[0002] With the development of social economy, the society has a growing demand for the power market and higher requirements. In particular, a huge gap has appeared in the power market in recent years. In order to ensure people's livelihood and daily electricity consumption, power supply companies need to monitor all industrial electricity consumption in real time and conduct reasonable load control based on the power grid and the actual power consumption of customers. To meet the new load control management needs of the Southern Power Grid, the most basic thing is to accurately measure the power load. Only by obtaining accurate power consumption data can there be a basis for load control management.

[0003] It is easy to measure the power load on site, but it is unrealistic to read it on site, and it is impossible to monitor the power load in real time. At the same time, if the data measured by the on-site instrument is simply used, it is easy to have inaccurate data, which will also affect the use of customers. Therefore, the load control management of the power grid should adopt an independent measurement and monitoring system. Because the independent measurement and monitoring system is added, more space is required on the cabinet to install the measurement and monitoring system. Utility Model Content
