Abstract

The invention discloses a method and system for determining the error measurement function of an automatic verification system, belonging to the technical field of electric measurement. The method of the present invention comprises: using a high-level standard and an automatic verification system to carry out m groups of measurements on the low-voltage current transformer inspection standards, each group repeatedly measures n data, and obtains the mean value of sample data, subgroup coefficients and measurement uncertainty; according to the sample data Mean value, subgroup coefficient and measurement uncertainty, automatic verification system operation control chart; control the automatic verification system to check the low-voltage current transformer, obtain test data, if the test data falls into the automatic verification system operation control chart, determine the automatic verification The system error measurement function is qualified. The invention utilizes the quality control chart of the verification standard and the control chart of the running state of the assembly line to visually record whether the measurement process of the assembly line is in the state of statistical control, so that the running state of the automatic verification system is always under controlled supervision.

Description

technical field [0001] The present invention relates to the technical field of electrical measurement, and more specifically, to a method and system for determining the error measurement function of an automatic verification system. Background technique [0002] Low-voltage current transformers are used for energy metering in 0.4kV distribution lines. In order to ensure the fairness and justice of electricity trade settlement, low-voltage current transformers must pass the verification before they can be installed and put into operation on site. With the rapid development of my country's economy, the demand for electricity in various regions is increasing day by day, and the usage of low-voltage current transformers for metering is also increasing rapidly. The traditional manual method of testing low-voltage current transformers has low work efficiency and high operating costs, and it is difficult to ensure a high degree of consistency between the verification standards and...
