If the three phase transformers supplied a load of 70 kva


Compute the answer of the following question

Question- Three identical single phase 2400/240 v, 50 Kva transformers are connected to work as 3 phase 4160/240v transformers. Each transformer has Req = 1.42 ? Xeq 1.82?

Part 1- State how you connect the transformers

Part 2- If the three phase transformers supplied a load of 70 kva at 240v and a 8.0 Power factor lagging. Calculate the required primary voltage.

Part 3- Calculate the efficient neglecting core loss.

I want help to find the efficient neglecting core loss.
