Beschreibung
Zusammenfassung:The 'partial discharge pattern recording technique' is applicable to electrical insulation field measurements, particularly if combined with disturbance rejection and nonconventional pick-ups. Electromagnetic disturbances are eliminated by filtering in the time domain (impulse noise gating) and/or in the frequency domain (down-mixing). PD patterns not only help to identify the defect type but also serve to evaluate the efficiency of a disturbance rejection procedure.< >
