modelAnalysatorAC
Analyze AC voltage, current and power
Extends from Icons.RoundSensor (Icon representing a round measurement device), Modelica.Electrical.Polyphase.Interfaces.TwoPlug (Component with one polyphase electrical port).
Information
Provides mean of total power over one period as well as the following values for each phase:
- RMS of first harmonic of line-to-line voltage
- RMS of first harmonic of line-to-neutral voltage
- RMS of first harmonic of feed current
