Introduction of per day lectures what i will be teaching on per day basis lectures and what is important for gate ies and interview point in transformer

1) Introduction of Transformers (in Hindi)

Here i have introduced with the basics laws that is faraday and lens law which plays a major role in transformer.

2) Basic Laws( Lens and Faraday) (in Hindi)

Phasor groups are mostly asked in interview and gate 2014 question also came from this its and easy topic i explained it each and every connection that can exist except zigzag connection as its not asked anywhere and well if u understand only 2 you can understand full lecture for any doubt please follw the comment i will help you at my best

12) Phasor Groups of Transformers (in Hindi)

Autotransformer, its advantages, disadvantages, applications in machine amd power syatem point of view how winding are connected with each other which is lv and which is hv which is common.

9a) Autotransformer Advantages, Disadvantages and Applications (in Hindi)

Derivation thats important for numericals and its copper saving Derivation, component of power transfer, copper comparision.

9b) Autotransformer Basic Derivations (in Hindi)

Transformer connection through numerical these are best numerical 1st numerical help to develop the base concept and 2nd numerical is asked in GATE and it is one of the best numerical so i shared with you comment below for doubt

9c) Autotransformer connection through numerical (in Hindi)

Magnetising current phenomenon in the steady state how the curve is in magnetising current and core flux curve and the function harmonics how it plays an important role in making the waveform sinusoidal.

15a) Magnetising current phenomenon in steady state

When Magnetising current is sinusoidal what will happen to core flux. Also what type of coonections are there in transformer that are affected by 3rd harmonics and how to recover my sinusoidal flux

15b) Magnetising current phenomenon in steady state
