Abstract: With the development of social economy,people increasingly high demands on power system reliability of power supply, 10kV distribution line as a major power supply network in power system to be a task in situ distribution of power, coverage and distribution lines,and the terrain that surrounds the complex, the lack of effective monitoring measures,leading to frequent 10kV distribution line failure.10kV distribution line after the adoption of Automation,with the distribution of the data collection and monitoring function, it can effectively monitor the type of fault, fault of 10kV distribution line, reduce troubleshooting time for the maintenance personnel, improve power supply reliability.
