Based on demonstration and more comprehensive analysis, this paper expounds views and understanding of the author on six questions, namely, the different concerns of electric energy measurement in different scenarios, the need to make better use of big data to build a novel method of electricity meter inspection, the new challenges faced by dynamic electric energy measurement research, the need to focus on super-harmonic electrical energy measurement, the inadvisability of equating electric energy measurement devices with electricity meters, and the difference between measurement precision and measurement accuracy, which is intended to promote the development of relevant research and a clearer understanding of relevant measurement methods and concepts.
