Hall Effect Gear Tooth Sensors Improvement

Leakage protection has been used extensively in the low-voltage distribution network currently, which enhanced the low-voltage distribution network security and reliability of power supply, but because of its widespread and enormous quantity, the leakage protection regulation becomes very difficult to run, so that the traditional leakage protection control regulatory model can not meet the requirements of smart grid construction, poses a potential threat to the safe use of electricity. This paper proposed the establishment of intelligent supervisory system of leakage protection and energized test leakage protection device action characteristic, the data through wireless remote transmission to the data management center, analysis and judge the working status of leakage protection, According to the risk assessment, put forward the maintenance strategy.
