Description

technical field

[0001] The invention relates to an automatic data collection and processing instrument of a power system, in particular to a power distribution monitoring and measuring device with a time synchronization function. Background technique

[0002] With the development of the national economy and the improvement of people's living standards, the requirements for power quality of smart appliances, smart meters, and advanced industrial automation equipment continue to increase. Electric energy is different from other products. The generation, transmission, transformation, distribution and use are completed at the same time, and the equipment in each link is connected in a system. With the development of the economy, the power system is becoming larger and more complex. A fault somewhere in the power grid or serious power quality problems such as harmonic pollution may occur at any time. Finding and determining the source of the fault or pollution will become a new t...
