Features of Temperature Monitoring of Overhead Power Transmission Lines with Insulated Wires

  • A. P. VikharevEmail author

When monitoring the temperature of insulated wires, the temperature is measured on the surface of the insulation rather than the conductor. The insulation is made of cross-linked polyethylene with low heat conductivity, which leads to a significant temperature difference between the conductor and the insulation surface. A method of calculating the temperature of the conductor from the temperature measured on the insulation surface is described. The permissible surface temperatures of 20 and 35 kV SIP-3 wires that allow controlling the line loading are determined.
