Thank you sir. Very nice explanation and Very useful for Electrical department people.

[@ronaldosilva330]

Nice explanation!

[@manishkumarrawat5341]

Aap bahut achha explain karte hai sir industrial point of view theory and practical ka achha combination batate hai

[@prabhakarangovindaraj9238]

Daily i waiting for your new video finally i got new video with very good teaching thank you sir👏👏👏👏👏👏👏👍👍👍👍👍👍👍

[@rameshtripathy5978]

Very good description with clear examples ! I am sure it is helpful for our young commissioning engineers & technicians ! Thank you so much Sir for your efforts to educate the young engineers .

[@aloksrivastava4260]

Does it operates on reverse current ?????

[@vipulmishra7779]

Best explanation ever. Thanks a lot.

[@AshokKumar-fj3ry]

Very informative

[@ehtishamasghar9204]

Hi! I have a question in the first case of fault with directional relay, why CB with 51 relay on the lower line will not trip?

[@mojixijie1068]

Because the breaker at downstream I guess

[@mageshsvm3235]

This valuable videos for understanding O/C ,Thank you sir

[@diyamallick1838]

very well explained thank you so much sir for making it too easier😄😄

[@somanathanraju847]

Excellent explanation

Think you very much 🙏🙏🙏

[@himanshu2232]

Thank u sir mere request per apne ek achha vedio banaya.

[@electricaltechnologyandind5335]

I will make video on its working principle and setting calculation shortly. Stay tuned

[@BabarAli-zu9pu]

Thank you so much sir

[@navratankedia]

Excellent ..... Thanks for such a beautiful videos

[@PoonamYadav-ny8rx]

Thank you sir

[@call0ahmed1]

Good

[@Falcon_Kashmir]

But fault current will still pass through the healthy section. How timing is configured

[@balakumarlingan.powerproje5493]

very nice work you are doing..Will you share this ppt?

[@mdnoor2929]

Thanks for your informative videos. How can I get operational principle of 21,87T, 51....all these electronic device activity..

[@PLAYWITHPHYSICS-s9l]

In ac circuit current direction reverses every 0.02 sec . What is the direction exactly relay sees

[@electricaltechnologyandind5335]

Active component of the the current, I cos theta

[@miraclelearning430]

Application of directional relay in loop feeders ?

[@hariharan4674]

Sir,
for 33kv RMU system-Incomer side, Which type of protection to be use Direction or Non Direction?

[@electricaltechnologyandind5335]

Use fuse.

[@rameshraja-dy1ql]

Hello sir.... Very useful video... 👍👍👍Please explain about where we need to use high impedance relay and low impedance relay???and why????

[@सिर्फसत्य]

Please make a video on Directional earth fault. In hindi

[@arielquesada3538]

Sir how do you calculate the CT ratio for both directional and differential relay?

[@avineshbarangule8537]

Why there is necessary of bus bar diff protection as 51 o/c protection is there on the lines as bus bar diff will also cutout source.

[@narenchauhan3241]

To maintain reliability , selectivity..

[@electricaltechnologyandind5335]

Bus bar differential relay will operate faster than oc relay, also if bb diff operates you can be endured that the fault has occurred inside the bus bar zone.... Which basically selectively as @Naren Chauhan mentioned

[@narenchauhan3241]

@@electricaltechnologyandind5335 Thank You, For clearing doubt more at depth..You are the best channel..

concept is good but i request you please dont speak gramatically incorrect english, you teach in hindi, thats pretty good

[@electricaltechnologyandind5335]

Hindi is not my mother tongue, and do not tech English grammar. So i hope you will be kind enough to ignore my grammatical mistakes and focus on the technical theory... ☺
