END-TO-END SCHEME TESTS
This section aims to check that the signalling channel is able to transmit the ON/OFF signals used in aided
schemes between the remote line ends.
Before testing, check that the channel is healthy. For example, if a power line carrier link is being used, it may not
be possible to perform the tests until the protected circuit is in service.
18.1
AIDED SCHEME 1
Aided Scheme 1 can be tested by operating output contacts to mimic the transmission of an aided channel signal.
For these tests, an engineer needs to be present at both ends of the line - at the local end to send aided signals,
and at the remote end to observe that the signals are received. A telephone link between the two commissioning
engineers is also necessary, to allow conversation.
1.
Put the IED in test mode by setting COMMISSION TESTS > Test Mode to
Blocked
.
2.
Record which contact is assigned as the Signal Send 1 output
3.
Select this output contact as the one to test and advise the engineer at the remote end that the contact is
about to be tested.
18.1.1
PREPARATION AT REMOTE END
At the remote end, the engineer must confirm the assignment of the Monitor Bits in the COMMISSION TESTS
column in the menu, to be able to see the aided channel on arrival.
Scroll down and ensure that the Monitor Bit 1 cell is set to
DDB493
and that the Monitor Bit 5 cell is set to
DDB507
. The Test Port Status cell appropriately sets or resets the bits that now represent Aided 1 Scheme Receive
(DDB493), and Aided 2 Scheme Receive (DDB507), with the rightmost bit representing Aided Channel 1. From now
on the engineer at the remote end should monitor the indication of the Test Port Status cell.
18.1.2
PERFORMING THE TEST
1.
At the local end, set the COMMISSION TESTS > Contact Test to
Apply Test
.
2.
Reset the output relay by setting COMMISSION TESTS > Contact Test to
Remove Test
.
3.
Check with the engineer at the remote end that the Aided Channel 1 signal did change state as expected.
The Test Port Status cell should have responded as in the table below
DDB No.

.
18.1.3
CHANNEL CHECK IN THE OPPOSITE DIRECTION
Repeat the aided scheme 1 test procedure, but this time to check that the channel responds correctly when keyed
from the remote end. The remote end commissioning engineer should perform the contact test, with the Monitor
Option observed at the local end.
18.2
AIDED SCHEME 2
1. If applicable, repeat the test for Aided Channel 2.
