When a circuit breaker closing command is issued, the prepare three-phase output trip is set.
When issuing a circuit breaker closing command the
takes place during that time, the auto recloser resets to the "Ready" state and the
output resets. If the first reclosing shot fails, a three-phase trip will be initiated and three-
phase reclosing can follow, if selected.
ARMode = 1/2ph , 1-phase or 2-phase reclosing in the first shot
15.2.2.10
At single-phase or two-phase tripping, the operation is as in the example described above,
program mode
three-phase auto reclosing can follow, if selected. In the event of a three-phase trip,
high, the auto recloser will be inhibited and no auto reclosing takes place.
ARMode = 1ph+1*2ph, 1-phase or 2-phase reclosing in the first shot
15.2.2.11
At single-phase tripping, the operation is as in the above described example, program mode
1/2/3ph . The single-phase auto reclosing attempt can be followed by three-phase reclosing, if
selected. At two-phase trip, a failure of a two-phase auto reclosing attempt will inhibit the
auto recloser. No more shots are attempted. If the first trip is a three-phase 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".
15.2.2.12 ARMode = 1/2ph + 1*3ph, 1-phase, 2-phase or 3-phase reclosing in the
first shot
At single-phase or two-phase tripping, the operation is as in the example described above,
program mode
three-phase reclosing will follow, if selected. At three-phase trip, a failure of a three-phase
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-phase auto reclosing".
ARMode = 1ph + 1*2/3ph, 1-phase, 2-phase or 3-phase reclosing in the
15.2.2.13
first shot
At single-phase or two-phase tripping, the operation is as in the above described example,
program mode
three-phase reclosing will follow, if selected. At two-phase or three-phase trip a failure of a
two-phase or three-phase 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-
phase or three-phase auto reclosing".
