17.1.3.3 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 SMBRREC must also be informed that the trip is
two phases by connecting the output TR2P to the input TR2P in the SMBRREC function.
17.1.3.4 Lock-out
The SMPPTRC function block is provided with possibilities to initiate lockout. The lockout can
be set to only activate the circuit breaker lockout output CLLKOUT or to both initiate the
circuit breaker lockout output and to maintain the trip signal outputs TRIP, TRL1, TRL2, TRL3,
and TR3P (latched).
If external conditions are required to initiate a circuit breaker lockout, it can be achieved by
activating input SETLKOUT. The setting
trip will not activate lockout so only initiation of the input SETLKOUT will result in lockout. This
is normally the case for overhead line protection where most faults are transient. Unsuccessful
autoreclosing and back-up zone tripping can in such cases be connected to initiate lockout by
activating the input SETLKOUT.
