Abstract
A method for monitoring the electric insulation status of a piece of equipment for a medium-voltage or high-voltage electric system, which includes the following steps: acquiring detection data indicative of the behaviour of said piece of equipment, said detection data including a time sequence of measured discharge values related to partial-discharge events observed at subsequent observation instants in time; basing on said detection data, calculating stochastic data indicative of the electric insulation status of said piece of equipment, said stochastic data including probability values related to the observed partial-discharge events and calculated as a function of one or more characteristic parameters related to said partial-discharge events; basing on said stochastic data, calculating estimated data indicative of said one or more characteristic parameters related to said subsequent observation instants.
