Non-destructive Diagnostic of High Voltage Electrical Systems

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.
