Additional Functions
• Battery buffered real-time clock, which may be synchronized via a synchronization signal (e.g. DCF77, IRIG
B, GPS via satellite receiver), binary input or system interface
• Automatic time synchronization between the devices at the ends of the protected object via the protection
data transmission
• Continuous calculation and display of measured quantities on the front of the device. Indication of measured
quantities of the remote end
• Fault event memory (trip log) for the last eight network faults (faults in the power system), with real time
stamps
• Fault recording memory and and transmission of the data for fault recording for a maximum time range of
30 s, synchronized between the devices of the differential protection system.
• Switching statistics: Counting of the trip and close commands issued by the device, as well as recording of
the fault current data and accumulation of the interrupted fault currents
• Communication with central control and memory components possible via serial interfaces (depending on
the options ordered), optionally via RS232, RS485, modem connection or fibre optic cable
• Commissioning aids such as connection and direction checks as well as circuit breaker test functions
• The WEB-Monitor (installed on a PC or a laptop) widely supports the testing and commissioning procedure.
The communication topology of the differential protection and communication system, phasor diagrams of
all currents and (if applicable) voltages at both ends of the differential system are displayed as a graph
