A Wireless powerline sensor hangs
from an overhead power line and sends measurements to a data collection system.
Because the sensor does not touch anything but a single live conductor, no
high-voltage isolation devices are needed. The sensor is installed simply by
clamping it around a conductor. The sensor 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
Measurements
The primary purpose of a powerline
sensor is to measure current, however, they can monitor other operating
paramers such as:
Conductor temperature
Ambient temperature
Inclination or the amount of line sagging
Wind movement
Electric fields
