Cleaveland Price has released a new class of high voltage line sensors for transmission power lines.
LineScope® Line Sensors are a wireless sensor that provides real time three phase power monitoring for use on high voltage circuits up to 115kV. It measures voltage and load current with 1% accuracy, captures over-current fault events and produces power quality calculations such as watts, VARs, power angle, power factor and THD. Unlike other sensors, the LineScope® Line Sensor is a battery-free device powered from line voltage, which allows operation without a line current requirement and can be easily installed with a hot stick on an energized line. 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. With this new release of the transmission class wireless sensor, the LineScope® Line Sensor is now available for use on power lines from 4kV through 138kV.
