PTME: a new expert system application for power transformer troubleshooting and maintenance

The scope of this paper is the introduction of PTME (Power Transformer Maintenance Expert), a new expert system application, which can be used as an efficient decision making tool in a sophisticated problem as the optimization of maintenance procedures (preventive, predictive and corrective) of Power Transformers. The expert system comprises a knowledge base and a set of production rules that produce results through the application of forward/backward chaining reasoning. The knowledge base set of data is generally characterized by a complex structure in a tree form, with three main branches that correspond to preventive, diagnostic and corrective maintainance respectively. PTME has been developed at TEI of Athens and can be used both for engineering and educational purposes.
