General test connection for a 1½ breaker diameter with one-phase
voltage connected to the line side

Testing the synchronizing function
This section is applicable only if the synchronizing function is included.
The voltage inputs used are:
U-Line
UL1, UL2 or UL3 line 1 voltage inputs on the IED
U-Bus
Bus voltage input on the IED
Testing the frequency difference
The frequency difference is in the example set at 0.20 Hz on the local HMI, and the test
should verify that operation is achieved when the
FreqDiffMax
frequency difference
is lower than 0.20 Hz. The test procedure below will depend on the settings used. Input
STARTSYN must be activated during the test.
1.
Apply voltages
1.1. U-Line = 100%
GblBaseSelLine
and f-Line = 50.0 Hz
1.2. U-Bus = 100%
GblBaseSelBus
and f-Bus = 50.2Hz
2.
Check that a closing pulse is submitted at a closing angle less than 2 degrees from
phase equality. Modern test sets will evaluate this automatically.
