Question 9.1: The phase voltage is given by Van = 230 ⌊10°V. For abc phase......
The phase voltage is given by V_{\mathrm{an}}=230|\underline{10}^{\circ}\mathrm{V}. For abc phase sequence, determine V_{\mathrm{bn}} and V_{\mathrm{cn}}.
Step-by-Step
The phase voltage for line a is,
V_{\mathrm{an}}=230|\underline{10^{\circ}}V (9.26)
The phase voltage for line b is,
V_{\mathrm{bn}}=230|\underline{10^{\circ}-120^{\circ}}=230|\underline{-110^{\circ}}V (9.27)
The phase voltage for line c is,
V_{\mathrm{cn}}=230\vert\underline{{{10^{\circ}-240^{\circ}}}}=230\vert\underline{{{-230^{\circ}}}}V (9.28)
