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.
