. No trip command within the reclaim time: the reclose resets
its internal logic; any further fault starts a new sequence;
. Trip command within the reclaim time: the reclose issues a
new close command, possibly after a different delay; the
procedure continues until the maximum number N of close
commands has been reached, after which no further close
command is issued.
The goal of the test is to measure:
. Reclaim time TD;
. Reclose timings , that may be different during the test;
. Pre-set maximum number N of close commands;
. Verify that, if the fault occurs before TD expires, there is no
Reclose command after N faults.
The test is performed taking advantage of the features offered
by T1000 PLUS. Two test sequences are foreseen:
Normal reclose test;
Test of a pole mounted CB (that includes the reclose
device).
When you select the Reclose mode, the following screen is
opened.
Selection parameters are the following.
TD (5 s default value): it is the reclaim time; see later
on.
RECL NUM: it is the number of reclose commands that
the Recloser will issue before going to a reclose failed
status.
RECL MEASURE FROM: Tof – Ton. The reclose delay can
be defined two different ways: from the Open
