ABB Relion 670 series - Armode = 1 Ph+1*2 Ph, 1-Phase or 2-Phase Reclosing in the First Shot

15.2.2.10 ARMode = 1/2ph , 1-phase or 2-phase reclosing in the first shot
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.
15.2.2.11
ARMode = 1ph+1*2ph, 1-phase or 2-phase reclosing in the first shot
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”.
15.2.2.12 ARMode = 1/2ph + 1*3ph, 1-phase, 2-phase or 3-phase reclosing in the
first shot
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”.
15.2.2.13
ARMode = 1ph + 1*2/3ph, 1-phase, 2-phase or 3-phase reclosing in the
first shot
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”.
