Love this guy... reminds me of college professors I couldn't understand in the 80s but understand now lol

[@educationalconsultant2739]

Waoo sir so nice way of describing ,, all concepts clear,,thankyou so much

[@stantasstic]

I wish these videos could be translated or captioned to English. These lectures are so useful that I wish I could understand Hindu. But oh well, here I am trying to follow up and cling onto the few instances that he uses English.

Sir isme motor load k Sath back emf nhi lgega kya?

[@DrAfrozAlam]

Please read description of this video lecture. At time 21:15, please add EMF in series with reactance for all the three motor loads.

[@buddhikatilakaratne4489]

sir, could you please give a per unit lesson by English. it is very helpful us.

[@huzaifahassan1935]

sir which book should i refer with ur lectures??

[@DrAfrozAlam]

You may read Hadi Saadat, Kothari Nagrath etc. Actually, I prepare my own lecture notes instead of following any particular book.

[@razanayaz5376]

Sir, let's assume that the question did not say that the base MVA is anything. In that case, will the formula for finding the per unit impedance of the transformer disregard the MVA part?

[@DrAfrozAlam]

In that case, you need to assume a common MVA base. Generally, the highest MVA rating among the various power system elements.

[@sharadr]

Ye to hamare senior they

[@SubhaEE]

Ye kon sa subject hai...??machine start kar diye hai. Kya sir?

[@maneeshmahur1391]

A 90 MVA, 11 kV, 3-Phase, generator has leakage reactance of 25%. The generator supplies two motors through transformers and transmission line as shown in fig. The transformer T, is a 3-phase transformer, 100 MVA, 10/132 kV, 6% reactance. The transformer T₂ is composed of 3 single phase units each rated at 30 MVA, 66/10 kV, with 5% reactance. The connection of T₁, T₂ are as shown. The motor are rated at 50 MVA, and 40 MVA both 10 KV with 20% reactance. Taking generator rating a base draw reactance diagram and indicate reactances in per unit. The reactance of line is 100 Ohms.? SIR ISKA BHI SOLUTION DE DIJIYE.
