TEMPERATURE CONTROL METHOD FOR WIRES OF POWER TRANSMISSION LINES Russian patent published in 2015 - IPC H02G7/16 G08B19/02 

FIELD: electricity.

SUBSTANCE: in a temperature control method for wires of power transmission lines using the temperature coefficient α of active wire resistance according to the invention voltage and current are measured in the first position in the power transmission line and voltage and current are measured in the second position in the power transmission line. The measured current and voltage in the first and second positions are synchronised in time with potential joint processing of the above measured values of current and voltage, against the measured current and voltage in the first and second positions the total resistance is determined for the power transmission line between the first and second positions, on the basis of the determined total resistance at a temperature To for the wires of the power transmission line active resistance Ro is determined for the power transmission line between the first and second positions, the current active resistance R is determined in the power transmission line between the first and second positions and against the known temperature coefficient α of the active wire resistance in the power transmission line the current temperature T is determined for the wires of the power transmission line as per the formula T=To+(R-Ro)/(α·Ro).

EFFECT: extended operational capabilities due to continuous control of temperature for the wires in power transmission lines.
