synchrocheck respectively and that operation is blocked when the frequency
difference is bigger.
Test with FreqDiff = 0 mHz
Test with a frequency difference outside the set limits for manual and auto
synchrocheck respectively.
1. Apply voltages U-Line equal to 100% UBase and U-Bus equal to 100%
UBase, with a frequency difference equal to 0 mHz and a phase difference
lower than the set value.
2. Check that the AUTOSYOK and MANSYOK outputs are activated.
3. Apply voltage to the U-Line equal to 100% UBase with a frequency equal to
50 Hz and voltage U-Bus equal to 100% UBase, with a frequency outside the
set limit.
4. Check that the two outputs are not activated.
The test can be repeated with different frequency values to verify that the
function operates for values lower than the set ones. If a modern test set is
used, the frequency can be changed continuously.
Testing the reference voltage
Procedure:
1. Use the same basic test connection as in figure 12.
The UDiff between the voltage connected to U-bus and U-line should be 0%,
so that the AUTOOK and MANOK outputs are activated first.
2. Change the U-Line voltage connection to U-Line2 without changing the
setting on the local HMI.
3. Check that the two outputs are not activated.
4. The test can also be repeated by moving the U-line voltage to the U3PLN input.

Testing the energizing check

During test of the energizing check function for a single bay arrangement, these
voltage inputs are used:
U-Line UL1, UL2 or UL3 voltage input on the IED
U-Bus U-Bus voltage input on the IED
General
At test of the energizing check function for the applicable bus, arrangement shall
be done for the energizing check functions. The voltage is selected by activation of
different inputs in the voltage selection logic.
The test shall be performed according to the settings for the station. Test the
alternatives below that are applicable.
