This book describes the methods of signal processing used in the non-destructive diagnostics of mechanical and electrical properties of high-voltage electrical machines. Traditional and less traditional methods are given, which allow measuring the mechanical and electrical properties of these machines in order to determine their technical condition, including a description of their measurement methods. Separate chapters are devoted to the causes and methods of measuring and evaluating partial discharges arising in the insulation systems of high-voltage electrical machines. The following chapters provide an overview of the test methods used in the non-disassembly diagnostics of high-voltage transformers, rotary machines, high-voltage cables, insulators, surge arresters and circuit breakers.
The book is intended for students of technical universities and experts in the field of non- destructive diagnostics of high-voltage electrical machines.
The book was reviewed by Ing. Jiří Brázdil, Ph.D. MBA, Head of the HV laboratory of ORGREZ in the Czech Republic.

In 1971, Josef Vedral graduated from the Czech Technical University in Prague, Faculty of Electrical Engineering in the field of measuring technology. In 1976 he completed his doctoral studies at the Department of Measurement of the Czech Technical University in Prague in the field of measuring instrumentation. In recent years, he has been engaged in condition monitoring of HV electric machines. Between 2012 and 2020 he was the head of two projects of the Technology Agency of the Czech Republic projects "Intelligent measuring diagnostic system for estimating the operating condition of high-voltage electric rotary and non-rotating machines" and the related project "Compact diagnostic system for monitoring the condition of high-voltage electric machines using DC and low-frequency alternating test voltage". He is the author of 82 scientific articles in international journals, 12 Czech patents, 12 university textbooks in Czech and 2 textbooks in English.
