Understanding Gang Operation When a
TripSaver II Recloser is Connected to a
Communication Gateway
The TripSaver II Communications Gateway uses SCADA
to provide unsolicited alerts, GPS time and coordinate
information, device heartbeat, and remote-mode (Auto
to R-NR) change capability to connected TripSaver II
reclosers via the DNP3 protocol. The communications
gateway also allows up to three congured TripSaver II
reclosers to be congured for local gang operation. When
a TripSaver II recloser and its associated communications
gateway have been congured for gang operation, labels
with the gang operation symbol will be supplied to be
afxed by the user to both the TripSaver II recloser and
the communications gateway cabinet. See Figure 41.
A gang operation can be initiated when one
TripSaver II recloser opens in response to an overcurrent
event, when the Local-Manual Open feature is used, and/
or when the TripSaver II recloser experiences an orientation
change, such as when it is removed from its mounting using
the Loadbuster tool. Special note should be taken when
performing maintenance on one member of a gang opera-
tion group that may change the recloser’s orientation: the
other configured TripSaver II reclosers in the gang opera-
tion group will also trip and dropout in response. Gang
operation can be disabled by connecting to the TripSaver
II Communications Gateway. For more information on the
Gang Operation feature, refer to S&C Instruction Sheet
461-509, “S&C TripSaver® II Cutout Mounted Recloser:
TripSaver® II Communications via Gateway.”
