Problems solved by technology
According to standard requirements, the electromagnetic environment monitoring of power transmission and transformation projects is generally only carried out in good weather, while the audible noise and radio interference of power transmission and transformation projects vary greatly with environmental factors such as weather, and long-term test statistical analysis is required
[0003] At present, the systems for testing the electromagnetic environment of transmission lines are all single-point short-term test systems. The data obtained by this system need to be collected and counted manually to obtain a long-term multi-point data, which greatly increases the researcher's Labor intensity, at the same time, the accuracy and reliability of the data is not high
