Claim:
1. A method of controlling the amount of electrical power delivered to an electric transmission line (conductor), comprising: applying an electrical signal to the conductor; detecting a reflection signal reflected from a reflection point on the conductor; using processing equipment to perform the following: calculate the reflection propagation delay of the reflected signal; calculate the present length of the conductor based on the propagation delay; receive data representing the present tension of the conductor; receive data representing conductor reference parameters, comprising a reference tension value and reference length value both taken at a reference temperature value; receive data representing conductor characteristic parameters, comprising conductor weight, span length, elasticity, thermal expansion, and plastic deformation; and calculate the average temperature of the conductor based on the present length, present temperature, reference parameters and characteristic parameters; delivering average temperature data to a transmission capacity controller; and dispatching power to the conductor based on the average conductor temperature data.
