High Voltage Engineering

Inspired by a new revival of worldwide interest in extra‑high‑voltage (EHV) and ultra‑high‑voltage (UHV) transmission High Voltage Engineering Second Edition merges the latest research with the extensive experience of the best in the field to deliver a comprehensive treatment of electrical insulation systems for the next generation of utility engineers and electric power professionals. This book offers extensive coverage of the physical basis of high voltage engineering from insulation stress and strength to lightning attachment and protection and beyond. Presenting information critical to the design selection testing maintenance and operation of a myriad of high‑voltage power equipment this must‑have text: Discusses power system overvoltages electric field calculation and statistical analysis of ionization and breakdown phenomena essential for proper planning and interpretation of high‑voltage tests Considers the breakdown of gases (SF6) liquids (insulating oil) solids and composite materials as well as the breakdown characteristics of long air gaps Describes insulation systems currently used in high‑voltage engineering including air insulation and insulators in overhead power transmission lines gas‑insulated substation (GIS) and cables oil‑paper insulation in power transformers paper‑oil insulation in high‑voltage cables and polymer insulation in cables Examines contemporary practices in insulation coordination in association with the International Electrotechnical Commission (IEC) definition and the latest standards Explores high‑voltage testing and measuring techniques from the generation of test voltages to digital measuring methods With an emphasis on handling practical situations encountered in the operation of high‑voltage power equipment High Voltage Engineering Second Edition provides readers with a detailed real‑world understanding of electrical insulation systems including the various factors affecting—and the actual means of evaluating—insulation performance and their application in the establishment of technical specifications.
