Abstract

The invention discloses an electronic transformer error measurement device and method, and the method comprises the steps that a synchronous photoelectric clock source transmits second pulse signal toa merging unit and a data collection module of a to-be-measured electronic transformer when an upper computer transmits a test instruction; the on-line monitoring module receives a network message data frame sent by the merging unit of the electronic transformer to be detected after receiving the second pulse signal, and analyzes the network message data frame to obtain detected electric energy sampling data of the electronic transformer to be detected; the data acquisition module acquires electric energy data of a standard electronic transformer after receiving the second pulse signal so asto acquire reference electric energy sampling data; and the error calculation module performs asynchronous measurement processing on the measured electric energy sampling data and the reference electric energy sampling data, and calculates the error of the to-be-measured electronic transformer according to the measured electric energy sampling data subjected to asynchronous measurement processingand the reference electric energy sampling data subjected to asynchronous measurement processing.

Description

technical field [0001] The present invention relates to the technical field of high-voltage measuring equipment, and more particularly, relates to an electronic transformer error measuring device and method. Background technique [0002] Since the intelligent construction of the power grid, electronic transformers have made great progress in the unified and strong smart grid goal proposed by the power grid construction. An electronic transformer is an electrical device consisting of one or more current or voltage sensors connected to a transmission system and a secondary converter to transmit a quantity proportional to a "measurement" for measuring instruments, meters and relays Protective device or control device use. The principle of the electronic transformer error measurement device is to use a standard transformer to compare with the electronic transformer to be tested to calibrate whether there is an error in the "measured amount". [0003] The scenarios and reasons ...
