This section contains instructions on how to test the synchrocheck and energizing
check for single CB.
Prepare the IED for verification of settings as outlined in
verify settings".
Values of the logical signals for SESRSYN are available on the local HMI under
Main menu/Tests/Function status/Control/SESRSYN(25,SYNC)/X:SESRSYN.
The Signal Monitoring in PCM600 shows the same signals that are available on the
local HMI.
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 = On/Off/DLLB/DBLL/Both
• ManEnerg = Off
• Operation = Off/On
• Activation of the voltage selection function if applicable
The tests explained in the test procedures below describe the settings, which can be
used as references during testing before the final settings are specified. After
testing, restore the equipment to the normal or desired settings.
A secondary injection test set with the possibility to individually alter the phase
angle and amplitude of the voltage is needed. The test set must also be able to
generate different frequencies on different outputs.
The description below applies for a system with a nominal
frequency of 50 Hz but can be directly transferred to 60 Hz.
SESRSYN can be set to use different phases, phase to earth or
phase to phase. Use the set voltages instead of what is indicated below.
Figure 12 shows the general test connection principle, which can be used during
testing. This description describes the test of the version intended for one bay.
