ELECTRIC ENERGY METER ON-LINE DETECTION METHOD

摘要

Provided is an electric energy meter on-line detection method, applicable to on-site calibration, periodical inspection and faulty meter calibration. An electric energy meter to be detected is connected to a standard electric energy meter by series connection for current and parallel connection for voltage; a power pulse signal is read from the electric energy meter to be detected and is then input into the standard meter; an error is displayed on the standard meter, so that the electric energy metering error of the electric energy meter to be detected can be read out directly. The present invention makes full use of existing devices and incorporates multiple functions on one meter. The electric energy meter need not be dismantled, and the detection can be performed on line, thereby reducing the workload of periodical inspection on the electric energy meter and calibration on the faulty meter, improving working efficiency, and reducing cost.
