| Abstract: | The frequency response (FR)
characteristics of the ultra-high frequency (UHF) sensors used for detecting partial
discharge in GIS are analyzed by the antenna theory and measured in laboratory. It is
shown that the calculated results are in good confirmity with the measured ones. In
addition, the sensitivities of the capacitive sensors as function of frequencies in UHF
band and the influences of the sensor constructions on the frequency response
characteristics are studied. |

| Keywords: | UHF sensor frequency response characteristic |
