Help in PSCAD - Transformer Modeling
(OP)
Can you please help model this transformer in PSCAD?
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 as the transformer model in PSCAD requires this.

RE: Help in PSCAD - Transformer Modeling
about 20*3/100=0.6 kV.
Zb=20^2/10*1000=40000 ohm
Irat=10*1000/20=0.5 A
Zk=0.6*1000/0.5=1200 ohm[3% from Zb]
The leakage reactance X1=1200 ohm max.
L=1200/2/PI()/50=3.82 Henry only
So check one more time the data-it is here some
inconsistence.
