Symmetrical Components


In power systems, it is a common occurrence that there are unbalanced voltages and currents on the distribution side of the grid. But these voltages and currents might be unbalanced anywhere through the grid in the case of a Fault, most commonly a short circuit fault.The simplest method to calculate the before mentioned quantities is a method termed "symmetrical per phase" technique and the concept is known as Symmetrical Components given by Fortescue's Theorem. It is also known as the "Three-component method".It can be described as:

An unbalanced system of 'n' phasors can be resolved in 'n' system of balanced phasors called the symmetrical components of the original system.
