Solving of some Problems with On-Line Mode Measurement of Partial Discharges

Blog Article

This paper deals with the problems discussing the transition from off-line diagnostic methods to on-line ones.Based on the experience with commercial partial discharge measuring equipment a new digital system for the evaluation of partial discharge measurement including software and hardware facilities has been developed at the Czech Technical University Brass Flare T-Union in Prague.Two expert systems work in this complex evaluating system: a rule-based expert system performing Game Room an amplitude analysis of partial discharge impulses for determining the damage of the insulation system, and a neural network which is used for a phase analysis of partial discharge impulses to determine the kind of partial discharge activity.

Problem of the elimination of disturbances is also discussed.
