Abstract

Gas insulated transmission lines are designed for underground bulk power transmission. They may be used to overcome potential bottlenecks in EHV transmission grids. They are designed for high ampacities and have high overload capabilities. By exploiting the latter, a load scheduling in the grid becomes easier. To do so the thermal status of the GIL has to be known. A temperature measurement system was developed and tested which allows an online measurement of the conductor temperatures during operation, enabling scheduling and handling of overloads
