Hi friends this channel is all about sharing of my experience in the field of electrical engineering and protection system. Different types of relays used in sub station for different protection purpose. Each of relay has specific part on protection. I am trying to share my knowledge and this is why I choose this platforms. Please go through the videos uploaded in this channel. Your valuable comments are welcome. Please follow on Quora in the following link relayprotectionelectrical.quora.com/?ch=10&oid=2359855&share=396067ef&srid=ya35n&target_type=tribe
please make video on various relays 50, 50N, 51, 51N and their settings. How are they selected for various applications. Is there is standard list? please clarify
Great info. I have a question. If external ct ratio is 180/1 and external pt ratio is 22000/110, meter ct ratio is -/5 and pt ratio is -/110. Is it possible to have such connection? If yes, then what will be the multiplying factor in that case and if no, please share the reason why?
@@relayprotectionelectrical thanks for replying 🙏 How much difference in reading should we expect? At present we are using such set up in one of our feeders and taking readings on that basis. As you’re saying there will be accuracy issues, is there a way to evaluate how much difference in readings are we talking about? In the above case we are using MF as 36000
R & Y phase will carry 54 A, how? R is shorted to earth. Will it be R & Y or Y & B? In your previous differential stability test video I(LV) = 93.31A. Please clarify....
thank u sharing ..plz mention transformer vector group and rating , voltage ratio. suppose if trafo is DYn1 vector group then connection type 1&2 are in relay settings?
It is normal convention. Please enroll for course on Transformer Protection on udemy www.udemy.com/course/protection-used-for-power-transformer/?couponCode=931DB6D9C361B37E48B6
