Ultrahigh-frequency detection techniques appear as a feasible alternative to traditional methods owing to their inherent advantages such as the capability to detect PDs online and to locate the piece of equipment with insulation problems in substations and cables. In this paper, four antennas are thoroughly studied by means of their theoretical and experimental behavior when measuring electromagnetic pulses radiated by PD activity. The theoretic study of the band of frequencies in which the pulse emits and the measurement of the parameters S11 are complemented with the frequency response and wavelet transform of a set of 500 time signals acquired by the antennas, and the results are analyzed in detail.10application/pdfeng© 2013 IEEEAntenna measurementsDielectric measurementspartial discharges (PDs)UHF measurementsultrahigh-frequency(UHF) antennas, waveletsresearch articleTelecomunicaciones10.1109/TIM.2012.2223332open access9325-May941IEEE Transactions on Instrumentation and Measurement62AR/0000016982
