A proposal for an overhead line monitoring system using infrared imaging is presented as a thermal characterization
of a target far from the imaging sensor. The thermal image is
used to measure the clearance from conductor to ground, which
allows the transmission system operators to regulate the power
transmission to prevent possible dangerous events. If the line is
too elongated due to high temperatures, the possibility of electrical sparks with objects near the line increases. Additionally, this
system can detect hot spots in the connectors and ice loads over
the line if the position of the field of view is changed. The design
of this system is described in detail, as well as some simulations
and experimental results are shown to illustrate the capabilities
of the proposed system.
