2 parameters are available for the differential values voltage, frequency, and angle. Unbalanced closing ranges
can be set with this, if required.
The permissible differential values must ensure that no protection tripping or damage occurs in the system
owing to compensation processes (circulating current) and power swings after interconnection of the parts of
the power system. The settings must not be configured too closely on the other side so that necessary
closures are not blocked.
Typical differential values are selected in the default setting. Depending on the system, the settings must be
checked and adjusted, if necessary.
