Palm fatty acid ester (PFAE) oil and 2H-O8 oil are palm based vegetable oil that have been considered as insulating oil. This paper discusses PFAE oil and 2HO8 behavior due to partial discharge (PD) occurrence compared to mineral oil. The comparison includes PD repetition number n, average PD charge qav, and generated gases. In the first experiment, 10 kV to 20 kV step voltages are applied to the insulating oil for 120s each step. n and qav are measured. In the second experiment, 17 kV is applied to the insulating oil for 2 hours and generated gases are measured after that. The results show that n and qav of mineral oil are less than PFAE and 2H-O8 oil. Mineral oil has an ability to suppress bubble diffusion better than PFAE oil and 2H-O8 oil due to its higher kinetic viscosity number. Accumulative PD charge in PFAE oil and 2H-O8 oil is much higher than mineral oil and generates more gases, especially H2. For a single PD charge, mineral oil generates more H2 than PFAE oil and 2H-O8 oil. Mineral oil has more C-H bond which is dissociated in lower energy. For certain ageing time, mineral oil gives better performance regarding to PD occurrence than PFAE oil and 2H-O8 oil. © 2014 The Institute of Electrical Engineers, Japan.[/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]2H-O8 oil,Better performance,Bubble diffusion,Dissolved gas analysis,Fatty acid esters,Kinetic viscosity,Partial discharge characteristics,PFAE oil[/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]2H-O8 oil,dissolved gas analysis,insulating oil,mineral oil,partial discharge,PFAE oil[/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/ISEIM.2014.6870786[/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]
