Multiplier is harmonic backdrop electronic energy meter measurement error resulting main links

Focuses on the electronic energy meter's internal structure and working principle, through the electronic meter error characteristics and frequency characteristics of the theoretical analysis, pointing out that the multiplier is a harmonic backdrop electronic energy meter measurement error resulting main components. Secondly,  electric transformer  wave modulation type time division multiplier (TDM) works to mathematical analysis, the establishment of electronic energy meter measurement error mathematical model. Multisim simulation software to build electronic energy meter  air circuit breaker , and verify that the simulation results of the simulation model was built correctly. Simulation model based on indicators in different circumstances specific harmonic simulation analysis, simulation waveform.
