Wireless powerline sensor
From Wikipedia the free encyclopedia
A Wireless powerline sensor hangs from an overhead power line and sends measurements to a data collection system. Because the sensor does not contact anything but a single live conductor, no high-voltage isolation is needed. 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.
In the photos on the right, an antenna on the sensor transmits data to a communication device attached to a nearby utility pole. The communication device gets power from the 240 volt utility line in a residential neighborhood. The device has two antennas. One antenna collects data from the sensors, and the other antenna forwards the data to the electrical utility control center over cell phone service.
The primary purpose of a powerline sensor is to measure current, however, some sensors 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
- Energy management system
