This paper investigates the frequency fluctuation in power system and protect the power system from its harmful effects. Therefore we design a Microcontroller Based Under/Over Frequency Relay. In this paper we use microcontroller AT89S52 for protecting the power system from the problem of frequency fluctuation. When frequency goes below or above from desired value then electromagnetic relay trip and isolate our power system from its harmful effect. Electromechanical protective relays operate by either magnetic attraction, or magnetic induction. Frequency Variation also decrease the life of the equipment and directly affect the overall production of the plant.
