Homework Statement
I have a step down transformer (6 : 1)
Copper Loss of 110W at full Load
Primary Coil: I = 3.33A R = 0.35 Ohms Power Loss = 4W
Secondary Coil: I = 20A R = 0.265 Power Loss = 106W
Power Drawn Over the Primary = 75W
9kVA Transformer
Homework Equations
The Equations i have are:
E1/E2 = N1/N2 = I2/I1
Power Loss = I^2 x R
The Attempt at a Solution
- No Load Current is 5% less than Full Load Current
- Primary Copper Loss is less than 1/400 of full load copper loss
Your help will be appreciated
Thanks
