3 phase generator performance is seen here

The performance of a 3 phase generator can be measured quite accurately. And from that it is quite easy for an engineer to compare one phase generator with another. Some generators are better than competitors. Most appliances that have to work in an environment with single phase power supplies will need a phase converter, and the three phase generators you see on construction sites and in home workshops are very necessary for the engineers and workmen who are there. But some of these generators are giving equipment operators more performance than others. Because some converters will not transfer the whole potential of the current into the three phase tool.
