Good day everyone,

I'm trying to simulate a single phase transformator by using Simulink. I've got the current values: R1 = 3 Ohm R2 = 0.03 Ohm X1 = 6.5 Ohm X2 = 0.07 Ohm Rc = 100k Ohm Xm = 15k Ohm f = 60 Hz Uprim = 2400V Usec = 240V S = 29kVA cos Phi = 0.8

And I've made the current calculations: L1 = X1/2*pi*f = 17,24 mH L2 = X2/2*pi*f = 185.68 uH Lm = Xm/2*pi*f = 39.79 H S = Urms*Irms => Irms = 120.83 A P = Urms*Irms*cos Phi = 23200 W Q = Urms*Irms*sin Phi = 17400 VAr Q>0 so Q = ohms-inductive => QL = 17400, QC = 0

I've made the current circuit and simulated it, but somehow my secondairy output voltage is only at 225Vrms. Can someone explain to me why that's the case? Did do something wrong in my calculations or in my simulation?
