Three-phase series RLC wye load#

block

Block appearance in REPEAT VISION#

 The Three-phase series RLC wye load block is a model of a three-phase star-connected load with phase components connected in series.

 The parameters of phase components (active resistance,inductance and capacity) are determined according to the given powerbased on the assumption of their parameters constancy.

 Capacities can be set as three-phase (then each phase will consume thesame power and the load will be symmetrical) or in phase (then the load will be asymmetrical).
