An unbalanced system is analysed as the superposition of three balanced systems, each with the positive, negative or zero sequence of balanced voltages. When specifying wiring sizes in a three-phase system, we only need to know the magnitude of the phase and neutral currents.
Power engineering software is a software used to create models, analyze or calculate the design of Power stations, Overhead power lines, Transmission towers, Electrical grids, Grounding and Lightning [clarification needed] systems and others. It is a type of application software used for power engineering problems which are transformed into ...

The neutral carries current if the loads on each phase are not identical. In some jurisdictions, the neutral is allowed to be reduced in size if no unbalanced current flow is expected. If the neutral is smaller than the phase conductors, it can be overloaded if a large unbalanced load occurs.
The system rotates without requiring the application of any external force or couple, other than that required to support its weight. If a system is initially unbalanced, to avoid the stress upon the bearings caused by the centrifugal couple, counterbalancing weights must be added. This is seen when a bicycle wheel gets a buckled rim.
Many transmission lines are intrinsically an unbalanced format such as the widely used coaxial cable. In such cases the circuit can be directly connected to the line. However, connecting an unbalanced circuit to, for instance, a twisted pair line, which is an intrinsically balanced format, makes the line susceptible to common-mode interference.
The development of CPC-based power theory by Leszek S. Czarnecki was initiated in 1983 when he challenged the correctness of existing power theories as applied to single-phase linear, time-invariant (LTI) loads with nonsinusoidal voltage, and next, he revealed the existence of a scattered current, and invented a method of reactance compensation.
