Per Unit System - part 1

[@myidentity222]

well explained sir... your videos are great, and easy to understand, Thank you...

[@marien1991]

Just after 13:22 minutes, I feel, I owe you a nice comment and a like. Now that it is done, let me continue listerning to you up to the end. Thank you for your video.

[@vipinrajk1]

Correct me if wrong- 4kW @0.8pf lag is wrong statement . Correct statement - Load 4kVA@0.8laf :-). many thanks

[@jahjah7208]

thanks a lot for your vedio i learn and refresh my mind regarding electrical engineering

[@aks5436]

PLEASE EXPLAIN (55:25 ) dividing by 6 square

[@johnvann4450]

When discussing translation of per unit impedance from one base to another. Could clarify a lot by stating Actual impedance does not change regardless of base system

[@sarigubonsri2091]

Excellent of series in EE .God bless you.

[@1973jdmc]

Thank you so so much for such a brilliant lecture- truly appreciated

[@kaseidkerlstein4194]

Why is it again the Z actual is divided to 6 squared? please some could tell me because i cant seem to grasp the idea of it.

[@angelitomacasero6968]

where did you get the 6 square? i know 6 is the trans ratio.

[@pradeepyemula6015]

can you mention at what time in the video is your question about?

[@AKShah1]

Pradeep Yemula hello sir i have a doubt Can i get your email id

@@aks5436 (1/6)^2 is a^2......a=turns ratio. To move impedence from the secondary side to the primary side we multiply the impedence on the secondary side by the turns ratio squared

Hi sir, do you have a pdf copy of this lecture?

[@achaljoshi007]

Isn't it wrong to cancel kVA & KW @ 18:09 and before that, I mean how can we cancel out apparent power and real power without knowing if ckt is AC or DC? I really don't get it how kW and kVA cancellation is taking place. Sir, please explain.

[@BilalBilal-cu4zr]

Very nice idea having PU system lecteurs , I was stuck until I saw this videos

[@princemenon8864]

Sir....complex power should be in KVA right???

[@kingsleyakpeji5447]

Thank you Pradeep for your videos. Are there copyright restrictions on their re-use, say to facillitate an online course?

[@pradeepyemula6015]

Hi Kingsley. You can use the videos for online courses without any restrictions. Please donate any amount you wish to support my channel. My PayPal link is. paypal.me/pradeepyemula?locale.x=en_GB

Thank you sir your lecture is very good

[@jvenkatesh6810]

you are an amazing teacher

[@oratilemarope2480]

simply brilliant.

[@husseinshutari5209]

thank you so much, actually, your manner is very clear and useful. could you tell me how can I get all lectures about power system analysis presented by you?

[@alekhyasuhani2618]

Get seat in iith

[@sirendrakunche3492]

Sir please upload a video on equal area criterionand, swing equation

[@pradeepyemula6015]

i have already uploaded videos on the topic of equal area criteria, kindly search on my channel you will find.

[@rajarapunagarajuyadav8686]

nice video thanks sir

[@iamArrwa]

I’m a little bit confused.. are you solving for single phase or three phase ? Because as i know the apparent power of 3phase = sqrt(3)*|V|*|I|

[@pradeepyemula6015]

BTSaddicted this calculation is for 1 phase

[@pradeepyemula6015]

I have made a separate video on how to work with per unit system with 3phase. Please search later videos in this playlist.

[@iamArrwa]

Pradeep Yemula 👌🏼 thank you so much your videos are helpful

[@akileshkumar4479]

Sir at 29:29 for percentage losses you’ve to multiply by 100 because you said percentage

[@esc10]

Hello sir, In starting of lecture you define per unit as any quantity's value in out of one is per unit but in your starting examples your per unit values exceeds their maximum value i.e. 1! How's this possible?

[@mrgreatzzz7438]

Well Explained

[@subhash5122]

Please provide more videos sir🙏
