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)

Study on the Detection of Single and Dual Partial Discharge Sources in Transformers Using Fiber-Optic Ultrasonic Sensors

Photonics
Partial discharge is a fault that occurs at the site of insulation defects within a transformer. Dual instances of partial discharge origination discharging simultaneously embody a more intricate form of discharge, where the interaction between the ...

Partial Discharge Behaviour of a Protrusion in Gas-Insulated Systems under DC Voltage Stress

Energies, 2020
High reliability, independence from environmental conditions, and the compact design of gas-insulated systems will lead to a wide application in future high voltage direct current (HVDC) transmission systems.

A Building Block to the Design of Partial Discharge Free HV and MV Cables: Modeling Defects and Discharge Inception Voltage

IEEE Access
It is well assessed that partial discharges, PD, are one of the major causes of MV and HV cable system breakdown, thus investigating partial discharge phenomenology and harmfulness is a key topic in relation to electric asset component reliability ...

Localization of Partial Discharges in Hydrogenerators by Ozone Emission

Energies
We suggest a new method of localization of partial discharges in high-power electrical systems. Ozone in a hydrogenerator is produced by chemical reactions induced by partial discharges in the stator region.
