Function

A frequency relay is a device used to detect frequency changes in AC power grids.The frequency of an AC power grid is an important indicator of the grid’s operating status.The frequency relay receives the frequency signal from the grid,calculates the deviation between the actual frequency and the set frequency,and then generates a control signal based on the deviation value to drive the actuator to
