ELECTRONIC ELECTRICITY METER

摘要

electric measurement technology. SUBSTANCE: multiple-function electricity meter designed for measuring electrical energy in single- and three-phase electric circuits for various purposes including computer-aided energy-resource measurement and control systems is built around signal processor and has controller, as well as voltage and current sensors built around pulse-width transducers noted for high pulse repetition frequency. Due to such application of computer capabilities controller and sensors form optimal automatic-control system ensuring computer-aided correction of sensor characteristics to minimize their error and to adapt them to destabilizing factors. EFFECT: enhanced accuracy and stability, enlarged functional capabilities, improved stability of meter characteristics. 1 dwg
