This work examines the generation and propagation of shock waves in electric power systems. Such transients, resulting from short circuits, ground faults, and lightning strokes on lines, cables, and machines, have become the governing considerations in the design of high-voltage power systems and their components. The treatment is extended to distributed circuit elements. The distributed parameters and the time taken to propagate electromagnetic energy are given detailed examination. Typical examples have been selected so as to allow an insight into the fundamental physical behavior.
