Three-phase series RLC delta load#

block

Block appearance in REPEAT VISION#

 Three-phase series RLC delta load block is a model ofa three-phase series triangle-connected load whose interphasecomponents are connected in series.

 The parameters of phase components(active resistance, inductance and capacity) aredetermined according to the given power based on the assumptionof their parameters constancy. Capacities can be set asthree-phase (then each phase will consume the same power and the load will be symmetrical) or in phase (then the load will be asymmetrical).
