This book introduces the major components of high voltage systems and the insulating materials used in specific equipment. It identifies measurable properties of these materials that are suitable for condition assessment and analyses various insulation fault scenarios that can occur in power equipment. The text also describes the fundamental facilities for testing internal and external insulation structures at high and low voltages.
Tests and measurements are considered in the context of specifications, on-site requirements, and research investigations. Advances in digital techniques for detecting and analyzing partial discharges are discussed, along with methods currently in use or under development for service condition monitoring. These include new sensor technologies, solutions for online noise rejection, and the application of artificial intelligence techniques for early fault diagnosis.
The book is suitable for final-year electrical power engineering courses, short courses in insulation condition assessment, and postgraduate programs. Power system engineers working with high voltage equipment will find it valuable for fault investigations, maintenance planning, insulation testing, and condition monitoring.
