Professor you are the best as usual The most professional one on RUclips knows how to make the lecture very easy to understand and anyone can follow you You have skills to be a teacher better than professors/PHD teaching in university I greatly appreciate your time and your lecture I enjoyed so much
Sir You are an excellent teacher, very methodical, paced and articulate. I would have benefited greatly should you have been my teacher in college, thank you so much for this video and I look forward to future ones related to short circuit calculation analysis.
Good one. I also find it to be more convenient to work all on 1 MVA basis by dividing all PU values by respective equipment MVA rating. Finally just add up all PU values (Xsum) and divide 1000kVa/ root3 × 22kV× Xsum. (I.e., Xsum= 0.15/25+0.09/30+0.092/100+ 0.02/5)
Hey Abhishek I hope your day is going well. I'm currently reviewing my Electrical Power Engineering notes and problems. Your video provides an excellent example that covers a variety of topics a practicing Engineer will encounter. This is the first time I've seem your RUclips channel. I will definitely be viewing the rest of your videos. Keep up the good work.
Thanks for sharing the video Abhishek. I'm currently reviewing my Electrical Power distribution notes and this video has been very helpful. Hope you share more videos like this in the future. Cheers.
thank you sir for your video. Can I request example regarding of having a given details in the load. like you've said if there is a synchronous motor. Thanks!
Excellent video as usual Professor Please if in the same problem the load is dynamic how we obtain the regally voltage and the internal voltage of the generator?
for the transformer xpu, why solve twice, is it important to solve for both windings or just one winding is acceptable to get the value, I read some books that the kv new is the voltage in the second winding and the kv old is the voltage in the primary winding. it is confusing sir. thank you
How to find the old perunit reactances of equipment, and in case load is dynamic ex.motor, how to calculate the prefault. Voltage, generator voltage and fault current, explain with same diagram it will be very useful. And in case line to ground or L L G fault occurred how to calculate
What happen if the load has impedance value. Do we need to consider it for fault current calculation. Or we need to ignore it. Please help me clarify this.
Hi, I used 25MVA as the power base. Generator is 0.15pu. TX-1 is 0.075pu, T-Line is 0.092 pu and TX-2 is 0.1 pu. Total reactance is j0.417 pu. Base current is 0.6561kA. I am unable to get the same magnitudes as your answers. Please explain where I went wrong.
Well explained sir thanks for that ...can u do me a favour plse tell me plse how to record video using mobile means how to hold mobile or is there any holder available online if any please share link of. I will nmbe thankful to u . Thanks in advance.
You can pick ANY number, it doesn't matter as long as it is consistently applied. Typically 100 MVA is used. But it also good convention to set Snom equal to the highest rated power of any equipment in the network.
In calculation of fault apprent power you say the voltage is equal to voltage at busbar 2 just before the fault at the time of fault the voltage is 22 kv but you write there is 1 how please solve my this problem
You choose the highest MVA in the single line diagram because it is easier to work with. You can choose any logical value and follow the same procedure, the final short circuit should be the same.
Great video! thank you for sharing and explaining EXTREMELY clearly! I really appreciate that you take your time with each step! Thanks again!

Thank you Sir for excellent lecture. never seen like this clear explanation !!
Thank youuuu, my tutor didnt even understand what he was teaching but you have made it super clear!!
Wonderful explanation on Power Systems Fault Analysis. All my Electrical Engineering colleagues should follow this.

Thank you for a good, clear, understandable lecture. I like the practical example all the way through from start to finish.
Thanks a lot sir. Exams se pehle bacha liya aapke video ne. keep up the good work. Easy to understand and learnt ASAP.
I understand everything you're a great Instructor.
Base value and base voltage selection concept... Super...
🙏👌
Great... The art of teaching is excellent
thanks sir for making my concept clear i was your student only sir from srm university
Good explanation, it was a good idea the use of paralel lines to determine the per unit values, i had never seen it befor, congratulations
great video. very clear and well explained. thanks
why do we ignore the voltage drop across the transmission line? And how do we get the given per units on the SLD?
Thank you man finally the video I was looking for
Thanks for sharing the video Abhishek. I'm currently reviewing my Electrical Power distribution notes and this video has been very helpful. Hope you share more videos like this in the future. Cheers.

