Hello everyone,

I'm trying to create a simulation model in PSCAD to perform a switching transient analysis. The system is Vacuum Circuit breaker feeding a MV transformer with a cable in between the VCB and transformer.

So far I was able to use the predefined VCB model, and cable as an RLC circuit but not sure how to create the delta side of the three phase transformer as equivalent circuit. Does anyone have experience with how to create the model in PSCAD. I have attached the snapshot of oneline and transformer test report. Any advise or reading material on how to model this is in PSCAD for simulation or how determine the parameters will be really helpful.

(fyi- I'm using PSCAD for the first time)
