摘 要：One of the main tools for monitoring the condition of high voltage equipment is the measurement of partial discharges(PD).The electromagnetic(EM)radiation originated from this degradation phenomenon can be captured by various types of ultra‐high fre-quency(UHF)antennas carefully designed and optimised for specific frequency ***,the presence of environmental noise may limit the use of this *** types of monopole antennas normally used in UHF PD measurement have been evaluated in order to validate the performance of a novel separation technique of EM ***,a new separation technique based on the energy ratio of the captured signals was developed,considering noise *** results revealed that the new technique allows an adequate separation,even when three sources act simultaneously.
