Hi all,
assuming a three-phase supply (25k Vrms phase-phase) supplying a three-phase load. I connected a voltage and current measurement block having a base voltage of (25k Vrms phase-phase) and base power of
(1M VA 3 phase). With the pu voltage and current measurements into a active and reactive power measurement block,the output of the power measurement block must be multiplied by a gain of 2/3 in order to have the correct active and reactive power measurement.My question is why 2/3?
All these are simulated in SIMULINK/MATLAB.Thanks..

alvin
