acquisition (SCADA) function, including local and remote operation.
Voltage and current sensors shall be provided, one set for each phase, for
monitoring of both normal and fault conditions. Switches shall be provided
with visual indication of open switch contact for clearance and isolation
purposes. Switch mechanisms shall be provided with provisions for
grounding of nonenergized metal parts. The switch control unit shall be

Group Operated Load Interrupter Switches
**************************************************************************
NOTE: SF6 switches are available for nominal
voltages of 15 kV through 34.5 kV, in 600 amp
continuous and load-breaking ratings. Delete SCADA
equipment and remote telemetry when not required.
**************************************************************************
2.13.5.1
Remotely Operated (Stored-Energy Actuator)
Remotely-operated, group-operated, air insulated load interrupter switches
shall comply with ANSI C37.32 and shall be of the outdoor, three-pole, pole
or crossarm-mounted type. The electrical ratings of remotely-operated,
group-operated, gas-insulated load interrupter switches shall be in
accordance with the ratings of ANSI C37.32 and shall be of the outdoor,
three-pole, [pole-mounted] [crossarm-mounted] type. Interrupting devices
shall be [air-insulated switches] [SF6 insulated, puffer-type switches]
capable of interrupting currents equal to the switch continuous ratings
indicated.
2.13.5.2
Electric-Motor-Charged (Stored-Energy Actuator)
Switches shall utilize an electric-motor-charged, stored-energy
(spring-driven) operator to simultaneously trip all phases. A
switch-control unit shall be provided [for push-button operation from the
ground] [for push-button operation from the ground and remote switch
actuation via remote telemetry]. The switch-control unit shall be
pad-locked, tamper-resistant, NEMA ICS 6 type [3R] [4] [4X] [4X-SS]
enclosure, which is connected to the switch actuator by a shielded control
cable. Control power for closing and tripping shall be provided by a
battery mounted in the control unit enclosure. The switch-control unit
shall be provided with separate 120 volt ac circuit for the battery
charger. Power for charging the operator mechanism, may be 120 V ac power
or provided from battery power. If operating mechanism charging power is
battery, capacity shall be provided for a minimum of [_____] [four]
sequential opening and closing operations, without battery charging. The
switch-control unit shall be configured for supervisory control, and data
acquisition (SCADA) function, including local and remote operation.
Voltage and current sensors shall be provided one set for each phase, for
monitoring of both normal and fault conditions. Switches shall be provided
with visual indication of open switch contact for clearance and isolation
purposes. Switch mechanism shall be provided with provisions for grounding
of non-energized metal parts. The switch-control unit shall be provided
with a switch operations counter.
2.13.5.3
Pole-Mounted Sectionalizing Switches
Pole-mounted sectionalizing switches shall comply with IEEE C37.63.
Sectionalizers shall be coordinated with source side recloser as shown.
Ratings at 60 Hz shall be:
