Testing the voltage selection for double breaker
This test should verify that correct voltage is selected for the measurement in the SESRSYN function
used for a diameter in a Breaker-and-a-half arrangement. Apply a single-phase voltage of 100%
GblBaseSelLine to the V-Line and a single-phase voltage of 100% GblBaseSelBus to the V-Bus. Verify
that correct output signals are generated.
1. Connect the analog signals to the voltage inputs, in pair of two for V1 and V2. (Inputs V3PB1,
V3PB2, V3PL1, V3PL2)
2. Activate the binary signals according to the used alternative. Verify the measuring voltage on the
synchronizing check function SESRSYN (25). 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 (25) function for a breaker-and-a-half 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
