Thanks Safi Ullah. I have shared all lectures that I had made, however if you have difficulty in understanding any topic or problem, please mail me at profkhannazir@gmail.com
FOA thanks for this lecture. I was trying to solve probs from exercise of Fifth Edition of Stephen J Chapman. Can you please explain me diff between Full load voltage and no load voltage i guess it is 2.7 problem i somehow get the answer and tried to understand by my self but still im not able to differentiate it to solve voltage regulation confidently.
The concept of Full Load is slightly misleading. When nothing is connected to the secondary terminal of the transformer, the voltage measured at the terminal is called no load voltage (actuall it should have been called no current voltage, because in case of open circuit, no current flows in the secondary). Now if we connect a variac (variable resistance) at the output , and keep adjusting the resistance, till such time that the current flowing in the secondary is equal to the maximum rated/designed current of tranformer. This is called full load condition. At this point the voltage accross the load (variac) will be called full load voltage. This voltage will be less than the no load voltage because of drop in the windings/line. A good transformer should have less drop, and bad one will have more. So good one will have low value of voltage regulation ((Vfull - V noload)/Vnoload)
Generally when we are talking of electric supply, the electric transmission system comes in mind (WAPDA), where high voltage is transformed to low voltage at the grid stations or at distribution transformers (11KVA to 220V in our cities). In this case the transformer primary is high voltage( 11KVA) and secondary is low voltage(220V). But at the generation station it is opposite, where low voltage is changed to high voltage. There the tranformer primary is low and secondary is high.
thanks for excillent explanation😍😍😍😍😍😍😍
Thanks dear. Best wishes
Excellent explanation 👍
Glad you liked it
very helpful videoes.thank you sir
Welcome dear
hi teacher
i want at you to share most lecture of electrical machines.you lacture very usefull for mee.
thank yiu teacher

I need your guidance for part a of 2.7

Excuse me Sir , How did we get about the values of Req. & Xeq. ?
Read the book. Also watch this th-cam.com/video/uJP_rFndPtU/w-d-xo.html
sir why we take referred primary side as high voltage side and referred secondary side as low voltage side 🤔

Dear sir , i have a question in 2.5 part (e) here already given core loss and cupper loss, why i need to again extract copper and core loss ??
where it is given? please give time reference where given
Sir can sent the solution of electric machinery sixth edition pdf step by step please.
Sorry dear. I'm using 4th ed.
link of this video in urdu ?
Sorry don't have.
