Many methods have been tried to detect PD for cable joints installed in a manhole. Among them, an attempt is made to detect PD by transient earth voltage (TEV) sensor attached inside a metal bucket which is brought down into the manhole. This PD detection method can be used to diagnose the cable joint condition and to ensure safety of the personnel before entering the manhole. This paper presents simulation of electromagnetic wave emitted by PD and induced surface current flowing on the surface of the metal bucket to enhance the PD detection sensitivity. The simulation was made with a three-dimension finite difference time domain (FDTD) simulation software (CTC Co.; MAGNA TDM version 8.3) by changing the bucket depth, diameter, aperture angle and material, as well as excitation frequency of PD source and distance from the bucket. As a result, it was found that an optimal metal bucket shape providing the highest detection sensitivity in terms of the surface current is bucket with 0° aperture angle (cylindrical shape), outer diameter 300 mm, bucket depth 150 mm for iron material with 1mm in thickness under the circumstances of the manhole in which the cable joints are installed.[/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]Cylindrical shapes,Detection sensitivity,Electrical phenomena,Excitation frequency,Finite-difference time-domain simulation,High voltage cable,simulation,Three dimensions[/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]FDTD,metal bucket,partial discharge,simulation,TEV[/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.2018.8535615[/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]
