Diagnosis in Analog Electronic Circuits, Electrical Power Systems and Smart Grids

Diagnosis, in its most general meaning, is the process aimed at identifying the causes that have produced a behavior, normally anomalous, in a system of either biological or artificial nature. In medicine, the term has long been commonly used and describes the aim of identifying a disease producing certain symptoms. The concept of diagnosis can easily be extended to a more generic biological context, and has eventually been applied also to technology. In fact, in terms of a machine, it is important tracing back to the causes that have produced an anomaly, typically a fault, or possibly a design error; in any case something that, once identified, must be corrected. For simple systems, a diagnosis can be achieved manually by an expert operator.
