The main physical processes and phenomena in pulsed electric breakdown of liquids are described. The nature of charge carriers, mechanisms of formation and evolution of the gas phase, and their role in charge ignition (initiation) and development are considered. Spatiotemporal laws of propagation and parameters of charge channels are described. The basic mechanisms of liquid breakdowns and boundary conditions of their initiation are formulated. The monograph will be useful to experts in high-voltage pulsed technology, physics of dielectrics, and electrical insulation as well as to students of the corresponding speciality.
