Symmetrical Components
The symmetrical component is a methodology that is applied to the Solution of Polyphase Networks. Positive, Negative, and Zero Sequence Components there are three sets of independent components in a three-phase system: positive, negative, and 0. zero is for both current and voltage. Positive sequence voltages (Fig. 1) are supplied by generators within the system and
