Transformers - winding resistance and leakage reactance

    transformers -- winding resistance and leakage reactance

    Does anyone know what is meant by:
    'determine the combined winding resistance and leakage reactance referred to the primary side'?

    Yes. When you drive a test signal into the primary side of a transformer, the load presented by the transformer is a combination of the magnetizing and leakage inductances of the transformer, along with the winding resistances, and the transformed load on the secondary. Are you familiar with such a model of transformers, and are you familiar how the secondary load impedance transforms across to the primary side?
