A review of current knowledge of electrical discharges that do not completely bridge the electrodes. Discharge detection, since 1945 and the use of new high voltage dielectrics, has grown into an indispensable tool for the evaluation of modern insulation. Topics covered include the behavior, detection and measurement of discharges, the choice of detection method and procedure, the location of discharges, and discharge detection in practice.

Practical Partial Discharge Measurement on Electrical Equipment Accessible reference dealing with (partial discharge) PD measurement in all types of high voltage equipment using modern digital PD detectors Practical Partial Discharge Measurement on Electrical Equipment is a timely update in the field of partial discharges (PD), covering both holistic concepts and specific modern applications in one volume. The first half of the book educates the reader on what PD is and the general principles of how it is measured and interpreted. The second half of the book is similar to a handbook, with a chapter devoted to PD measurements in each type of high voltage (HV) equipment. These chapters contain specific information of the insulation system design, causes of PD in that equipment, off-line and on-line measurement methods, interpretation methods, and relevant standards. The work is authored by four well-known experts in the field of PD measurement who have published hundreds of technical papers on the subject and performed thousands of PD measurements on all the different types of HV equipment covered in the book. The authors have also had relationships with PD detector manufacturers, giving them key insights into test instruments and practical measurements. Sample topics covered in the work include: Physics of PD, discharge phenomena (contact sparking and vibration sparking), and an introduction to PD measurement (electrical, optical, acoustic, and chemical) Electrical PD detection (types of sensors), RF PD detection (antenna, TEV), and PD instrumentation and display Off-line and on-line PD measurements, general principles of PD interpretation, and laboratory PD testing of lumped test objects PD in different types of HV equipment (power cables, power transformers, air insulated metal-clad switchgear, rotating machines, gas-insulated switchgear, and more) For HV equipment OEMs, users of HV equipment, or employees of companies that provide PD testing services to clients, Practical Partial Discharge Measurement on Electrical Equipment is an essential reference to help understand general concepts about the topic and receive expert guidance during specific practical applications.

PARTIAL DISCHARGES (PD) — DETECTION, IDENTIFICATION AND LOCALIZATION Explore state-of-the-art partial discharge measurement techniques In Partial Discharges (PD) — Detection, Identification and Localization, a team of distinguished electrical engineers delivers a comprehensive treatment of the behavior, modeling, measurement, monitoring, localization, and evaluation of partial discharges. It includes coverage of all major advancements in the field that have occurred over the last few decades. It also discusses partial discharge phenomena, detection methods, and strategies for analyzing and processing collected data. Mechanisms of insulation failure are explored, as is the denoising of partial discharge measurement data and the localization of partial discharge in large, high-voltage equipment. Non-electric principles and procedures are discussed, and the book offers a variety of tables, figures, and photographs to illustrate the concepts discussed within. Partial Discharges(PD) also provides: A thorough introduction to the physical behavior of partial discharges, including their causes and classification Comprehensive modeling of partial discharge behavior, including classical and dipole discharges Practical discussions of the measurement of partial discharges, including the electrical method, partial discharge decoupling, and pre- and post-processing of partial discharges In-depth examinations of the monitoring of partial discharge behavior, including methods and realization Perfect for electrical engineers engaged in electrical power engineering, Partial Discharges (PD) will also earn a place in the libraries of research and development specialists employed in the manufacturing, quality testing and operation of electrical systems.

High-voltage transformer is the most critical and expensive component in a power system network in order to ensure the stability of the system. Partial discharge (PD) detection is a technique widely used for high voltage equipment insulation condition monitoring and assessment. PD phenomenon causes gradual deterioration of the insulating materials, sometimes over a period of several years, leading perhaps to eventual failure. Detecting PD in power transformers is vital both in industries and utilities to avoid damage of high-voltage equipment. The objectives for this work are: To detect and analysis the PD activity using acoustic sensor (piezoelectric sensor) and capacitive sensor in natural palm-oil and to compare the sensitivity of the two sensors. The capacitive sensor and PZT sensors were immersed in palm oil tank fitted with two steel electrodes which were connected to range of high voltage (0-15KV) from high voltage source, the detecting signal that gained by the acoustic and electric sensors would pass through high pass filter to eliminate the noise range below 100-KHz then it is connected to the oscilloscope by wiring connections means.

Partial Discharges are symptoms of insulation degradation that continually promotes the deterioration of the insulation condition, eventually leading to permanent failures. The PD event itself is not dangerous but it is the state of the discharge activity that can lead to unforeseen failures. Hence continuous monitoring of PD enables the prevention of these unforeseen failures that result in economic losses. High voltage equipment that has been installed more than forty years ago is highly susceptible to PD since it is reaching the insulation end life. For the case of underground cables, continuous PD monitoring will help avoid unplanned outages and the need for the immediate replacement of faulty cable sections that will incur large costs. Traditionally, PD diagnostics have been carried out through offline methods, whereby the cable specimen is removed from service during the diagnostic tests. On the other hand, online PD diagnostics are preferable since the services are not disrupted. However, there are some major challenges that come with the online approach. For instance, heavy noise interference, the detection and location of PD through the interpretation of measured signals. Presented in this Thesis are presented novel contributions to the area of online PD detection for underground HV cables. The work encompasses aspects of physical data acquisition procedures and the post-processing signal processing algorithms. A new online PD data acquisition unit equipped with pre-processing and signal conditioning is presented. The system has other features that take into account the difficulties of logistics as well as issues related to the regulations and protocols of the utility. The primary aim of this developed system is to produce a PD database that will be used for research purposes. Since applied wavelets for the field of PD diagnostics have been popular amongst researchers, it was investigated further in this Thesis. Following from the data acquisition system, large data sizes required intensive processing. A new wavelet-based algorithm combined with the use of Higher Order Statistics is presented. This algorithm enables the simplification of data signals to highlight potential PD activity resulting in the reduction of manual examination of wavelet algorithms. The conventional wavelet algorithms applied in the literature generally referred to a specific approach of the wavelet implementation i. e. the decimated approach. However, it was found that the non-decimated approach has several advantages with regards to PD signature detection and PD location. The application of both approaches and their comparisons is applied to simulated data as well as online field data. Finally, the analysis of online PD data acquired from the new data acquisition system is presented. Several PD characterisation processes are applied and positive results were generated. Aspects relating to the physical environments of test site are also included. The challenges and experiences gathered in this research project are described.
