In case of power-system incidents, especially in case of transmission incidents and influence of voltage-
stabilizing measures via power-electronic components (reactive-power compensation through SVC), the
magnitude and the phase angle of the voltage can change. Sensitive settings can lead to overfunction.
Therefore, it is reasonable to block the Rate of Frequency Change Protection if other protection func-
tions, for example, residual voltage or negative-sequence voltage, pick up. To do this, use the blocking
input >Block stage and connect it via CFC.
