Answer Posted / shubham
3 phase power is the most economical solution.
Firstly as the number of phases increase accordingly the
number of conductors, insulators etc will increase which
will be costlier. And secondly as number of phases increases
power does not increase linearly i.e. total power supplied
in N phase system is not equal to N(power supplied by single
phase).It is their vector addition. Power v/s phase graph
will take a shape like the saturation curve of transformer
core. So at higher phases cost wise input is high but power
wise output is not that high.
That's why 3phase system is the optimum solution
