Expert systems are used for the evaluation of the actual state and future behavior of insulating systems of electrical machines and equipment, especially for the evaluation of discharge activity in high voltage insulation by partial discharge measurement. Several rule-based expert systems were developed in the High Voltage Laboratory of the Czech Technical University in Prague for these purposes. The complex system for the evaluation of-partial discharge measurement including software and hardware facilities has also been developed. Two expert systems for the evaluation of partial discharge activity work in this complex evaluating system: a rule-based expert system performs an amplitude analysis of partial discharge impulses for determining the damage of the insulation system, and a neural network is used for a phase analysis of partial discharge impulses to determine the kind of partial discharge activity.
