1. Connect the signals above to binary inputs and binary outputs.
2. Connect the voltage inputs to the analog inputs used for each bus or line depending of the
type of busbar arrangement and verify that correct output signals are generated.
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
GblBaseSelLine to the V-Line and a single-phase voltage of 100% GblBaseSelBus to the V-
100%
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
describes the 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
figure 53.
