A Wireless powerline sensor hangs from an overhead power line and sends measurements to a data collection system. The sensor, installed simply by clamping it around a conductor, powers itself from energy scavenged from electrical or magnetic fields surrounding the conductor being measured.〔 Overhead power line monitoring helps distribution system operators provide reliable service at optimized cost. Some powerline sensors may transmit information on the high voltage conductor itself rather than by transmission of a radio signal. () () … ==Measurements== The primary purpose of a powerline sensor is to measure current, however, some can either directly measure or derive other data such as: *Conductor temperature *Ambient temperature *Inclination or the amount of line sagging *Wind movement *Electric fields *Power Generation *Distribution and Consumption of electricity 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wireless powerline sensor」の詳細全文を読む スポンサード リンク
