Differential protection is a fast, selective method of protection against short-circuits which is applied in many variants for electrical machines, transformers, busbars, and electric lines. Initially this book covers the fundamentals of analog and digital differential protection. The emphasis is then placed on the different variants of differential protection and its practical application, which is illustrated by concrete examples. A textbook a...
