2.17.5 Differential Protection Values
2.17.5.1 Measured values of the differential protection
The differential and restraint current values of the differential protection which are
listed in the following table can be called up at the front of the device, read out via the
operating interface using a PC with DIGSI or transferred to a control centre via the
system interface.
