A field integral detecting system of a three-phase electric energy measuring system of an electric distribution network mainly consists of a portable adjustable three-phase voltage, an electric energy meter verifier, a three-phase active electric energy meter field measuring circuit and a three-phase active electric energy meter standard measuring circuit. According to a V-V connection method or a Y-Y connection method, a primary loop of a high-voltage current transformer of the field measuring circuit is connected with a standard high-voltage current transformer in series, and a standard voltage transformer is connected with a voltage transformer loop of the field measuring circuit in parallel. With the system, the comprehensive error is minimized, and the accuracy of the measuring device is improved through the integral test. The system directly, truly and accurately measures the overall operating performance of the electric energy measuring system of a three-phase power supply system of an electric distribution network. |
