Testing functionality by secondary injection
Ud>MainBlock or Ud>PilotAlarm. MAINFUF or PILOTFUF signals are
activated without any time delay.
3. Set normal conditions as mentioned in step 1. MAINFUF or PILOTFUF
signals should reset.
4. Set SealIn to On, UD>MainBlock to 20% of UBase and USealIn to 70% of
UBase.
5. Apply three-phase voltages with the value slightly below USealIn level.
6. Decrease one of the three-phase voltages on main fuse group. The voltage
change must be greater than the set value for Ud>MainBlock. MAINFUF
signal is activated.
7. After more than 5 seconds increase the measured voltage back to the value
slightly below USealIn level. MAINFUF signal should not reset.
8. Slowly increase measured voltage to the value slightly above USealIn until
MAINFUF signal resets.
9. Record the measured voltage and compare with the set value USealIn.

Completing the test

Continue to test another function or end the test by changing the TESTMODE
setting to Off. Restore connections and settings to their original values, if they were
changed for testing purposes.

Control

Synchrocheck, energizing check, and synchronizing
SESRSYN
This section contains instructions on how to test the synchrocheck, energizing
check, and synchronizing function SESRSYN for single, double and 1½ breaker
arrangements.
Prepare the IED for verification of settings outlined in Section
to verify settings".
At commissioning and periodical checks, the functions shall be tested with the used
settings. To test a specific function, it might be necessary to change some setting
parameters, for example:
• AutoEnerg = Off/DLLB/DBLL/Both
• ManEnerg = Off
• Operation = Off/On
• Activation of the voltage selection function if applicable
