Signal of OC trip
When a user requires an alarm signal in place of the trip signal; for example, set
Alarm
for the scheme switch [
OC1-UseFor
].
Trip
is set for the scheme switch [
OC1-UseFor
] for
the normal trip operation.
2.5.6
Scheme logic
The scheme logic for both the non-directional and the directional OC1 element is illustrated in
Figure 2.5-8; Figure 2.5-9 shows grouping commands for the trip circuit (TRC). Each phase of
the OC1 element issues a pick-up when a current has been exceeded over the setting; then the
pick-up signal is transferred to into the TRC as trip signals. (For more information, see
Chapter
Relay application: Trip circuit function
)
