6.6. COMMUNICATIONS
The test is to check that the 3 connectors in the relay allow communication with the relay. To do this it is
necessary to use a computer and a connector suitable to establish the connections between PC and relay
which are shown in figure 8.
The communication parameters which have to be set for the computer are the relay's default settings, as
follows:
Relay number:
1
Remote port baud rate: 19200
Local port baud rate:
19200
Remote stop bits:
1
Local stop bits:
1
This test is carried out at the minimum and maximum voltage that the relay will allow (
±
20% of the nominal
voltages).
6.7. RELAY SETTING
When it leaves the factory the relay has some default settings, which are the starting point for the following
tests.
Since the SMOR system has a large number of settings, an exhaustive list of all the settings necessary for
each test is not given here. The specific settings required for each test are indicated, and it can be supposed
that the other settings do not affect the test in question. For example, when testing the Overcurrent function,
the recloser and the directional control functions, etc, are disabled.
6.8. INPUTS
6.8.1. DIGITAL INPUTS
•
Apply the nominal voltage in order to each of the inputs (CC1 to CC6) and, for models with expansion
board, (CC1 to CC12).
•
Each test checks that the corresponding input is activated and that the remaining inputs (to which no
voltage is applied) are not activated. Use a PC and the GE_LOCAL software to easily check which inputs
get active.
•
Repeat this test at minimum and maximum voltage
6.8.2. SYNCHRONIZATION INPUT IRIG-B
•
Connect the output of an IRIG-B unit with decoded output to the IRIG-B input of the SMOR relay. Special
care must be taken when making the connection because the input is polarized.
•
Check that the time measured by the two units is the same.
6.9. OUTPUTS
•
Check that all the outputs are open
•
Set the Failure to open timer to the maximum. Perform an opening command and check that during the
failure to open time the Trip-1 (A11-B11) and Trip-2 (A12-B12) output contacts are closed.
