb hum T/F pr load connect krte hai to kya wo v motar ki tarreh hi inrush current pik krta hai Ya ki wo apne rating pr hi work krta hai?

Respected Sir, My relay Differential relay DTH31 (Electromagnetic relay) Relay name plate relay operating current 1A But i take Bias testing DC current inject 2.5 A and varying AC current. Why not relay burn out for 2.5 A current. Please explain briefly. Thank you

Where connect two ct for differential relay if the 4wire out from the generator

@ElectricalTalks Жыл бұрын

Good observation 😊 Actually in practice, you will find total 6/9 terminals out of generator. Neutral point is made outside the generator casing. In inter turn protection, 9 terminals concept will be discussed.

@@ElectricalTalks thats mean in generator we connect ct to inner protaction and out of protaction where connection
