Hi @shadow04, thank you for participating in the Industrial Electrical Homework. We have assessed your Homework post , and the below captures our assessments.

---

A. Correctly identify two transformers in the picture. But it would be nicer if you judge the transformer by picture. Transformers can be identified by looking at the patches on the primary and secondary coils. The turn ratio of your transformer is correct.

B. You have written the various parts of the power transformer in short form. LT and HT bushings indicate the primary and secondary sides of the transformer.

C. Small-size transformers are used in the distribution area. They are used for single-phase lines at low load. These are step-down transformers.

D. A 6000 KVA or 6 MVA transformer should be purchased for a 5000 KW load. But remember that 80% of any transformer's total rating must be used in the load. This is a very important matter.

E. You have not mentioned the unit of the transformer's rating. eg 33 kV or 415 volts. A single use of rating would have been a better presentation.

F. The rating of the 2.5 MVA transformer in the above topic and the result of this point will be the same because both the transformers have the same rating. Intelligent students will understand. I hope you understand.

G. The power factor is for the consumer using the higher load. If the value of the power factor is low, the power is wasted, so the power companies set a standard value. I hope you understand.

H. The main difference to distinguish between transformers is to know the primary and secondary voltages. You didn't write the main difference. I hope you understand.

Thank you very much for participating in Industrial Electrical Homework. You will apply the learning from the lessons in real life. Transformers are very important in industrial electrical. Good luck to you.
