UHF method becomes more popular because of its higher S/N ratio. UHF sensors are the most important part of UHF method PD measurement. This paper deals with the PD measurement using several UHF sensors installed on 66 kV GIS model with needle protrusion on the conductor as its PD source. Sensitivity verification for external UHF sensors were examined based on CIGRÉ Task Force 15/33.03.05 to ensure that the sensors can fulfill the minimum requirement for PD measurement in GIS. Then, the effects of sensor position in the circumferential and effect of the sensor distance to PD source on PD magnitude were measured by the external UHF sensors. Result of this experiment are compared with simulation using FDTD method. Finally, based on this result, we recommend the best position of external UHF sensor applicated on GIS. © 2012 IEEE.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]angle position,Gas insulated switchgears,High voltage apparatus,Insulation conditions,Minimum requirements,Partial discharge detection,Sensitivity verification,UHF sensor[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]angle position,gas-insulated switchgears,partial discharges,sensitivity verification,UHF sensor[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/CMD.2012.6416241[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
