Setting guidelines

Remember always that there are two possible ways to place the IED in the
state. If, the IED is set to normal operation (
being in the test mode, the input signal IED_TEST on the TESTMODE function block is
activated in the configuration.
Forcing of binary input and output signals is only possible when the IED is in IED test mode.

Time synchronization

22.13.1

Application

Use time synchronization to achieve a common time base for the IEDs in a protection and
control system. This makes it possible to compare events and disturbance data between all
IEDs in the system. If a global common source (i.e. GPS) is used in different substations for the
time synchronization, also comparisons and analysis between recordings made at different
locations can be easily performed and a more accurate view of the actual sequence of events
can be obtained.
Time-tagging of internal events and disturbances are an excellent help when evaluating faults.
Without time synchronization, only the events within one IED can be compared with each
other. With time synchronization, events and disturbances within the whole network, can be
compared and evaluated.
In the IED, the internal time can be synchronized from the following sources:
• BIN (Binary Minute Pulse)
• DNP
• GPS
• IEC103
• SNTP
• IRIG-B
• SPA
• LON
• PPS
