Weight and mass are different. Don't mix them up. Otherwise excellent explanation. Thank you.
How did we take X/R for Source and Transformer?
Non sense
Can you provide the mentioned excel sheet? Thanks
Sir, Could u explain me how to calculate the corrected impedance voltage at rated current as shown in the above table. Thank u sir
Excellent how about thee zero sequence impedance calculation
Excellent.
Sir, Which make DC selection switch available in the market
Kindly share the PDF of all
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
sir, how did you take primary fault current as 1/4th of the secondary current. How did we get 1.09375 kA Please clarify
i was always looking forward to such a video. Great job. Thank you
Please make video also in hindi language
Sir i check 24 voltage DC our substation.i find out that positive to Earth 26voltag and earth to negitive zero potionia what is fault in system.
@@parmodyadav9966 it is negative earth fault
@@relayprotectionelectrical sir I have used vcb Earth That is right or wrong
Thank you Sir I have question: Is there equation between time multiplier and operate time? What is time dial ? Thank you
How we select the tripping time for 300 to 350ms we have any standard or it is in some practice.
Sir Hindi me hone se accha hota
Nice sir ,carry forward distance protection in next video ❤
Very good. Thanks 👍
Great job
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?
Accuracy problem will be there as meter CT is 5 A and you are going to connect meter from CT secondary of 1 A.
@@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
Great information. If two phases are reversed then it will be -E/3 right?
kon mi jmr
U ARE WRONG. if the measured voltage drop is 330v, how can be the %age voltage drop is 10%. Please answer
Thank you for your comment and watching the video so deeply. Yes you are absolutely right. It shall be 3.3 kV so that PI shall be 10%.
The results mentioned in table are according to which standard? Thanks
Power for all 3phases or single phase?
Three phase
Sir very good video, thanks
Most welcome
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....
Superb sir please tell me about as differential ct polarity
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?
(330/33000)*100=1% not 10%
Which applications used reverse polarity CT's
This video available in Hindi
Very good explanation Thanks
Very good. Thanks 🙏

Sir I have doubt in star point side current can flow?
how?
@@relayprotectionelectrical I have doubt in star point concept please tell sir
Why we need to short the HV and LV side, does it have effect on capacitance result?
Sir why p2 is connected to tra sformer side
It is normal convention. Please enroll for course on Transformer Protection on udemy www.udemy.com/course/protection-used-for-power-transformer/?couponCode=931DB6D9C361B37E48B6
Sir why we connect LV side P2 to P1? Normally current flow source(LV side of transformer)to load
Hindi langvej please
Video Hindi
Very nice sir..❤❤
Very good. Thanks 🙏🙏🙏🙏
Why required double DC supply or separate DC for CRP
Because in CB there exist two trip coil... And in CRP there exist two main relay for voltage level 66 KV and above i.e. Main-1 distance relay and Main-2 distance relay .. therefore separate DC supply are given for main-1 and Tc-1 and main-2 and Tc-2 because failure of one DC will not impact relay and cb operation during fault condition.
