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.
Cleaveland/Price’s LineScope® is a highly accurate three phase power monitoring system for use on circuits up to 138 kV. The system consists of three conductor-mount LineProbe sensors and a data consolidating RTU3212 that can be housed in a CommBridge communication node, a customer’s communication node, or integrated into a Cleaveland/Price ADMO or PTAD switch controller.
- Power quality monitoring, reporting RMS current, RMS voltage to an accuracy of 0.5%, phase angle, power angle, power factor, real power, and reactive power
- Fault indication with fault direction, impedance/distance to fault, and fault magnitude to 32 kA peak reported
- Harmonic distortion analysis
- Line temperature monitoring
- Monitoring bi-directional flow lines
- Open tap monitoring
- Phase alignment comparison between system taps
- Voltage reduction
- End of line monitoring
- Auto line transfer
- Analog input for capacitor bank control
- Voltage certification for NERC PRC-005
The maintenance-free LineScope® is powered by line voltage, rather than line current, giving the system visibility on lightly loaded lines.
