  • Abstract
    This paper presents results of PD test at elevated frequency of supply. Particular attention was given to the discharges that occur in moist pressboard layers immersed in transformer oil. The effect of moisture content on the PD activity was investigated based on the observation of the PD quantities and the characteristics of the PD distributions. Data obtained from the PD test is presented in phase-resolved analysis (PRA) and voltage different analysis (VDA).
