Abstract:
    The invention is about a synthesized error detecting method of secondary circuit electricity power measurement and its equipment. The method is: the power meter tests the power information, meanwhile, the power metering equipment placed in the power meter measures the electric energy information and the voltage information of PT start point of a secondary circuit at the same time, and sends the voltage information to the metering equipment through its annex via wire or wireless transmission / reception method in real-time. The measured energy difference between the two measurement devices is the synthesis error of the secondary circuit, which provides another kind of test method for measuring electric energy.
