Professor you are the best as usual The most professional one on UA-cam 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.
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 UA-cam channel. I will definitely be viewing the rest of your videos. Keep up the good work.
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)
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?
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.
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.
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.
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
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 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.
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!

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

Thanks a lot sir. Exams se pehle bacha liya aapke video ne. keep up the good work. Easy to understand and learnt ASAP.
Thank you for a good, clear, understandable lecture. I like the practical example all the way through from start to finish.
Base value and base voltage selection concept... Super...
🙏👌
I understand everything you're a great Instructor.
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 man finally the video I was looking for
thanks sir for making my concept clear i was your student only sir from srm university
To get fault current I would have divided generator voltage by all line impedances... is that wrong?
why do we ignore the voltage drop across the transmission line? And how do we get the given per units on the SLD?
Great... The art of teaching is excellent
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
Can you explain why symmetrical fault
L-L-L-G and L-L-L is same?
that actual fault current is phase current or line current?
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!
Thanks for the explanation
Well job, superb lecture u wash out my doubts
Thanks and love from Bangladesh
Hi Abhishek , I like your lecture. Thanks
Did you work out this problem by MVA method or ohmic impedance method?? MVA method with ms Excel gives same result.
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?
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.
since the per phase network diagram is considered why we take pu line voltage instead of pu phase voltage?
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.
great video. very clear and well explained. thanks
thank u so much sir I cleared all my doubts
extremely wonderful explanation
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.
Great representation Sir,congrats!
Great video
tnx sir you are a genious......I love this chapter after wathing this video.
thank for tutorials
Outstanding explanation tq very much sir👌👌👌
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
Nice lecture.....Pls share information on instrument transformer saturation...
Can you tell where can i find example where load is dynamic.
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
Very good explanation..
sir,
from where you get the transmission line 100 MVA , 0.092 pu while calculating the Short Circuit Current
well explained, waiting to see more such videos from you.
What is, common base 100 mva from where he get that
VERY GOOD LECTURE... THANK YOU...
superb video sir...
How do you just select command base MVA? Can you select 50mva? Why 100MVA
sir please upload power system all lectures related to gate exam it will help us .. thank you so much..
Thanks Sir 🙏🙏🙏🙏🙏🙏🙏
Hello teacher, I have a question about the power systems analysis course, can you help me?
Sir, can you recommend me a book for that lesson? Thank you.
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
Thanks
Thank you so much for this ❤️
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
extrmly nice lecture
Great class sir.. u helped me.....
great video.
Thank you Sir for excellent lecture.
According to transform ratio 132÷11=12 ,how 132 has come in transmission line???
After multiplication of primary side voltage 11*12= 132

great job sir
Thanks...
sir all the video for learning concept sir please upload field theory video which is hard to understand
Very nice👍
well explained
Sir we are using only one transformer 11kv to 66 kv so how to calculate
thank you sir
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.
Which book question is this?
Super

Thank you for sharing
thanks for this video
Its urgent sir plz make a video on LG fault ,L-L fault and LLG faults. Please it humble request.
Thank you
Sir how to calculate prefault voltage sir plz tell me
All douths clear
How did you get 100 MVA old as base power for transmission line
This is my assumption
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.
Tq u sir
thanks bro
