Research on the online remote calibration technology of the digital meter

Digital power meter is widely used in smart substation, the workload of On-site calibration of digital power meter exponential growth. How to solve a lot of power table fieldwork accurately and easily make the remote online calibration study became the Necessary research project. This paper carried out for the digital meter calibration technology research, analyzes digital power meter Line Inspection technology, design a viable digital meter remote calibration systems and solutions. This system can effectively reduce the digital power meter artificial scheduled inspection project, and even obviate manual inspection, and it can reduce the inspection cost and improve reliability and efficiency.
