Abstract
The paper presents a comparison of partial discharge (PD) measurements taken on 140 large power transformers using radio-influence voltage (RIV) meters calibrated in pV according to NEMA 107 Standard and also with the aid of wide-band and narrow-band PD detectors calibrated in pC according to IEC Publication 270. Results are presented in the form of pC/¿V ratios and compared to data from the literature. In conclusion the RIV measuring technique is considered inappropriate for PD measurements on power transformers, although it can be employed to detect the presence of the discharges.
