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

---

A. The difference is very close based on the working of motors, generators and transformers. As the transformer has no rotating parts, the losses are very low. (0.4 Mark)

B. You have given a few theories about lightning arrestors of electric lines. Lightning arresters are very important for high-voltage lines because the consumer's home appliances are damaged when lightning strikes the high-voltage lines. (1.5 Marks)

C. The actual current of the generator is found to be correct. Any generator must not use 80% of its actual load current or engine damage. (2 Marks)

D. Your generator rating is correct according to load. If you purchase a generator with 20% additional load, the specified electrical loads can be powered. (1.5 Marks)

E. The photo of you building a lightning arrester for your home would have been nicer if you moved it a little further. The higher the lightning arrester is placed in the house, the more effective it will be. (3 Marks)

A lightning arrester provides safety in the event of a lightning strike within a radius of about a hundred meters from where it is installed. So install lightning arresters at high places in the house and stay safe. Better homework would have been done if the pictures had been presented more beautifully. Good luck to you.
