How to perform an open circuit test on a transformer

0 votes
I am trying to perform an open circuit test in PLECS but I am struggling to get realistic values. An example is the current when there is no load is coming back more than 20A with a 240V supply.

I have attached an image of my setup. Where am I going wrong?

There is no image attached...
Don't know why it wasn't but it is now...

The turns ratio is 1:10 and the source is connected to the low voltage side.

Hi, unfortunately it's not clear from the schematic how you are representing the impedance (any copper/core losses). Can you include your actual model, or at least show what's inside the subsystem?
