It is important that a timer alarm exists in the Prepared property of each Breaker Scenario that notifies the difference between values of Scada and LoadShedding Sources on the *ShedLoadOnScenario-type Measurement. This property configured as False indicates that, if this Scenario occurs, the amount of shed load is different from the amount planned by the Load Shedding Module. This may occur due to communication errors of failures on IEDs.

If this error occurs with a high frequency for a certain Breaker, it is import to configure the *LoadSheddingBreakerAvailable-type Measurement of this device to Unavailable and notify the maintenance team about this problem. This forces the Load Shedding Module to disregard this Breaker to operate if any of the Scenarios occur.
