3.2 Recommendations for
output signals
Auto-reclosing - Single- and/or
three-phase
AR01-TRSOTF
is connected to the internal line protection, distance protection, trip
switch-onto-fault.
AR01-TPTRIP
is connected to the internal function TRIP, or to a binary input. The protec-
tion functions that give a three-phase trip are supposed to be routed via that
function.
AR01-READY
can be connected to the Zone extension of a line protection. It can also be
used for indication, if required.
AR01-SP1
single-phase reclosing in progress is used to temporarily block an Earth-
fault protection and/or a Pole disagreement function during the single-
phase open interval.
AR01-CLOSECB
connect to a binary output relay for breaker closing command.
AR01-P3PH
prepare three-phase trip: Connect to TRIP-PTPTRIP.
AR01-P1PH
permit single-phase trip: Can be connected to a binary output for connec-
tion to external protection or trip relays. In case of total loss of auxiliary
voltage, the output relay drops, and does not allow single-phase tripping.
If needed to invert the signal, it can be made by a break contact of the out-
put relay.
The other output signals can be connected for indication, disturbance
recording, and so on, as required.
