Buildings.Electrical.DC.Sensors.GeneralizedSensor
Sensor for power, voltage and current
Information
Ideal sensor that measures power, voltage and current. The two components of the power S are the active and reactive power. As this sensor is configured to measure DC power, the reactive power is always zero.
Extends from Buildings.Electrical.Icons.GeneralizedSensor (Icon representing a generalized sensor that measures voltage, current and power), Buildings.Electrical.Interfaces.PartialTwoPort (Model of a generic two port component with phase systems).
