Radiometric Partial Discharge Detection: A Review

open access: yesEnergies, 2023
One of the most common failures or breakdowns that can occur in high-voltage (HV) equipment is due to partial discharges (PDs). This occurs as a result of inadequate insulation, aging, harsh environmental effects, or manufacturing flaws. PD detection and

Partial discharge Source Calibration of Radiated Partial Discharge Signals

open access: yes2022 2nd International Conference on Advance Computing and Innovative Technologies in Engineering (ICACITE), 2022
Based on the IEC 60270 guideline, a galvanic quantification along with free-space radiometry (FSR) method are used to measure partial discharge (PD) simultaneously. The PD source is a floating-electrode emulator type that was custom built.

Classification of Superimposed Partial Discharge Patterns [PDF]

open access: yesEnergies, 2021
Phase resolved partial discharge patterns (PRPD) are routinely used to assess the condition of power transformers. In the past, classification systems have been developed in order to automate the fault identification task. Most of those systems work with

Domain-Adaptive Transformer Partial Discharge Recognition Method Combining AlexNet-KAN with DANN [PDF]

open access: yesSensors
The changes in operating conditions of a power transformer can cause a shift in the distribution of partial discharge data, leading to the gradual generation of unlabeled new data, which results in the degradation of the original partial discharge ...

Modeling partial discharge phenomena

open access: yesIEEE Electrical Insulation Magazine, 2020
Measurements of partial discharge (PD) activity are a commonly used technique to diagnose the health of insulation material within high voltage plant. The definition of PD is relatively broad, it is generally defined as a localized or confined discharge ...
