16.3.3 Switch Settings for DTT 3F Applications
Pre-Trip Timer (DTT 3F)
The Pre-Trip Timer does not allow tripping until the trip signal has been present for the time you set. You
can set this timer from 2 to 30 ms in 2 ms increments. A typical application of this timer in Direct Transfer
Trip systems is to set it for the maximum delay possible. Limitations on the critical clearing time of the
power system will have a direct impact on this setting.
The trip delay time switch settings are listed in Table 16-16.
