REF Protection and it's satbility

[@giftsiadimbz9824]

Well explained

[@suprodipdas119]

your videos are helping me a lot, thank you, keep posting

[@ashishbanerjee8436]

Thank you very much. You explained the topic very nicely.

[@SKS9091]

Your speech and explanation is very nice

[@prabhatprajapati5799]

Very good video

[@manishprasad31]

Great Sir upload more vedios

[@SathishKumar-un5rz]

very good explanation

[@jigneshdhokia6195]

Superb

[@anwarullakhayoom7863]

Thanks a lot , please we need Busbar design and protection , Distance protection and Lightning protection for Substations.

[@sathyanarayananramachandra8097]

Well Explained Thank You Mister Unknown. Do Explain on others Topics

[@nitinkamath.A]

Great vedio!

[@shashikant79]

Your all videos are very good. U explain very well.
But why did u stop uploading. Keep uploading n help to enhance knowledge of others too.

[@shashikant79]

Make some videos on TX line protection, relay testing, distance relay, BCU etc

[@raheestk2779]

Nice explanation. How current is flowing through relay during in zone fault since there is a stabilizing resistor connected in that path?

[@tangiralayadithya6350]

Please explain about Spill current and spill voltage in unstable condition.

[@user-ng5rc4cj9j]

Thanks for the explanation
Plz can you give me some information about the protection under voltage F 27 how it work ?

[@mohammadpathan4668]

Nice !

[@AmitkumarEVB]

make a video working principle of capacitor bank for 132 kv and reactor 400 kv , shunt and series

[@gurpreetsinghsohal1958]

thank you so much. What about the low impedance ref prot? using the numerical relays? are the CT secondary currents converted in pu and the rest concept is the same?

[@sharathmsg4436]

Yes . Please explain with numerical relay and mainly per unit system.

[@charinath5445]

How the positions (primary) of the CTs to be arranged (P1 & P2) for both the line and neutral CTs?

[@anutripathi2314]

Sir plzz upload more videos

[@sharathmsg4436]

Sir , u have explained neatly high imp ref . But after that low imped ref with numerical relay not explained sir .please EXPLAIN separately .
we have 15mva tf , NCT , ALSTOM RELAY and there is no such circuits present near my relay wat u have explained in your vedio. We just fed NCT terminals to relay terminals separately and power side CT are fed separately to numerical relay . . How I can incorporate ur ckt with this numerical relay .

[@MRASIFRAZA1]

Hi sir.. Please upload a video on rotor earth fault relay 1st & 2 nd stage of brushless execitor AC Generator..

[@sharathmsg4436]

Please do the vedio on rotor earth fault with BRUSHLESS ac Exciter to a alternator ..

[@juleshdas3863]

SIR WHAT IF THE NEUTRAL CT GOT SATURATED ....WILL THE CIRCUIT FEED ANY CURRENT TO THE 64R RELAY...

[@Arijit_VU3ICT]

thank you .. how to implement delta side ref protection?

[@manojkumar-jd6ct]

By providing earthing transformer

[@rajeshtk1246]

Have a zigzag connected transformer to derive a neutral..

[@Arijit_VU3ICT]

what is ct saturation ?

[@anwarullakhayoom7863]

No more magnetisation.

[@vaibhavvasekar2114]

How to connect s1 & s2 of ph ct & nct

[@rajeshtk1246]

For REF, connect them in such a way that they cancel out each other, so that in normal condition, no current flows through the REF relay coil.
