Abstract

The invention discloses a universal test platform for dynamic performance of electrical measuring equipment, which is composed of a control system, a dynamic signal power source, a high-dynamic performance multifunction electric parameter standard meter, a universal data receiving unit and an electrical measuring equipment detection meter position, wherein the control system is used for executingman-machine conversation, sending an operation command and receiving and managing test result data; the dynamic signal power source is used for outputting dynamic voltage and current signals whose amplitude, frequency and phase can be changed continuously according to a set size and a set rate; the high-dynamic performance multifunction electric parameter standard meter is used for measuring electric parameters such as voltage, current, power, frequency and phase in a high precision mode in a dynamic test signal condition and measuring each harmonic content in a test signal waveform and the phase thereof in a high precision mode; the universal data receiving unit is used for receiving result data outputted by each kind of tested electrical measuring equipment, carrying out conversion and decoding to form a unified private data format and sending the data to the control system; and the electrical measuring equipment detection meter position is used for placing the tested electrical measuring equipment.

Description

technical field [0001] The invention relates to a general test platform for the dynamic performance of electric measuring equipment, which belongs to the technical field of electric energy measurement. Background technique [0002] At present, the accuracy index of electrical measurement equipment (generally refers to the multi-function meter with electrical parameter measurement function, various power distribution terminals, etc., and the harmonic energy meter with harmonic analysis and measurement function, power quality analyzer, etc.) The assessment is carried out under steady-state signal conditions, which cannot reflect the measurement accuracy of the equipment in a rapidly changing dynamic signal environment. Therefore, it is currently technically impossible to grasp the actual measurement performance of the equipment under special operating conditions where the line signal is dynamic. . [0003] According to the needs of actual applications, electrical measuremen...
