"… Elmore has been nationally recognized for decades as an authority in relay technology. … [T]he language is clear, the math isn't daunting, and the many diagrams are a great aid to understanding. Elmore's book will continue to be a bible for the relay engineer, as the earlier Westinghouse publication was for so many years."
