How can we model the current transoformer for phase wires in multism?

Hi Hammad,


If you want to model an ideal current transformer with this equation, Is=Ip(Np/Ns) you can use an current controlled current source which is located in Sources group under the Controlled Current Sources family.   After you placed this part on the work area, you can double click on it and enter the gain which is your turn ratio.

Tien P,

 

Thanks for the tip.  I had not thought of that approach.

could you explain how to model the current transformer as what will be the input to the current controlled current source and where to place the burden?
