A review of current knowledge of electrical discharges that do not completely bridge the electrodes. Discharge detection, since 1945 and the use of new high voltage dielectrics, has grown into an indispensable tool for the evaluation of modern insulation. Topics covered include the behavior, detection and measurement of discharges, the choice of detection method and procedure, the location of discharges, and discharge detection in practice. Acidic paper. Annotation copyrighted by Book News, Inc., Portland, OR

Recent Trends in the Condition Monitoring of Transformers reflects the current interest in replacing traditional techniques used in power transformer condition monitoring with non-invasive measures such as polarization/depolarization current measurement, recovery voltage measurement, frequency domain spectroscopy and frequency response analysis. The book stresses the importance of scrutinizing the condition of transformer insulation which may fail under present day conditions of intensive use with the resulting degradation of dielectric properties causing functional failure of the transformer. The text shows the reader how to overcome the key challenges facing today’s maintenance policies, namely: The selection of appropriate techniques for dealing with each type of failure process accounting for the needs of plant owners, plant users and wider society; and Cost-efficiency and durability of effect. Many of the failure-management methods presented rely on the fact that most failures give warning when they are imminent. These potential failures give rise to identifiable physical conditions and the novel approaches described detect them so that action can be taken to avoid degeneration into full-blown functional failure. This “on-condition” maintenance means that equipment can be left in service as long as a specified set of performance standards continue to be met, avoiding the costly downtime imposed by routine and perhaps unnecessary maintenance but without risking equally expensive failure. Recent Trends in the Condition Monitoring of Transformers will be of considerable interest to both academic researchers in power systems and to engineers working in the power generation and distribution industry showing how new and more efficient methods of fault diagnosis and condition management can increase transformer efficiency and cut costs.

High Speed Pulse Technology, Volume III: Capacitor Discharge Engineering covers the production and practical application of capacitor dischargers for the generation and utilization of high speed pulsed of energy in different forms. This nine-chapter volume discusses the principles of electric current, voltage, X-rays, gamma rays, heat, beams of electrons, neutrons and ions, magnetic fields, sound, and shock waves in gases and liquids. Considerable chapters consider the applications of capacitor discharges, such as impulse hardening of steel, ultrapulse welding of precision parts, X-ray flash technology, ultrafast image converters, exploding wire shutters and light sources, electromagnetic shutters, flash photolysis, and spark tracing in aerodynamic and automotive research. The remaining chapters explore other practical aspects, including high energy electromagnetic pulse generation, plasma physics, magnet charging, magnetically driven gas and particle accelerators, acoustic echo techniques for remote atmospheric sensing, sonar, and shock waves in high pressure physics and metal forming. This book will prove useful to physicists, electrical and other engineering fields, teachers, and students who are interested in capacitor dischargers.

The report describes a method of location of discharges within the cavities of transformer insulation, using slow oscillations generated by a discharge in the transformer winding, both ends of which being connected to ground with suitable capacities in series. It follows from the theoretical considerations that the ratio of the capacities is inversely proportional to the turn ratio of the two parts of the winding on each side of the discharge point. The method was verified on two types of winding.
