# Calculation of Transformer Parameters

02/27/2017 12:50 AM

I have a single phase 10 kVA 20kV/110V 50 Hz transformer. primary resistor = 5000 ohms , primary inductance = 10000 H, secondary resistor = 0.2 ohms , secondary inductance = 10 H, Exciting Current 0.5%.

I need to compute PU leakage reactance X12 (or PU Impedance Zpu??), PU Copper Losses and PU No-Load Core Losses.

Can you please provide me with the calculations or a reference?

Sounds a lot like homework, especially with all of those highly convenient values.
