Thank you for watching the video

[@jadejaharubha7757]

Please make one more part of this zone protection. About reverse zone & zone 3 . U explained Best brother 👌👏

[@electricalexpres]

Ok I'll make, please share the video to your friends and colleagues

[@electricalexpres]

Video uploaded, please watch and Share

[@pankajrathore875]

At q location available 2 two breaker and 2 distance relay, one for p and second one for R that time how work Zone zone 2, 3 and 4

[@kaisalvi7850]

Please make a separate video Hindi about all relay in electrical power systems like as 21,95,50bf etc according to ansi standard we will grateful to you

[@electricalexpres]

Sure I'll make the video for the same

[@kaisalvi7850]

WE WILL WAIT THANKS@@electricalexpres

Zone4 reverse protection

[@electricalexpres]

I have made separate video on that, please do watch

[@chinatataraoganisetti5626]

What about reverse zone

[@electricalexpres]

Reverse zone is given for protection opposite of CT of line

[@_just_pintu]

Your explanation about why zone 1 is kept 80% is wrong.please correct it. The reason is CT,PT, CB and Relay error(5%each).

[@electricalexpres]

Right, this is also one of the reason for keeping 80% in zone1

[@vinodkumar-uw1pn]

What about zone4

[@electricalexpres]

Zone4 is given for reverse zone protection

[@electricalexpres]

Separate video on Reverse Zone protection is uploaded, please watch and Share the video. Video Link is below kzbin.info/www/bejne/nGXag3l8qbOep7M

[@adeelnawaz2838]

What about STUB,SOTF?

[@electricalexpres]

SOTF is Switch onto Fault, this protection operates, when breaker will close and the fault is persisting is the line, SOTF will give immediate trip command to breaker. STUB protection is used when single line is supplied by two circuit breaker.

What's zone 4 fault

[@electricalexpres]

Zone4 is a reverse protection, that is operates when fault happen opposite to CT of particular Line.
