Continuous quasi current RMS sensor for polyphase system

Extends from Modelica.Icons.RoundSensor (Icon representing a round measurement device), Polyphase.Interfaces.TwoPlug (Component with one polyphase electrical port).

Information

This sensor determines the continuous quasi RMS value of a polyphase current system, representing an equivalent RMS current vector I or phasor. If the current waveform deviates from a sine curve, the output of the sensor will not be exactly the average RMS value.

I = sqrt(sum(i[k]^2 for k in 1:m)/m)
