Abstract: The present invention relates to a method for detecting and warning of operational failures. The methodology was developed for hydrotreatment units and more specifically for monitoring pressure loss in hydrotreatment reactors, but it can be applied to any process that benefits from plant monitoring, especially in cases where the evolution of the undesirable event cannot be mapped by known equations. Adaptations for using in other process plants can be carried out by any specialist in that area, it is only necessary to map the variables that must be observed and define the monitoring needs in terms of acquisition interval, as well as the alarm settings that will depend on the dynamics of the process itself.

Abstract: The present invention relates to a system for analyzing the insulation condition of an electrical machine (1), the electrical machine (1) comprising a housing (2), a plurality of supply conductors (3) and at least one grounding branch (5), in which it comprises: at least one scanning module (20) coupled to the plurality of conductors (3); at least one control module (9) coupled to the scanning module (20); and at least one analysis module (21) coupled to the control module (9); wherein the scanning module (20) is configured to inject and measure a plurality of high frequency voltage signals between the housing (2) of the electrical machine (1) and the plurality of conductors (3) and measure a plurality of high frequency currents circulating in the plurality of conductors (3) in response to the injection of each of the plurality of high frequency voltage signals; wherein the control module (9) is configured to control and synchronize the injections and measurements of the scanning module (20) and send the meas
