Testing the synchronizing function
This section is applicable only if the synchronizing function is included.
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
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.
