Description

technical field [0001] The invention relates to the field of meter verification, in particular to a method for automatic verification of three electrical meters. Background technique [0002] The verification of the three electrical meters (ammeter, voltmeter, power meter) is very extensive in practical applications, not only the number is large, but also the process is complicated. Since most of the three electrical meters are pointer meters, the verification method of pointer meters is usually to analyze and calibrate the pointer meters by visually observing the difference between the pointer scale readings and the standard input signal, specifically: reading by human eyes The data of the tested meter, and manually adjust the signal source according to the information read by the verification personnel to make the tested meter point to the verification point, and then manually record and calculate the verification results. One of the main problems of this traditional veri...

Problems solved by technology

One of the main problems of this traditional verification method is the low accuracy, poor reliability, and poor repeatability of the readings displayed by human eyes, and the human subjective influence is relatively large.

At the same time, the calibration data calculation of voltage, current and power meters is cumbersome, and the calibration personnel spend most of their time on the pointer and data processing during the calibration process, so the labor intensity is high and the calibration efficiency is low.
