Sir no problem in video. I want to know smthg more..... How is the connection of relay when we use REF for a line? and What is REF non directional stage 1 start or stage 2 start and stage 3 start
Today I read this scheme from the book of JB Gupta, I hardly understood the working principle, but after watching this video, it's crystal clear. Thank you
Ye video dekhkar aaj muze lag raha hai interview me agar muze pucha jaye aur me definitely iska ans kar pauga and mera impression bhi positive rahega..
Great upload. You explained really well. Next topic: How to choose the CT ratio and C value (C100, C200 etc) so the CT doesn’t saturate during a fault?
Very clera and sound as well as informative, Thanks . Please make a detailed video on transform oil testing and action incase of oil contain danger gas, furan test analysis and action.
Abhishekji, beautifully explained. Can you just add, what will be the scenario if the transformer winding is delta connected?How the CTs will be connected?
Sir apane bahot achha bataya hai.....I m also electrical engineer....but college me jitana nahi samjha usase kahi jyada ap ne achha smjhaya hai....thank you very much sir🙏🙏🙏 for your efforts....
Mere solar plant me 5mva TRAFO ka REF tripping relay operate hota hai jab outside area (substation) me earth fault hota hai.. restricted area k bahar k faul pe operate nahi hona chahiye na... Stabilizing resister work nahi kar raha kya? Please suggest more....
Sir you have explained beautifully. Thanks for sparing time & making such informative video . I have few queries, request to address them . 1. Why this REF protection only use in transformer having capacity equivalent or more than 2.5 MVA? 2. REF protection Relay will be installed in primary side of transformer or secondary side ? Once again thank you very much for this video . 🙏🙏
Sir...you are doing very great job for us in simple language to make us understand.. I hav bit confusion if fault occur outside then current will also come through stabling resistor in relay or will follow other path to NCT...kindly clear my doubt..🙏
