The Designing And Realization Of The Programmed Calibrator Of Three Phases Watt-hour Meter

The calibrator of three phases watt-hour meter is the standard equipment for calibrating watt-hour meters, and important for our country抯 watt-hour meter calibrating. Tt is the indispensable standard facilities for the departments of electric power, the factories of producing watt-hour meters and the departments of standard detecting. Now, the principles and technology of designing and producing this detecting device has been ripe, the important problem is how to improve it抯 automatic level and accurate grade of calibrating. In this thesis, the author discussed the principles of the calibrator of three phases watt-hour meter and gave its producing and using conditions in our country. He lie stress one introducing a kind of designing, realizing scheme of calibrator of programmable controlled watt-hour meter, and analyzed the technology function of the scheme. This scheme can come up to advance our countries?standards in the automation level and the accurate grace of detecting.
