Function description
Tripping logic
17.1.3 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 offers three different operating modes:
• Three-phase tripping for all fault types (3ph operating mode)
• Single-phase tripping for single-phase faults and three-phase tripping for multi-phase and
evolving faults (1ph/3ph operating mode).
• Single-phase tripping for single-phase faults, two-phase tripping for two-phase faults and
three-phase tripping for three-phase faults (1ph/2ph/3ph operating mode).
The logic also issues a three-phase tripping command when phase selection within the
operating protection functions is not possible, or when external conditions request three-
phase tripping.To meet the different double, 1½ breaker and other multiple circuit breaker
arrangements, multiple identical SMPPTRC function blocks are provided within the IED. In such
installation, use one instance of SMPPTRC function per circuit breaker.

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.
