NOTE: if it is wished to avoid waiting this time, which can be
very long, select OFF to stop the test: test results will be
saved anyway, and the last delay, no trip, will be displayed as
0.000.
1.11.4 Pole mounted CB test
The following is the connection schematic for this situation.
. The test is performed connecting the T1000 current output
(typically, the high current output) to the CB, that
incorporates the Recloser, and the CB position output contact
to the STOP input.
The test set measures:
. All trip delays D1, D2… of the sequence;
. All reclose delays R1, R2… of the sequence: they are
measured from the trip command leading or falling edge,
according to the selection;
. We don’t know the nominal close delays R1, R2,..: they can
be different during the test (for instance: fast reclose, slow
reclose, neutralization). In order to avoid stopping the test
before its completion, the logic is the following one:
.. If N > 1, after the first Close delay, the test set waits 99999
s for the next close command;
.. If N > 2, after the second Close delay, the test set waits for
a time equal to the former close delay, multiplied by 10.
