In recent years, the growing penetration of the electrical energy vector in a large number of products and industrial sectors through the multiplication of electrical devices (machines-converters-storage) leads to complex systems with restrictive requirements in terms of operational safety and availability and which can be very critical for certain applications. For example, the automotive sector saw the implementation of the ISO 26262:2011 standard in 2011, which would guarantee the functional safety of a system embedded in the vehicle. Likewise, the ED-12C and DO-178C standards concern the analysis of safety for avionics. It should be noted that this expansion of the electrification of machines and objects in different sectors of human activity has been accompanied by a dazzling increase in the production of electrical machines and static converters throughout the world. This new situation accentuates the need for systems (devices and components) for the conversion and transformation of energy which, while not being totally immune, have qualities of intrinsic availability despite the occurrence of a fault. Thus, these increasingly strong requirements for availability and safety of systems, imply new requirements in the research effort on the methods and methodology of diagnosis/prognosis of electrical devices accompanied by a review of their design in order to structurally integrate availability through their capacity to be tolerant of certain defects. Indeed, diagnosis consists of detecting, locating and identifying faults allowing supervision systems to act effectively by applying one of fault tolerance scenarios, namely accommodation, reconfiguration or restructuring depending on the degree of severity of the fault. The prognosis for its part predicts the future operating state of the equipment concerned which is the subject of an international standard (ISO, 2004). Thus, prognosis is considered a key process in maintenance strategies. It is in this context that GREAH and IRSEEM combine their forces by constituting a multidisciplinary project team capable of dealing with many of the multiple aspects of the issue of safety and availability of electrical energy conversion and transformation devices.
