This paper presents research results related to measurements of partial discharges (PD), which may occur in oil insulation systems of electric power transformers. Three measuring methods were considered: electrical (apparent charge - IEC60270), acoustic emission (AE) and ultra-high frequency (UHF) method. Research works have been proceeded under laboratory condition. PD were generated using special apparatus and spark gap configuration for surface PD modeling. Measurements were performed simultaneously for each of the regarded methods and were repeated for selected supply voltage levels. The electrical and UHF methods measurements were made using MPD measuring system from Omicron. The AE method measurements were made using a piezoelectric transducer, which was installed on the outer transformer tank wall. Comparative analysis of signals gathered during research works was made. Possibilities of application of the three considered PD detection methods for electric power systems with oil insulation were proposed in the paper.
