Symmetrical Component Method for Relay Protection

Home / Symmetrical Component Method for Relay Protection

The method of symmetrical components is used to simplify fault analysis by converting a three-phase unbalanced system into two sets of balanced phasors and a set of single-phase phasors, or symmetrical components. In oltage and current are more sensitive to electric faults compared to their phase-domain counterparts. For this reason, several protection relays operate on symmetrical components nd many. We must practice these techniques in order to fully understand and feel comfortable with them.
