Cleaveland Price has released its LineScope® Line Sensor for application on distribution and transmission power lines. It is available from 4kV through 115kV, measures voltages and currents with 0.5% accuracy, produces power quality calculations, and captures over-current events. Unlike similar sensors, the LineScope® is a battery-free device powered from line voltage, which allows operation without a line current requirement. The device is comprised of two pieces – a sensing head that connects directly to the power line and a wireless receiver at ground level. The sensor data is available at the wireless receiver via DNP protocol for easy integration in to existing SCADA and smart grid systems.
