Circuit Analysis of 3 Phase System

 

The electrical system is of two types i.e., the single phase system and the three phase system. The single phase system has only one phase wire and one return wire thus it is used for low power transmission. The three-phase system has three live wire and one returns path. The three phase system is used for transmitting a large amount of power. The 3 Phase system is divided mainly into two types. One is Balanced three phase system and another one is unbalanced three phase system.

The balance system in one in which the load are equally distributed in all the three phases of the system. The magnitude of voltage remains same in all the three phases and it is separated by an angle of 120º. In unbalance system the magnitude of voltage in all the three phases becomes different.
