WebNov 27, 2024 · The phasor or vector diagrams for a transformer on resistive, inductive, and capacitive loads are drawn by taking flux Φ as the reference. Let, V 1 = Primary supply voltage. E 1 & E 2 = Primary and secondary induced emf's. I o = No-load primary input current. I 2 = Primary current. I 2 = Secondary current. WebFor a parallel circuit, the voltage is used as the reference phasor, because the voltage is common to all parts of the circuit. Later you will see that transformers have a magnetic flux which is common to the input and output of the transformer, and so the flux becomes the reference phasor.
