Answer / aniket

three phase supply is used
1.to for higher load
2. more than 3 phase ie 6 phase make alternator complex and
losses in alternator increses,more copper is required.

Answer / piyush chaturvedi

Three phase balance supply system is the best suited system considering 3 phase loads as well as 3rd Harmonics in generator windings. A star connected load at generation end makes power free from 3rd harmonic whereas 3 phase balance supply makes system more reliable.

what is surge impedance loading and it's significant in power system?
