When a circuit breaker closing command is issued, the prepare three-pole output trip is
set. When issuing a circuit breaker closing command the
tReclaim
timer is started. If no
tripping takes place during that time, the auto recloser resets to the “Ready” state and
the
ACTIVE
output resets. If the first reclosing shot fails, a three-phase trip will be
initiated and three-phase reclosing can follow, if selected.
14.2.2.10
ARMode = 1/2ph, 1-phase or 2-phase reclosing in the first shot
M12391-136 v5
At single-pole or two-pole tripping, the operation is as in the example described above,
program mode
1/2/3ph
. If the first reclosing shot fails, a three-pole trip will be issued
and three-pole auto reclosing can follow, if selected. In the event of a three-pole trip,
TR3P
input high, the auto recloser will be inhibited and no auto reclosing takes place.
14.2.2.11
ARMode = 1ph+1*2ph, 1-phase or 2-phase reclosing in the first shot
M12391-139 v5
At single-pole tripping, the operation is as in the above described example, program
mode
1/2/3ph
. The single-pole auto reclosing attempt can be followed by three-pole
reclosing, if selected. At two-pole trip, a failure of a two-pole auto reclosing attempt
will inhibit the auto recloser. No more shots are attempted. If the first trip is a three-
pole trip, the auto-reclosing will be inhibited. No more shots are attempted. The
expression “1*2ph” should be understood as “Only one shot at two-phase auto
reclosing”.
14.2.2.12
ARMode = 1/2ph + 1*3ph, 1-phase, 2-phase or 3-phase reclosing in the
first shot
GUID-9C2FB801-F324-465E-8FD2-715A9C3D0BD8 v2
At single-pole or two-pole tripping, the operation is as in the example described above,
program mode
1/2/3ph
. If the first reclosing shot fails, a three-pole trip will be issued
and three-pole reclosing will follow, if selected. At three-pole trip, a failure of a three-
pole auto reclosing attempt will inhibit the auto recloser. No more shots are attempted.
The expression “1*3ph” should be understood as “Only one shot at three-pole auto
reclosing”.
14.2.2.13
ARMode = 1ph + 1*2/3ph, 1-phase, 2-phase or 3-phase reclosing in the
first shot
M12391-146 v5
At single-pole or two-pole tripping, the operation is as in the above described example,
program mode
1/2/3ph
. If the first reclosing shot fails, a three-pole trip will be issued
and three-pole reclosing will follow, if selected. At two-pole or three-pole trip a failure
of a two-pole or three-pole auto reclosing attempt will inhibit the auto recloser. No
more shots are attempted. The expression “1*2/3ph” should be understood as “Only
one shot at two-pole or three-pole auto reclosing”.
