Abstract:

This paper proposes an evaluation method and a system based on the simulation of partial discharge patterns to evaluate the performances of the digital partial discharge measuring instruments. Referring to the structure of partial discharge calibrator, the system can physically simulate and output PD patterns using arbitrary waveform module to evaluate such performances as partial discharge pattern recognition. These partial discharge patterns are obtained from mathematical models or experiments on artificial defects or online measurements and saved in a database. The structure of the system and the characteristic of the generated charge sequences are discussed. The potentiality of the developed characterization system has been proved in the evaluation of the advanced features of some digital PD measuring instruments.

Key words: Characterization system, calibration, partial discharge (PD), digital PD measuring instrument, pattern classification
