79 initiation is done by simply setting the desired function in the output matrix.
Figure L.18: Output Matrix
The 79 can also automatically move the follow breaker into the lead position
if the lead breaker has been out of service for an extended period of time. The
out of service indication is also used to prevent reclosing attempts to the main
or auxiliary breaker. In our example a breaker has to be opened and stay open
for a time of 120.0 seconds (TC).
The 79 can also be configured with the follow breaker switch setting. In this
example we are using the TF follow time of 5.0 seconds for the 2nd breaker
open interval. The user can use the recloser reset time of TD by selecting the
“close after recloser reset time” setting.
Figure L.19: Breaker Status
52 - Breaker Status can use any external input or ProLogic statement. The re-
closer does not have to be enabled for this logic to work. The 2 circuit breakers
cannot share the same input.
