Partial Discharge measurements are very important to determine the condition of electrical equipment. The cause of the partial discharge is not only old equipment but also from set-up errors and insulation problems. In high-voltage equipment such as cables, circuit breakers, bushings and transformers there are generally surface release phenomena due to aging insulation in high-voltage equipment, aging of insulation caused by heat, electricity, ambient and mechanical factors. Liquid insulation as a dielectric material used in high-voltage equipment functions as insulation and heat transfer or cooling. This study aims to determine the surface release characteristics around the surface edge of the Printed Circuit Board (PCB) with a plate electrode model in liquid insulation (mineral oil). PCBs that have epoxy insulating material (FR-4) are one of the basic ingredients used in the isolation of high voltage equipment but have disadvantages due to pollutants. The measurement of partial discharge is carried out using electric and non-electric methods. Electric methods use RC Detectors and HFCT sensors and nonelectric methods with Loop Antenna sensors. Measurement parameters taken include Partial Discharge Inception (PDIV), partial discharge extinction voltage (PDEV), Partial Discharge waveform, Partial Discharge phase pattern and breakdown voltage. This Partial Discharge phase pattern data is presented in the form of a φ-q-n pattern. In oil isolation testing measurements are carried out at voltage levels of 17 kV, 18, kV, 19 kV, and 20 kV for Partial Discharge waveform parameters and Partial Discharge phase patterns. The test results revealed that in the isolation of oil the PDIV value in surface release testing obtained using RC sensor detectors had a higher Vpp value than the air isolation test. Judging from the value of dielectric strength in PCB surface release testing in oil insulation has a higher value compared to air insulation.[/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]HFCT,Loop Antena,Oil insulations,Partial discharge inception,Partial discharge measurements,Partial discharge waveforms,Printed circuit boards (PCB),Release characteristics[/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]HFCT,Loop Antena,Oil Insulation,PCB,Plane-Plane Electrodes,RC detector,Surface Discharge[/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/ICHVEPS47643.2019.9011146[/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]
