The book introduces the reader to the major components of a high voltage
system and the different insulating materials applied in particular
equipments. During a review of these materials, measurable properties
suitable for condition assessment are identified. Analyses are included
of some of the insulation fault scenarios that may occur in power
equipment. The basic facilities for carrying out tests on the internal
and external insulation structures at high and low voltages are
described. Tests and measurements according to specifications, on-site
requirements and research investigations are considered. Advances in the
application of digital techniques for detection and analyses of partial
discharges are discussed and methods in use, or under development, for
service condition monitoring are described. These include the
utilization of new sensors, the solution of online problems associated
with noise rejection and the adaptation of artificial intelligence
techniques for incipient fault diagnosis.
The subject matter of the book is suitable for final year courses in
electrical power engineering, short courses in insulation condition
assessment and postgraduate programmes. Power system engineers
associated with high voltage equipment should find the book of value in
relation to fault investigations, maintenance requirements, insulation
testing and condition monitoring.
