Modelica.Electrical.MultiPhase.Sensors.VoltageQuasiRMSSensor

Information

This sensor determines the continuous quasi RMS value of a multi phase voltage system, representiong an equivalent RMS voltage V vector or phasor. If the voltage waveform deviates from a sine curve, the output of the sensor will not be exactly the average RMS value.

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