17.1.2.3 Single-, two- or three-phase tripping
M14828-15 v5
The single-/two-/three-phase tripping mode provides single-phase tripping for
single-phase faults, two-phase tripping for two-phase faults and three-phase
tripping for three-phase faults. The operating mode is always used together with an
autoreclosing scheme with setting
ARMode = 1/2/3 ph or ARMode = 1/2 ph .
The functionality is very similar to the single-phase scheme described above.
However, in addition to the connections for single phase SMBRREC must also be
informed that the trip is two phases by connecting the output TR2P to the input
TR2P in the SMBRREC function.
17.1.2.4 Lock-out
M14828-18 v6
The SMPPTRC function block is provided with possibilities to initiate lock-out.
The lock-out can be set to only activate the block closing output CLLKOUT or
initiate the block closing output and also maintain the trip signal output TR3P
(latched trip).
