@@GeniqueEducationTeam Thank you very much sirji!

[@deeznuts-pf2lv]

Soujanya Mohanty it is pretty straightforward. Short circuit MVA (per phase) is Ef*If. Means total 3 phase Short ckt MVA would be root(3)Ef*If Here Ef=VL (line voltage) and If=VL/Z So SCMVA= root(3)*VL^2/Z But Z=Zpu*Zbase And Zbase=VL/IL => Z=Zpu*VL/IL Putting in SCMVA: root(3)*VL^2/(Zpu*VL/IL) But IL=MVA/(root(3)*VL) Putting in SCMVA eqn: SCMVA=MVA/Zpu =50/(0.1+0.1+0.1+0.1) =125MVA So for symmetric fault you don't even need to find individual MVAs. Just take base MVA and divide it by the sum of all Zpu values.

Khatarnak method.. Itna assan.. Thank you sir.❤️

[@Sonukr_52]

3rd method is much easier than other... Sir, your hard work will definitely give us a bright future.... Thanks a lot sir ji🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻

[@deeznuts-pf2lv]

3rd method derivation: Total 3 phase Short circuit MVA = Root(3)*single phase short ckt MVA= = root(3)*Ef*If = root(3)*Ef^2/Z (where Ef is base voltage and Z is total impedance actual value) Now Z=Zpu*Zbase But Zbase= VL/IL (line voltage/line current) = Root(3)*(VL)^2/MVA (where MVA is the 3 phase base MVA) Hence, Short ckt MVA = Root(3)*Ef^2*MVA/(Zpu*root(3)*VL^2) = MVA/Zpu {since Ef=VL} = MVA/(Zpu1+Zpu2+...) In the example, base MVA=50, Zpu1=Zpu2=...=0.1 Hence, short ckt MVA= 50/(0.1+0.1+0.1+0.1) = 125MVA

[@jigneshkoladiya831]

3rd method is great one and its totally new. No one had discussed this method earlier. It will be helpful to so many students. Your hardwork is always appreciable.

एक मित्र ने इस मेथड को बताया था मुझे , लेकिन ये कैपेसिटर वाला कांसेप्ट सुंदर था !! पूरे सिस्टम के कॉमन बेस mva को लेकर उसे अगर equivalent series pu reactance से divide करेंगे तो भी answer 125 mva ही आएगा ! Base MVA divided by सोर्स से फाल्ट की लोकेशन तक का total pu reactance.

[@bhuvaneshm7864]

For example given gen capacity-50MVA Ef=10kV having Xg as 1 ohm and given that base MVA for whole system is 100MVA.By the 3rd method which u have explained.SCMVA for gen is (100MVA*10kV*10kV)/(1 ohm *50MVA)...Is it right??

Sir mene 3rd method padha hu but sir apke lecture se bhi bhot Kuchh confusion door ho gya thank you so much sir

[@deeznuts-pf2lv]

In third method you don't even need to find individual MVA/Zpu. Simply take base MVA and divide by sum of all pu values of reactance

[@PriyaSingh-dr2my]

sir, in case Generator ka rated voltage 11kv na ho k kuch or ho then Ef(pu) ki value 1 na ho ke Eg/11 hogi ??

[@GeniqueEducationTeam]

right

Third method is mentioned in Ashfaq Hussain. Whereas I knew the first and last method. One can also find the SC MVA By taking MVA base/X Where X Is the net reactance or total reactance.

[@kalpeshsalunkhe6274]

Sir, in MVA method ...1).is it necessary to keep all equipment at common base ?.... 2)And also.....for some equipment which is given with impedance rather than Only reactance ....do we need to take impedance in MVA/Xeq.... or we just have to take reactance part of it...
