Testing the synchronizing function
This section is applicable only if the synchronizing function is included.
The voltage inputs used are:
V-Line
VA, VB or VC line 1 voltage inputs on the IED
V-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.
