9.8.1.1 Testing the synchronizing function
M2377-21 v8
The voltage inputs used are:
UP3LN1 UL1, UL2 or UL3 line 1 voltage inputs on the IED
UP3BB1 Bus1 voltage input on the IED
Testing the frequency difference
M2377-116 v11
The frequency difference test should verify that operation is achieved when the
frequency difference between bus and line is less than set value of
FreqDiffMax
and above set value of FreqDiffMin . The test procedure below will depend on the
settings used. Input STARTSYN must be activated during the test.
FreqDiffMax = 50.2 Hz
FreqDiffMin = 50.01 Hz
tBreaker = 0.080 s
