Description
The intentional delay on the phase instantaneous trip is set here in the
range 0 to 40 cycles in steps of one cycle. If 0 is selected, INST will be
INST
displayed and there will be no intentional delay. There is, however, a 1 cycle
delay which is necessary for the 565/575 relay to react to the fault
condition. If any other value is entered within the above range, the trip will
occur in this above reaction time plus the entered value. Thus, for an
INST
entered delay of 2 cycles on a 60 Hz system, the actual time to trip on
phase instantaneous is 3 × 16.6 ms = 50 ms.
Definite time characteristics can be implemented by using the phase
instantaneous trip and appropriate time delays. For example, the phase
instantaneous trip setpoint can be enabled and a delay between 0–40
cycles programmed. This effectively will simulate a Definite Time curve.
This message allows the user to select the relay or combination of relays
which the trip generated in message S 2.11 will activate.
TRIP
This setpoint allows the user to enable or disable the phase autoblock
HISET feature.
Determined after which reclosure the Phase Instantaneous Hiset Trip will
be disabled (blocked).
4
Same as PHASE HISET INST TRIP feature except any two phases must
be over the trip level to cause a trip.
ENABLED
Similar to PHASE HISET INST TRIP feature (see above).
Similar to PHASE HISET INST TRIP feature (see above).
INST
Select the desired output contact(s) to activate on a PHASE LOSET INST
TRIP .
This setpoint allows the user to enable or disable the phase autoblock
LOSET feature.
