Testing Protective Relays

Diagnose Problems & Minimize Downtime

The purpose of protective relay equipment is to sense fault states and trip circuit breakers. If a fault is not corrected early, personal injuries and serious damage can occur. Since protective relay equipment plays such a vital role in electric power grid protection systems, it must be tested at regular intervals to ensure that it is operating according to preset settings.
