Thermal calculations of gas insulated transmission lines GIL based on thermal networks

Temperature measurement system for gas insulated transmission lines for an effective load scheduling of underground bulk power transmission

“…Core of this calculation is a calculation tool which is based on thermal networks. This tool models the thermal conditions for each individual application and enables static and dynamic calculations [12]. Fig.…”

Gas insulated transmission lines (GIL) with spare phase - new concepts for investment reductions

“…GILs have been designed for high currents. Depending on the application, a GIL system may carry between 2500 A (directly buried) and 4000 A (tunnel or outdoor installation) of continuous current [14]. The application of a thermal rating system allows even in the case of directly burying currents of up to 4000 A for operating hours with higher currents [15].…”
