摘要：

Field trials were carried out on five power transformers ranging in size from 18 to 1000 MVA and in voltage from 25 to 400 kV. The tests helped to define what will be required of a portable UHF monitor for power transformers. Results highlight the capabilities of the UHF technique as well as some of the challenges to be overcome and should be helpful to anyone intending to use UHF sensors to locate PD or arcing in transformers.
