Open Interval and O/C Sequence Time
If the reclosing sequence consists of just the
Initial Trip
operation (i.e., single shot
to lockout), the reset time does not need to be entered. If there are two or more trip
operations, the open interval must be entered between adjacent trip operations in addition
to the reset time. On the screen, the setting field for the
Open Interval
setting is located
between two adjacent trip operations; the field for the
O/C Sequence Time
setting is
always located at the end of all trip operations. See Figure 66.
Figure 66. The Open Interval and O/C Sequence Time setting field locations.
Open Interval following Initial Trip, Test 1, or Test 2.
Specify interrupter open
time (in seconds) before it recloses after the initial
Trip
operation, after Test 1, or after
Test 2, as applicable (minimum value = 0.5; maximum value = 5 [or 30 for extended open
interval-capable reclosers]). See Figure 66.
O/C Sequence Time.
Specify the reset time for the test sequence, in seconds (minimum
value = 0.5; maximum value = 1000). If a TripSaver II recloser remains closed upon
completion of an action in the test sequence—and the overcurrent element has not picked
up and started timing again within this setting—the test sequence counter will reset
and the TCC curve will reset to its setting defined in the
Trip
operation. See Figure 66.
Note:
An active
O/C Sequence Time
timer will not expire after a TripSaver II recloser
loses power. It will continue counting down until the defined duration has been reached.
