Information

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

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

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