A  wide  range  of  transducers  to  measure  all  forms  of  reactive power,  in  both  balanced   and  unbalanced,  single  or  3 phase  system.They utilize the well prove "time division multiplication" method of measuring instantaneous power over a wide range of input waveforms.The  circuit  diagram  shown   measured  voltage  is  modulated  by  circuit
of   an  oscillator.  Square  wave  pulses  from  a  multi-vibrator circuit, with a   mark - space  ratio varied   by  the  measured  voltage  and  amplitued  by the measured current, are fed to an integrator an output amplification circuit. The dc signal produced is then directly proportional to power input - Vars.
