Abstract
The gas-insulated transmission line (GIL), which is a
replacement of an overhead line in some special environments has
been used because of its high capacity, low losses and no
electromagnetic interference.
A mathematical thermal model for predicting the steady state
temperature distribution inside and outside GIL is investigated by
merging two techniques to get rid of using sensors inside the GIL
cable.
The finite element analysis involving formulation and solution
of the heat conduction equations has been done. During the solution
of the heat conduction equations of the proposed model, a
numerical study based on energy conservation equation using
MATLAB © programming is performed to determine the bulk
temperatures of the insulating gas inside the cable.
The obtained results are validated against experimentally
measured values under the same conditions. The validation
indicates that the results are very close to the experimental
measurements
