Partial Discharge Pulse Sequence Analyses-A New Representation of Partial Discharge Data

11th International Symposium on High-Voltage Engineering (ISH 99), 1999
Computer-based partial discharge (PD) data acquisition and analyses are common in use. Over the last two decades, there has been tremendous growth in PD data processing to extract information. There are efforts made to make data banks of different PD signature patterns based on $\phi-q-n$ measurements on insulation models.

Novel Self-Organizing Probability Maps Applied to Classification of Concurrent Partial Discharges from Online Hydro-Generators

Energies
In this paper, we present an unprecedented method based on Kohonen networks that is able to automatically recognize partial discharge (PD) classes from phase-resolved partial discharge (PRPD) diagrams with features of various simultaneous PD patterns ...

Fault Indicators of Partial Discharges in Medium-Voltage Systems

Advances in Electrical and Electronic Engineering, 2013
The safety and reliability of the electricity system, these are the two basic keywords present in the energy sector. One of the ways to improve the overall security of the electricity system is to reduce the failure rate of transmission lines.
