Theory of Transformer on Load and No Load Operation ...· This component produces the alternating magnetic flux in the core, so it is watt-less; means it is a reactive part of the transformer source current. Hence I μ will be in quadrature with V 1 and in phase with alternating flux Φ. Hence, the total primary current in a transformer on the no-load condition can be represented as:
