Power system protection has a more than a century history of remarkable developments. In the early days, electro-mechanical systems were used for protection. Ingenious developments created remarkable electromechanical systems that can distinguish faulty conditions, evaluate the approximate location of faults, determine loss of excitation in generators, to mention only a few. In the 60s, the practical utilization of solid state technology initiated the implementation of solid state relays that could perform the same functions.  More
