2.10 Tripping Output
Figure 2.10.1 shows the tripping logic. Each protection can output five tripping signals to enable
tripping for five breakers. The tripping signals are set according to the number of breakers to be
tripped and drive the high-speed tripping output relays TRIP-1 to TRIP-5.
When the scheme switch [L/O] is set to
“
ON”, the tripping output relays are latched and can only
be reset by energising the binary input for ‘Indication Reset’ operation. When the switch is set to
“
OFF”, they are reset automatically after clearing the fault.
The tripping
output relays reset 200ms after the tripping signal disappears. When [L/O] is set to
“
OFF”, the tripping circuit must be opened with the auxiliary contact of the breaker prior to reset
of the tripping relay to prevent the tripping relay from directly interrupting the tripping current of
the breaker.
