The Current Quasi-RMS Sensor component measures the continuous quasi-RMS value of polyphase current.

If the current waveform deviates from a sine curve, the output of the sensor will not be exactly the average RMS value.

$I_{\mathrm{rms}}\=\sqrt{\frac{1}{m}\sum _{k\=1}^m{i}_k^2}$

$i\=i_p\=-i_n$

$v\=v_p-v_n\=0$
