Wireless powerline sensor

A Wireless powerline sensor hangs from an overhead power line and sends measurements to a data collection system.

[1] Overhead power line monitoring helps distribution system operators provide reliable service at optimized cost.

[2][3] 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.

In some systems, powerline sensors may transmit information on the high voltage conductor itself rather than by transmission of a radio signal.
