Fault diagnosis of electrical systems using Interpreted Petri nets

This paper deals with a diagnosis based on interpreted Petri nets. It introduces the problem of energy interruption on electrical systems, which is a phenomenon of discrete nature where lost of the electrical energy and disconnections of several elements characterize it. Also, it presents a method for obtaining the diagnosis based on interpreted Petri nets and error interpreted Petri nets; the diagnosis step determines and locates faults occurring within electrical systems, i.e. it indicates which electrical component faults and specifies the kind of fault that occurred.
