Abstract
An overhead conductor monitoring device includes a simulation conductor designed to have thermal characteristics similar to those of the overhead conductor. The simulation conductor is placed in the same ambient atmosphere as the overhead conductor and is selectively heated by a coil embedded within the simulation conductor. The power supply to the coil is computed by a microcomputer to be the same as the power of the overhead conductor. Temperature sensors are placed in or on the simulation conductor to monitor the temperature thereof. As the temperature of the simulation conductor increases, the power of the overhead conductor is recomputed to reflect changes in the characteristics of the overhead conductor. An alarm signal is generated if the temperature of the simulation conductor exceeds a predetermined temperature and theoretical values of overhead conductor power can be supplied microprocessor to determine the effects on the temperature of the overhead conductor.
