Thank you very much. You explained the topic very nicely.
Well explained
your videos are helping me a lot, thank you, keep posting
Your speech and explanation is very nice
Thanks a lot , please we need Busbar design and protection , Distance protection and Lightning protection for Substations.
Very good video
Great Sir upload more vedios
Great vedio!
Well Explained Thank You Mister Unknown. Do Explain on others Topics
very good explanation
Superb
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.
Make some videos on TX line protection, relay testing, distance relay, BCU etc
Please explain about Spill current and spill voltage in unstable condition.
Thanks for the explanation
Plz can you give me some information about the protection under voltage F 27 how it work ?
Nice explanation. How current is flowing through relay during in zone fault since there is a stabilizing resistor connected in that path?
How the positions (primary) of the CTs to be arranged (P1 & P2) for both the line and neutral CTs?
make a video working principle of capacitor bank for 132 kv and reactor 400 kv , shunt and series
Nice !
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 .
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?
Yes . Please explain with numerical relay and mainly per unit system.
Hi sir.. Please upload a video on rotor earth fault relay 1st & 2 nd stage of brushless execitor AC Generator..
Please do the vedio on rotor earth fault with BRUSHLESS ac Exciter to a alternator ..
Sir plzz upload more videos
SIR WHAT IF THE NEUTRAL CT GOT SATURATED ....WILL THE CIRCUIT FEED ANY CURRENT TO THE 64R RELAY...
thank you .. how to implement delta side ref protection?
By providing earthing transformer
Have a zigzag connected transformer to derive a neutral..
How to connect s1 & s2 of ph ct & nct
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.
what is ct saturation ?
No more magnetisation.
