Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

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)
