Function description
Tripping logic
15.1.3 Application
All trip signals from the different protection functions shall be routed through the trip logic. All
start signals and directional information can be routed through the trip logic as well. In its
simplest form, the trip logic will only link the TRIP signal to a binary output and make sure that the
pulse time is long enough.
Tripping logic SMPPTRC (94) offers three different operating modes:
• Three-pole tripping for all fault types (3p operating mode)
• Single-pole tripping for single-phase faults and three-pole tripping for multi-phase and
evolving faults (1p/3p operating mode).
• Single-pole tripping for single-pole faults, two-pole tripping for two-pole faults and three-pole
tripping for three-pole faults (1p/2p/3p operating mode).
The logic also issues a three-pole tripping command when phase selection within the operating
protection functions is not possible, or when external conditions request three-pole tripping. To

2.2.4 Added TRINN (Trip neutral) input and TRN (trip neutral) outputs. TRINALL (Trip all
phases) input is changed from TRIN. IEC 61850 mapping is made for the added output.
The block logic is corrected for the lockout functionality.
