A wide range of transducers to measure all forms of reactivepower, 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, witha mark - space ratio varied by the measured voltage and amplitued bythe measured current, are fed to an integrator an output amplification circuit. The dc signal produced is then directly proportional to power input - Vars.
