A three phase balanced star connected voltage source with frequency $$\omega \,\,rad/s$$ is connected to a star connected balanced load which is purely inductive. The instantaneous line currents and phase to neutral voltages are denoted by $$\left( {{i_a},{i_b},{i_c}} \right)$$ and $$\left( {{V_{an}},\,\,{V_{bn}},\,\,{V_{cn}}} \right)$$ respectively and their $$rms$$ values are denoted by $$V$$ and $$1.$$ If
$$$R = \left[ {{V_{an}}\,\,{V_{bn}}\,\,{V_{cn}}} \right]\left[ {\matrix{
0 & {{1 \over {\sqrt 3 }}} & { - {1 \over {\sqrt 3 }}} \cr
{ - {1 \over {\sqrt 3 }}} & 0 & {{1 \over {\sqrt 3 }}} \cr
{{1 \over {\sqrt 3 }}} & { - {1 \over {\sqrt 3 }}} & 0 \cr
} } \right]\left[ {\matrix{
{{i_a}} \cr
