Active/Reactive Power (Watt/ Var) Transducer S3(T)-WRD-3AT-165A4GN is applicable to all kinds of single three-item systems, and can accurately measure even unbalanced systems. The design principle is to measure the instantaneous power parameters of various input waveforms using accurate "time-sharing multiplexer" operation processing. After the measured transient variable voltage signal is adjusted and converted by the oscillation circuit and the measured current signal is adjusted by the amplitude, the multiple oscillation circuit is used to generate the square wave signal of the scale ratio. The measured voltage and current signal is processed by the oscillator and the modulator, and then integrated to produce the signal by the amplifier, which is proportional to the power output.
