A wide range of transducers to measure all forms of active 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 – Watts.
Double Output/Dual Output Var/Reactive transducer
