Partial Discharge (PD) measurement is a method used to determine the vacuum condition to detect early leakage from Vacuum Circuit Breaker (VCB). This paper presents the floating shield potential of an interrupter related to PD inception voltage (PDIV) as function of the internal pressure. PD phenomena were investigated regarding floating shield potential affected by variations in the shield to grounded plate distance. The discharge mechanism was also discussed in term of impact electron multiplication and ion drift in the vacuum. The result showed that lowering the shield to the grounded plate distance would shift the curve to a lower pressure region. At pressures less than 3 Pa, the discharge is found to obey Townsend-like mechanism, and change to streamer-like mechanism with increase in the pressure.[/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]Degree conditions,Discharge mechanisms,Electron multiplication,Partial discharge measurements,PD inception voltage,Vacuum circuit breaker,Vacuum condition,Vacuum interrupters[/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][/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/ICEPE-ST.2019.8928783[/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]
