Directional Over current relay|Protection of parallel lines|Directional over current protection

Directional over current relay or directional over current protection is very much essential for systems having parallel path, sources at both end and ring system. Non directional protection causes loss of the entire source in the event of a fault. Directional protection can prevent that and isolate the exact faulty circuit.

Excellent explanation

[@rajinderjaat7480]

Very helpful 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 .

Does it operates on reverse current ?????

[@legendarygamerprince5317]

Nice video sir 🙏from SAP

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

[@diyamallick1838]

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

[@617ashishthorat4]

Good explanation....helped me a lot.

Hi, I like your video. Thanks

[@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

[@call0ahmed1]

Good

[@badshahibrahim8475]

Thank for it 👍🏻👍🏻👍🏻👍🏻

[@rameshraja-dy1ql]

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

[@balakumarlingan.powerproje5493]

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

[@arielquesada3538]

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

[@natureexplorer_07]

I 100%understood

[@arunkumar-sq8sj]

Think you very much 🙏🙏🙏

[@BabarAli-zu9pu]

Thank you so much sir

Application of directional relay in loop feeders ?

[@Cragsman_Qureshi]

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

[@jihad_96]

Thank you

[@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

[@user-lg5lg3tt9m]

Please make a video on Directional earth fault. In hindi

[@hariharan4674]

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

[@electricaltechnologyandind5335]

Use fuse.

[@user-wm5ti1od6r]

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

[@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]

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... ☺
