Introduction

Abstract

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book provides a comprehensive introduction of partial discharges (PDs) – detection, identification, and localization. It also provides a far more up-to-date discussion of the topic, beginning with the physical behavior and classification of various PD types, before proceeding to discuss modeling of PD behavior. There follows a discussion of the well-known classical PD model using capacitors (and resistors), followed by discussion of the dipole model, which may bring new and interesting aspects to this field. The book then describes the measurement of PDs with decoupling, acquisition, processing, and pattern classification. It deals with electromagnetic methods and with nonelectrical methods of PD detection. The book also deals with the localization of PD effects, which is important for knowing the location of PDs.
