Partial discharge (PD) signals generated by defects in a transformer insulation can be captured through measurement instruments and they may be used, after preprocessing, to discriminate the PD Sources. Some of the artificial defect models, such as: corona, internal cavity and surface discharge in air are developed in the laboratory. These defect models are put in parallel under a high voltage stress. The PD signals stemmed from these sets of multiple PD sources are captured. In this paper six bandpass filters (with two MPD 600 devices) are used for feature extraction of these signals. For PD signals discrimination, the Density-Based Spatial Clustering of Applications with Noise density (DBSCAN) method is employed with two freedom parameters which resulted in an accurate discrimination of types of partial discharge sources.

Spectroscopic study and numerical simulation of low-pressure radio-frequency capacitive discharge with argon downstream
Tanisli, Murat; Rafatov, İsmail; Sahin, Neslihan; Mertadam, Sercan; Demir, Suleyman (Canadian Science Publishing, 2017-02-01)
In this study, the characteristic properties and plasma parameters of capacitive radio frequency (RF) argon (Ar) discharge and supplementary discharge at low pressure are investigated with optical emission spectroscopy (OES). The wavelengths of spectral lines from OES are obtained between 650-900 nm. Using OES lines and related experimental data, the electron temperatures for different RF power, flow, and measurement periods are determined. Eventually, the properties of plasma including the electron tempera...
Partial Discharges Pattern Recognition of Transformer Defect Model by LBP & HOG Features
Anşin, Berfin; Phung, B. Toan; Blackburn, Trevor R. (2019-04-01)
Partial discharge (PD) measurement and identification have great importance to condition monitoring of power transformers. In this paper, a new method for recognition of single and multi-source of PD based on extraction of high level image features has been introduced. A database, involving 365 samples of phase-resolved PD (PRPD) data, is developed by measurement carried out on transformer artificial defect models (having different sizes of defect) under a specific applied voltage, to be used for proposed a...
Online monitoring of transformer through stream clustering of partial discharge signals
Anşin, Berfin; Phung, B. Toan; Blackburn, Trevor (2019-05-01)
The general method for identifying the partial discharge type in a power transformer is based on their fingerprints in the form of phase-resolved discharge patterns. In the case of multiple defects, traditional clustering methods can be applied for separation of active sources. However, such an approach is impractical for online real-time monitoring due to the very large data size. In this paper a new method using stream clustering is introduced. The method separates the active sources by processing the sig...
Critical analysis of matching schemes in capacitively coupled discharges
Demokan, O (Institute of Electrical and Electronics Engineers (IEEE), 2003-10-01)
It is shown that, in capacitively coupled radio frequency discharges, the amplitude of the discharge current may not have a unique value for a matching network designed to yield the maximum power transfer. The condition, which may lead to this uncertainty, is derived to avoid the possible, undesired mode of operation.
Multi-frequency contactless electrical impedance imaging using realistic head models : single coil simulations
Gürsoy, Doğa; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2007)
Contactless electrical impedance imaging technique is based upon the measurement of secondary electromagnetic fields caused by induced currents inside the body. In this study, a circular single-coil is used as a transmitter and a receiver. The purpose of this study is twofold: (1) to solve the induced current density distribution inside the realistic head model resulting from a sinusoidal excitation, (2) to calculate the impedance change of the same coil from the induced current distribution inside the head...
