Abstract
The combination of a temperature sensor and an inclination sensor or the combination of a temperature sensor and a tension monitor properly positioned in conjunction with an energized electrical conductor produces outputs that are dependent on the conductor's average temperature in real time. A transmitter is used to communicate this information in real time to a central location such that up to optimal or maximum power transmission is feasible through the conductor while maintaining a safe clearance to the ground. This allows for close monitoring of thermal expansion resulting from increased load as well as varying environmental conditions.
