Description

technical field [0001] The invention relates to the fields of electric energy detection and instrumentation, and more particularly relates to a 0.02-level installed standard meter for a transformer-type three-phase smart electric energy meter verification device and a system and method for calibrating using the meter. Background technique [0002] Electric energy has become an indispensable and important energy source for the survival and development of human society. Almost all human activities are closely related to electricity, and the electric energy meter is a direct meter for detecting electric energy usage standards. How to ensure the calibration of electric energy meters? The accuracy and efficiency of the test, and efforts to improve the calibration efficiency of the electric energy meter have become problems that need to be solved urgently by the measurement and testing departments at all levels. In order to maintain the reliability of electric energy metering devi...

AI Technical Summary

Problems solved by technology

Ordinary standard electric energy meters are designed to work in a laboratory environment, and cannot work normally due to environmental influences such as temperature, humidity and electromagnetic interference on site

Moreover, the conventional high-precision standard meter is generally large in size, and requires multiple wirings when verifying the device, and the operation efficiency is low. The ordinary standard electric energy meter is not suitable for use in the field environment, which is also a test for the verification device of the electric energy meter.
