Abstract :
The ground-mat dimensioning of two or more neighboring interconnected substations is treated. A set of calculation procedures, using the decoupled method, is given. It is shown that the electric neighborhood of nearby substations depends on the space constant (or characteristic length) of the ground circuits interconnecting them. A simple procedure is presented for determining the suitable number of aluminium-conductor steel-reinforced ground wire spans near a substation, which are needed to allow a reduction of the ground grid conductor extension
