Figure 302: The trip logic function SMPPTRC used for single-phase tripping
application
16.1.2.3 Single-, two- or three-phase tripping
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 above, SMBRREC must also
be informed that the trip is two phases by connecting the output TR2P to the input
TR2P in the SMBRREC function.
16.1.2.4 Lock-out
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).
