    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%
    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)
    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.
