Considering that power lines are operated many times below a rated load current, in this paper an adaptive procedure is presented in order to manage power distribution systems according to dependability or security requirements. In particular, a procedure to obtain an inverse time trip curve by means of a microprocessor, connected to a relay, is presented. The procedure adapts the trip characteristic depending on the conductor temperature, wind speed, emissivity and solar absorbity and is implemented on a microprocessor Rabbit 2200 considering a Drake conductor, 795 kcmil 26/7 ACSR.}, url = {{\url{https://www.sciencedirect.com/science/article/pii/S0378779606002744?casa_token=21NSYv-CizQAAAAA:837EcF8XZT7tULhzILImUV-nT7YfMWEuRahx89aaWd8-7CGxNcvN10zFLsBgD_X0ej0cBa1H}}}, quotes = {... , in [9], in order to predict the thermal behaviour on short and long time horizons, also in the presence of data uncertainties, an interesting approach, based on the use Affine Arithmetic, ...} }
