Study on the Effect of Void Geometry and Location on Electric Field Distribution and Partial Discharges in HVDC Cables [PDF]
E3S Web of Conferences, 2023 Nowadays HVDC transmission systems are preferred over HVAC systems because of their less power loss and high reliability. In the HVDC cable transmission system, there is a problem of Partial Discharges (PD) occurring due to cavities of the dielectrics in

Partial discharges characteristics study in XLPE cable insulation with multiple defects [PDF]
Омский научный вестник, 2021 The paper simulates the electric field intensity picture in the cable with one and several defects. Modeling has shown that the presence of several closely spaced defects does not lead to an increase in the electric field intensity in comparison with

Monitoring of Partial Discharges in Cable Insulation and Cable Head Using Acoustic Method [PDF]
Archives of Acoustics, 2022 The article presents the application of Acoustic Emission (AE) method for detection and registration of partial discharges (PD) generated in medium voltage (MV) cable isolation and MV cable head.

Study power of partial discharges to voltage intensity in XLPE-insulated cables [PDF]
Омский научный вестник, 2020 The article investigates partial discharges (PD) as a mechanism of insulation destruction. Some of the known mathematical models of insulation aging take into account the effect of partial discharges. These models are based on the dependence of partial

Partial Discharge Analysis and Simulation Using the Consecutive Pulses Correlation Method
Energies, 2021 The behaviour of partial discharge as consequences of an alternating current (AC) is already well defined. AC partial discharges have completely different behaviour, background physics and parameters than partial discharges (PD) under direct current (DC)
