EMTP/PSCAD

Hello everyone,

I'm trying to create a simulation model in PSCAD to perform a switching transient analysis. I need help in how to model the cable and transformer to study switching transients on transformer. THe following if the transformer information available from data sheet.
1500kVA ; 12470kV-480Y/208V; Delta-Wye; 60Hz; %Z-6.17%
Capacitance
HV to LV & GND - 1570pF
HV to GND - 220pF
HV to LV - 1350pF
LV to HV & GND - 3760pF
LV to GND - 2400pF
LV to HV - 1360pF

Xm (ohms/phase) - 36841 (magnetising)
Rc(ohms/phase)-136484 (magnetising core)
Xp (henries/phase)-0.021 (primary)
Xs(henries/phase)-0.020
No load losses - 3418 Watts
I excitation - 0.875% Amps
Load Loss-13330 Watts

I have a cable after the breaker for which I am entering information available from data sheet in for of RLC circuit. But not sure if I am modeling the transformer correctly.

I was wondering if anyone can share more examples on similar source, breaker, cable and transformer. PSCAD preferred.

Check out lecture 37 for transformer modeling.

PSCAD help manual has detailed information about transformer modeling. Check that and post if you don't understand specific thing.
