Analysis of the Method and Principle of Measuring the Average Power of Equipment Based on DC Power Analyzer

Abstract

Abstract To solve the problem that it is difficult to accurately measure the average power of equipment with large instantaneous power change, this paper analyzes the principle of equipment power change and the mechanism of measurement error and proposes a reliable average power measurement method based on the idea of calculus. Through test verification, compared with the common three-measurement average methods, the uncertainty of the results calculated by the method proposed in this paper is reduced, and the results are accurate and reliable, which can reflect the real power of the equipment and meet the requirements of the test and test support.
