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.

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

[rameshtripathy]

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 .

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?

[mageshsvm]

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

[enriqueh]

Thank... Thank very much for doing this video and addition for the first part.. :)👍👍👏

[mdnoor]

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

[Falcon_Kashmir]

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

[सिर्फसत्य]

Please make a video on Directional earth fault. In hindi

[balakumarlingan.powerproje]

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

[senthilazhagan]

Thank you so much sir, , these time much needed for this video, , , thank you so much

[hariharan]

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

[PLAYWITHPHYSICS-sl]

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

[munisamypanneerselvam]

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

[diyamallick]

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

[rameshraja-dyql]

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

[arielquesada]

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

[miraclelearning]

Application of directional relay in loop feeders ?

[avinashpatel]

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

[manishkumarrawat]

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

[ashishthorat]

Good explanation....helped me a lot.
