Testing the synchronizing function

The voltage inputs used are:
UP3LN1
UP3BB1
Testing the frequency difference
The frequency difference test should verify that operation is achieved when the frequency
difference between bus and line is less than 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
1. Apply voltages
1.1.
1.2.
2. Check that a closing pulse is submitted at a closing angle equal to calculated phase angle
value from the formula below. Modern test sets will evaluate this automatically.
