1. Connect the analog signals to the voltage inputs, in pair of two for U1 and U2. (Inputs
U3PBB1, U3PBB2, U3PLN1, U3PLN2)
2. Activate the binary signals according to the used alternative. Verify the measuring
voltage on the synchronizing check function SESRSYN. Normally it can be good to verify
synchronizing check with the same voltages and phase angles on both voltages. The
voltages should be verified to be available when selected and not available when another
input is activated so connect only one voltage transformer reference at each time.
3. Record the voltage selection tests in a matrix table showing read values and AUTOSYOK/
MANSYOK signals to document the test performed.
Testing the voltage selection for 1 1/2 CB arrangements
At test of the SESRSYN function for a 1½ CB diameter the following alternative voltage inputs
can be used for the three SESRSYN (SESRSYN 1, SESRSYN 2, SESRSYN 3) functions. These three
SESRSYN functions can either be in one, two or three different IEDs. Table
scenario when SESRSYN 1, SESRSYN 2 and SESRSYN 3 all are in the same IED. If SESRSYN 3 is in
another IED, WA1 will be considered as WA2 and LINE2 as LINE1. The voltage is selected by
activation of different inputs in the voltage selection logic as shown in table
