Tripping logic (TR)
1.1
Application
The main purpose of the TR trip logic function is to serve as a single node through which all
tripping for the entire terminal is routed.
To meet the different single, double, 1 and 1/2 or other multiple circuit breaker arrangements,
one or more identical TR function blocks may be provided within a single terminal. The actual
number of these TR function blocks that may be included within any given terminal depends on
the type of terminal. Therefore, the specific circuit breaker arrangements that can be catered for,
or the number of bays of a specific arrangement that can be catered for, depends on the type of
terminal.
1.2
Functionality
The minimum duration of a trip output signal from the TR function is settable.
The TR function has a single input through which all trip output signals from the protection func-
tions within the terminal, or from external protection functions via one or more of the terminal’s
binary inputs, are routed. It has a single trip output for connection to one or more of the termi-
nal’s binary outputs, as well as to other functions within the terminal requiring this signal.
