Reclosing Example
Automated reclosing applications can be as simple or complex as your particular station requires. All
connections between BE1-25/79TR relays, monitoring inputs, and contact sensing inputs are not shown in
our example.
Our example, Figures 1-4 illustrates a typical three transformer looped station automated reclosing
application. In this example, four BE1-25/79TR relays are used. BE1-25/79TR relay number 1 is connected
across breaker 52-1 (Line 1 potential transformer (PT) feeds the relay line input and bus D PT feeds the
relay bus input). BE1-25/79TR relay number 2 is connected in a similar manner for breaker 52-2. BE1-
25/79TR relay number 3 is connected to motor operated switch 89-4 with bus D PT feeding the line input
and bus E PT feeding the bus input. BE1-25/79TR relay number 4 is connected in a similar manner for
motor operated switch 89-5, Bus F, and Bus E. When reclosing 89-4 and 89-5, 89-4 is set to close first.
Figures 1-5 through 1-8 illustrate connections for the four BE1-25/79TR relays in our example application.
