Hi, can anyone tell us about magnetic circuit of three phase transformer?
Transformer Magnetic Design
Three Phase Transformer Phase Angle and Magnitude Distortion due to Unsymmetrical Core Reluctance Seen by Each Phase
In 3 leg three phase transformer, do we get some phase voltage manitude and angle change due to un-symmetrical reluctance seen by every different phases? The phase at the middle leg is not distorted because fluxes come from both rear legs equally in magnitude. But voltage and angle of rear legs change somewhat because the other two phases' flux come to rear legs in different magnitudes. So this distorts both magnitude and angle of voltage.
Is there a such thing? And how much is this effective?
