ENEL experience of insulating gas gas-insulated substations. | National

The nature of the sites where ENEL (Italian Electricity Board) is planning to install future substations calls for a considerably greater number of such units than in the past. Consequently, ENEL has decided to standardize and upgrade gas-insulated substations and their components. This paper presents ENELpolicy for achieving these ends.
