Relay Replacement


For generations, electric power system protection has been accomplished with the use of relays – electromechanical, solid-state, and microprocessor-based. We understand the inherent strengths and weaknesses of each. We also understand that relays, like other devices, have life cycles.

RelaysNowadays, electromechanical and solid-state relays are being phased out, their strengths overshadowed by those of microprocessor-based relays. This is having a significant impact on the utilities operated by many municipal governments and universities, as well as industries.
