1. 1. Partial discharges in cylindrical cavities at variable frequency of the applied voltage

   Författare :Cecilia Forssén; Roland Eriksson; Ron Brammer; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electronic structure; Elektronstruktur;

   Sammanfattning : Measurements of partial discharges are commonly used to diagnose the insulation system in high voltage components. Traditionally a single xed frequency of the applied voltage is used for such measurements as in the Phase Resolved Partial Discharge Analysis (PRPDA) technique. LÄS MER

3. 2. Modelling of cavity partial discharges at variable applied frequency

   Författare :Cecilia Forssén; Roland Eriksson; Hans Edin; Peter H.F. Morshuis; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; partial discharges; measurements; modelling; variable frequency; cavities; disc-shaped; polycarbonate; Electric power engineering; Elkraftteknik;

   Sammanfattning : The presence of partial discharges (PD) in high voltage components is generally a sign of defects and degradation in the electrical insulation. To diagnose the condition of high voltage insulation, PD measurements is commonly used. LÄS MER
