Learning and understanding three-phase systems would be incomplete without learning and analyzing unbalanced three-phase systems. An unbalanced three-phase system is not a rare thing in power transmission and distribution. When we are dealing with either: 1. Balanced three-phase system 2. Unbalanced. .
A three-phase system is balanced if all the line loads are equal to each other. If one of the loads is increased, then it will be an unbalanced system. Why? Because that line will draw more current. .
Even if we are dealing with three-phase systems, we can still use mesh and nodal analysis. Of course KCL and KVL are also useful. Observe the circuit. .
