InHand Networks Low-current Harvesting, High-precision Sync, High-rate Wave-recording, Live Installation InHand Wireless Overhead-lines System Smart power distribution is an important sector of smart grid. One great challenge faces the operation team of distribution networks is how to quickly and accurately locate the faulty section when power line faults, especially low-current ground faults occur. Existing distribution automation, feeder automation, and fault indicating technologies have the problems of high investment, requiring power off for deployment, low accuracy, etc. InHand Wireless Overhead-lines System, the smart distribution lines monitoring system launched by InHand Networks, can accurately identify the type of power line faults and quickly locate the faulty section based on innovative technologies of high-precision measurement and high-speed waverecording of line currents, thus significantly shorten response and processing time of power line faults, improve power supply reliability. The Overhead Line Sensor is the acquisition unit and core sensing unit of the system, applicable to 10kV overhead distribution lines. With innovative low current energy harvesting and wireless communication technologies, the Overhead Line Sensor can submit monitoring data in real time to keep the power utility operational staff updated on the operation status of power lines. With big-data based comprehensive analysis of distribution lines status, the system can generate line status analysis, including line faults, line loads, energy quality, etc., and provide solid data support for the structural optimization of distribution network.
