Impedance Diagram | Per Unit System | Power System Analysis

[@bookieguy6233]

Hello, In fact, all you KZbin instructors are marginally underestimated. you guys are provide significant knowledge to the public with the BIG STUDENT LOAN!!! THANKS!!

[@shahzadhashmi1454]

Nice bold hand writing ... well explained

[@roy_shuvo]

T1(z pu new)= .12*(200/90)*(25/25)^2 T2(z pu new)= .12*(200/90)*(25/25)^2

[@amitjoshi5700]

in 26:05 for Power line per unit calculation Pactual is in MW & P base in MVA

[@arghadeepmandal4399]

For calculation of Z base you took 220kV as base voltage... but the base voltage is 25kV in question

[@anymotion22]

Draw an impedance diagram for the electric power system shown in Figure 3.32 showing all impedances in per unit on a 100-MVA base. Choose 20-kV as the voltage base for generator. The three-phase power and line-line ratings are given below. G_1: 90 MVA 20 kV X = 9% T_1: 80 MVA 20/200 kV X = 16% T_2: 80 MVA 200/20 kV X = 20% G_2: 90 MVA 18 kV X = 9% Line: 200 kV X = 120 Ohm Load: 200 kV S = 48 MW + j64 Mvar Please solve this

I forget all that impedance diagram but in easy way you remember all this things.thanks Vishal Sir

[@1973jdmc]

You sir are a life safer- THANK YOU SO SO MUCH- you are now officially a Super Hero- MR FANTASTIC

[@SmilePlease-08]

Please continue your lecture sir, thank you

[@ritukaraj4610]

Sir in jb Gupta book example 11.for calculation of base kv in gen ckt.. It is multiplied by 1/transformation ratio. And in motor it is multiplied by transformation ratio only.. Plz sir explain these doubt.

[@sukdebbarai1015]

Thank u so much sir

[@sanchitathombre3162]

Fantastic 😍

[@samikpal5585]

for the last example I'm getting, Load Resistance= 0.6 p.u. & Load Inductance= 0.8 p.u. Am I correct????

[@thippeswamy3962]

sir i need continuation of this class

[@shriramprajapat4226]

sir plz increase length of your video. it should be around more than 1 hour's.

[@nabarunchakraborty5264]

1 mistake is there sir ! U should take X=0.12 In step 2 .

[@chandan2462]

And also T1 ka old Sbase 90 hoga

[@varunlover]

More class on this please

[@sanchitathombre3162]

Kya ap abhi nhi pdhate h gate academy me?

[@shivankmisra6523]

8:12 200/90

[@947tahsina9]

i had the same qstn..if is it 200/90 or 200/100 :/

[@shreemannarayan5755]

@@947tahsina9 one more mistake in question transformer reactance 12% given not 9%

[@VinayakHase]

Reactance is change for Transformer i.e 12% you put it 9% please Explain?

[@uniquename2823]

he did it wrong i guess

[@parasgautam9987]

SIR REACTANCE TRANSFORMER 1 KE LIYE 0.12 KU NHI LIYA

[@Ashutoshkumar-pj8vz]

Sir Plz send the lectures as soon as possible

[@Hero123-w9v]

Plz sir upload as soon as posible

[@VivekKumar-cb6kl]

sir plz upload power system stability lectures

[@vijaykumardewat8602]

Sir symmetrical fault par video bnao

[@mansteel2898]

U are doing wrong in 8:59 the transformer impedance is 12percent not 0.09

[@jitendrasharma6406]

Sir more video sir on fault and stability

[@shilpasweety641]

Sir write thickly we can't see at the end part of the board

[@mayushapatel3050]

Zpunew ki formula kaise aayi?

[@sidhantsingh9577]

watch previous lecture

[@sanketdkadam]

Thank u sir

[@jdrm5500]

The idea of 10 MVA generator injecting 108.16 MW in the network is keeping me awake... Could someone help?

[@jagadeeshchalla5578]

Please complete fast sir

[@sumittiwari327]

Sir blue marker se clarity nahi aati hai koi and colour use kijiye

[@shoikothassan4422]

Sir, maf karna mujhe..apne calculation pe galti keya hay..

[@nehaagrawal3864]

Can some one plz explain me why x for t1 is 12%why it is taken as 0.09

[@afsiddique]

IT IS TAKEN AS 12% ..Sir made a mistake and then corrected it @13:13

[@sumittiwari327]

Sharab Ke video Mein clarity nahi aati hai please camera paas mein Karke Choda record kijiye and sir DC Motor DC generator and transformer etc ke video bana Kar Dala sir please did se do ghante ke

[@avinash2178]

not understand last example PLZZ provide solve another example

[@vengaladdu5741]

Pllls sir send u r videos very soon possible

[@yashwabhitkar6070]

Are yaar camera thik se pakdona itna bekar shoot kyu kr rhe ho dekhneme kitna dikkat hota hai hame

[@riteshsrivastava8711]

thanks sir
