Practical Partial Discharge Measurement on Electri cal Equipment

Accessible reference dealing with (partial discharge) PD measurement in all types of high voltage equipment using modern digital PD detectors

Practical Partial Discharge Measurement on Electrical Equipment is a timely update in the field of partial discharges (PD), covering both holistic concepts and specific modern applications in one volume. The first half of the book educates the reader on what PD is and the general principles of how it is measured and interpreted. The second half of the book is similar to a handbook, with a chapter devoted to PD measurements in each type of high voltage (HV) equipment. These chapters contain specific information of the insulation system design, causes of PD in that equipment, off-line and on-line measurement methods, interpretation methods, and relevant standards.

The work is authored by four well-known experts in the field of PD measurement who have published hundreds of technical papers on the subject and performed thousands of PD measurements on all the different types of HV equipment covered in the book. The authors have also had relationships with PD detector manufacturers, giving them key insights into test instruments and practical measurements.

Sample topics covered in the work include:

• Physics of PD, discharge phenomena (contact sparking and vibration sparking), and an introduction to PD measurement (electrical, optical, acoustic, and chemical)
• Electrical PD detection (types of sensors), RF PD detection (antenna, TEV), and PD instrumentation and display
• Off-line and on-line PD measurements, general principles of PD interpretation, and laboratory PD testing of lumped test objects
• PD in different types of HV equipment (power cables, power transformers, air insulated metal-clad switchgear, rotating machines, gas-insulated switchgear, and more)

For HV equipment OEMs, users of HV equipment, or employees of companies that provide PD testing services to clients, Practical Partial Discharge Measurement on Electrical Equipment is an essential reference to help understand general concepts about the topic and receive expert guidance during specific practical applications.

Greg C. Stone has a PhD in electrical engineering with over 45-years’ experience in performing PD testing on rotating machines and other equipment for a large electric power utility; as well as with PD equipment manufacturer Iris Power L.P., which he co-founded. He has many technical awards for his work from the IEEE, CIGRE, IEC and EPRI, and is an IEEE Fellow.

Andrea Cavallini, PhD, is with the University of Bologna, Italy where he has researched PD theory and PD test methods for 24 years, particularly for power cables, stator windings and other HV equipment. He was also a co-founder of TechImp S.r.L, a manufacturer of PD test equipment. He has over 200 papers in the PD field, including the development of the TF map method for noise and PD source identification. He is an IEEE Fellow.

Glenn Behrmann worked for over 20 years on PD measurements for GIS and rotating machines at ABB in Switzerland and its successor companies. He has been active in creating CIGRE Technical Brochures in this area, written many papers in the field, as well as helping to lead the efforts to draft IEC 62478, and revise IEC 60270 and IEEE 454. He has a BSEE from Union College in the USA.
