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 One-and-a-half breaker arrangement.
Apply a single-phase voltage of 100% GblBaseSelLine to the U-Line and a single-
phase voltage of 100% GblBaseSelBus to the U-Bus. Verify that correct output signals
are generated.
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
18 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
18 and figure 24.
