Abstract

The increase in volume of embedded generation,
particularly wind farms in the United Kingdom coupled with
change in nature of connected load (growing number of electric
vehicles and domestic PV) will require system operators to look
for ways to reduce network constraints. Increasing the current
carrying capacities of transmission lines while ensuring that
safety margins are not encroached will result in significant
improvements to overall transmission efficiency and reduction in
operational costs. It is possible to increase transmission lines
transfer capacities through monitoring of conductor
temperature in real time; however, there are conditions that will
necessitate limitations. One of these is the effect of conductor
shading (due to trees for example), another is the temperature
overshoot effect (mainly relevant to new conductors running at
90° Celsius). This paper will focus on studying the cooling effect
of rain on conductor ampacity. A close relationship (rain Vs
conductor temperature) often ignored in studies concerned with
ampacity measurements and computation.
