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. WebDuring asymmetrical voltage conditions, the zero-sequence flux of a core-type transformer returns outside the core, through an air gap, structural steel, and a tank. Thus, the natural zero-sequence inductance L0 (without delta winding) of such a core-type transformer is usually very low (typically 0.5 pu < L0 < 2 pu) compared with a three-phase ...