Well job, superb lecture u wash out my doubts
Thanks for the explanation
To get fault current I would have divided generator voltage by all line impedances... is that wrong?
Thanks and love from Bangladesh
thank you sir for your video. Can I request example regarding of having a given details in the load. like you've said if there is a synchronous motor. Thanks!
thank for tutorials
Hi Abhishek , I like your lecture. Thanks
thank u so much sir I cleared all my doubts
Outstanding explanation tq very much sir👌👌👌
extremely wonderful explanation
tnx sir you are a genious......I love this chapter after wathing this video.
Great representation Sir,congrats!
Excellent video as usual
Professor Please if in the same problem the load is dynamic how we obtain the regally voltage and the internal voltage of the generator?
Nice lecture.....Pls share information on instrument transformer saturation...
well explained, waiting to see more such videos from you.
What is, common base 100 mva from where he get that
since the per phase network diagram is considered why we take pu line voltage instead of pu phase voltage?
VERY GOOD LECTURE... THANK YOU...
Great video
Can you explain why symmetrical fault
L-L-L-G and L-L-L is same?
Very good explanation..
Thanks Sir 🙏🙏🙏🙏🙏🙏🙏
Thank you so much for this ❤️
for the transformer xpu, why solve twice, is it important to solve for both windings or just one winding is acceptable to get the value, I read some books that the kv new is the voltage in the second winding and the kv old is the voltage in the primary winding. it is confusing sir. thank you
Thank you Sir for excellent lecture.
superb video sir...
How to find the old perunit reactances of equipment, and in case load is dynamic ex.motor, how to calculate the prefault. Voltage, generator voltage and fault current, explain with same diagram it will be very useful. And in case line to ground or L L G fault occurred how to calculate
What happen if the load has impedance value. Do we need to consider it for fault current calculation. Or we need to ignore it. Please help me clarify this.
sir,
from where you get the transmission line 100 MVA , 0.092 pu while calculating the Short Circuit Current
Thanks
Great class sir.. u helped me.....
Hi, I used 25MVA as the power base. Generator is 0.15pu. TX-1 is 0.075pu, T-Line is 0.092 pu and TX-2 is 0.1 pu. Total reactance is j0.417 pu. Base current is 0.6561kA. I am unable to get the same magnitudes as your answers. Please explain where I went wrong.
Did you work out this problem by MVA method or ohmic impedance method?? MVA method with ms Excel gives same result.
great video.
that actual fault current is phase current or line current?
thank you sir
extrmly nice lecture
Thanks...
Well explained sir thanks for that ...can u do me a favour plse tell me plse how to record video using mobile means how to hold mobile or is there any holder available online if any please share link of. I will nmbe thankful to u .
Thanks in advance.
Very nice👍
great job sir
well explained
sir please upload power system all lectures related to gate exam it will help us .. thank you so much..
Can you tell where can i find example where load is dynamic.
Thank you for sharing
thanks for this video
How do you just select command base MVA? Can you select 50mva? Why 100MVA
Thank you
which base power will be selected as base power out of T/Line ,T1 & T2 KVA ratings i.e 100 MVA,25MVA & 5MVA ? How did we select 100 MVA as base power
You can pick ANY number, it doesn't matter as long as it is consistently applied. Typically 100 MVA is used. But it also good convention to set Snom equal to the highest rated power of any equipment in the network.
yes, you can pick any number. But usually, we take the greatest MVA value in the given system.
sir all the video for learning concept sir please upload field theory video which is hard to understand
thanks bro
Super
All douths clear
Hello teacher, I have a question about the power systems analysis course, can you help me?
According to transform ratio 132÷11=12 ,how 132 has come in transmission line???
After multiplication of primary side voltage 11*12= 132

Sir i have doubt what will we do if the hv, lv sidea of transformer is been given as star and delta.
Please give me the ans as soon as possible

Sir we are using only one transformer 11kv to 66 kv so how to calculate
Tq u sir
Sir, can you recommend me a book for that lesson? Thank you.
Thank u...sir
In calculation of fault apprent power you say the voltage is equal to voltage at busbar 2 just before the fault at the time of fault the voltage is 22 kv but you write there is 1 how please solve my this problem
Please mention WHY choose 100mva as common base MVA.
You choose the highest MVA in the single line diagram because it is easier to work with. You can choose any logical value and follow the same procedure, the final short circuit should be the same.
How did you get 100 MVA old as base power for transmission line
This is my assumption
