The UHF sensors have shown a great advantage in the detection of partial discharge because they are capable to detect partial discharge signal online without the need of prior shutdown of the high voltage apparatus. This paper discuss the measurement of partial discharge in air insulation by using the designed UHF double layer bowtie antenna with modified antenna wings edges. The double layer bowtie antenna was used to detect PD based on EM waves induced by PD in air insulation. The PD measurement results obtained by using the designed double layer bowtie were compared with PD measurements results obtained by using the RC detector which was taken as a comparison sensor. The characteristics of PD induced EM waves measured by RC detector and double layer bowtie have been investigated. The PD measurement was performed at three applied voltage levels namely, 5 kV, 6 kV and 7kV. The PD measurement results have shown that the higher applied voltage, the high Vpp magnitude for PD waveform, PD charge magnitude and PD number in both negative and positive half cycle.[/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]Bow-tie antennas,Corona discharges,Diagnostic techniques,High voltage apparatus,Insulation system,Partial discharge signal,PD-induced EM wave,Ultra-high frequency[/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]bandwidth,bow-tie antenna,partial discharge,return loss,UHF,VSWR[/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/ICEEI47359.2019.8988866[/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]
