•
Set the fault record in the functional scope to instantaneous values record and trigger with parameter
401 WAVEFORMTRIGGER to Save w. TRIP.
•
Select the synchronization functional group and start the synchronism. The paralleling device is immedi-
ately started.
•
Read the fault record out and measure the closing time with SIGRA (see Figure 3-25). Use both cursors
and the time measurement function for that purpose. The occurrence of the 2nd voltage signals the
closed poles.
•
Set the calculated time under address 6120 as T-CB close. Round off to the next lower settable value.
Proceed for all used synchronizing functions 2 to 8 in the same way.
•
Set again the parameter 6x07 or 6x08 to the original value.

Web Tool — Measurement of the circuit breaker closing time
Test Operation with the Synchronization Function
Prerequisites
The setting values are checked again (see Section “Setting Notes” of the Synchronization Function in Chapter
2).
The circuit breaker is disconnected. The close command for the circuit breaker as well as some setpoint
commands are interrupted (disconnect the close and setpoint command). The system voltage is switched
through the measurement.
