CITY OF VERNON LIGHT AND POWER
Specification No. GS1-2003
1.0 SCOPE
This specification outlines the requirements for a three phase, group operated, 60 Hz
Resettable Fault Interrupter (RFI) switch utilizing Sulfur Hexafluoride (SF6) switches for
load interruption and SF6 vacuum breaker switches for fault interruption tested to ANSI
C37.71 or ANSI C37.60 featuring deadfront, compact, sealed, corrosion resistant
construction for vault/subsurface installations.
In comparing proposals or bids, consideration will not be confined to price only. The successful
bidder will be one whose product is judged to best serve the interests of the City of Vernon
when price, product, safety, quality and delivery are considered. The City of Vernon reserves
the right to reject any or all proposals or bids or any part thereof, and to waive any minor
technicalities from the specifications. A contract will be awarded to the bidder submitting the
lowest responsible bid meeting the requirements of this specification.
A. General
The RFI shall have two (2) switch positions and three (3) protective (fault interrupter)
positions as shown in Attachment A, Five Position S176 Gas Switch Configuration.
The RFI shall include welded flange 200Amp deepwell on the fault interrupter ways
and 600 Amp apparatus bushings on the switched positions per ANSI/IEEE 386.
(Bolted and gasketed bushings are not acceptable). Attachment A shows the one -line
diagram indicating the circuit configuration, number of switched ways, and type of
bushings required. The switched position shall be located on either end and the
resettable protective positions shall be in the middle. The switch shall be sized to fit
through a 4' x 5' foot vault opening.
The RFI shall be furnished factory filled with an electrical grade of non -toxic, non-
flammable SF6 gas, conforming to ASTM D-2472. A pressure gauge, that provides
visual status of the insulating dielectric, shall be included.
The completed unit shall be capable of withstanding internal failure without explosion
or fire and shall be capable of being mounted in any position for best cable training and
operation.
B. Switch Construction
The RFI shall use deadfront, compact, sealed construction. A corrosion -resistant
stainless steel tank shall enclose the contact system, interconnecting bus, operating
mechanisms, and bushings. The switch must be maintenance free, all welded
construction, eliminating the use of gasketed seals. T.I.G. inert gas welding with
stainless steel filler rod shall be used to eliminate pinhole leaks and corrosion.
3of10
CITY OF VERNON LIGHT AND POWER
Specification No. GS1-2003
The operating shafts must be sealed by a flexible stainless steel bellows (O-ring seals
are not acceptable).
Unless otherwise specified, cable connections, and operating accessories shall be
located so only single side access is required for operation and installation. Operating
handles shall be capable of being removed and stored or permanently attached.
Movement of the operating handles will actuate an internal spring mechanism causing
the switch/interrupter contacts to open or close and latch into position in quick make
quick break operation. The spring operator will use compression springs for long life
and will provide positive position indication.
The switch contacts and interconnecting bus shall be plated copper with Belleville
washers and locking fasteners to provide consistent pressure at bolted connections. The
contacts shall be self -aligning, wiping type, incorporating tungsten copper arcing tips to
prevent wear. The load interrupters use a puffer contact system for fast arc extinction.
A special internal absorbent shall be used for improved performance and to prevent arc
by-products.
The RFI shall incorporate vacuum technology and be capable of interrupting fault
currents up to the rated maximum. The interrupter shall use a flux shifter for tripping
and be manually resettable with no consumable parts. (i.e. fuses). As a safety
precaution, the interrupter will incorporate a trip -free mechanism to prevent the
possibility of holding the interrupter closed under a faulted condition, with no reaction
through the switch handle.
The RFI mechanism shall be a true three-phase group operated device with no
mechanical link between phases. An overcurrent condition on any phase will initiate
the interrupter to trip open all three phases. The RFI interrupter shall also act as a
three-phase, group operated loadbreak switch.
A viewing window with indication of the interrupter contact position shall be provided.
C. Trip Controls
Overcurrent sensing shall be accomplished with an electronic trip control. The controls
shall use current transformers external to the tank to sense the load currents. The
current transformers will provide power to the electronic trip control. No external
power shall be required. Per ANSI/IEEE C57.13, the current transformers shall be
relay accurate class C200 with ratios of 600:0.5A for 600 Amp positions and 200:0.5A
for 200 Amp protective positions. In order to provide immunity to system voltage
disturbances (i.e. transients) the control will not be sensitive to system voltage
conditions. The control shall be fully operable and meet the specified time -current
curves when energized. Trip controls shall be either a vacuum fluorescent type display
(VFD) selection or rotary dial.
4of10
CITY OF VERNON LIGHT AND POWER
Specification No. GS1-2003
If providing a rotary selector switch, the selector switch control shall be used for 200
amp maximum loads. There shall be 10 fuse selections ranging from 30 to 200 amps.
LED indication will be provided to show cause of the last trip simulating a S&C SM-20
"E" type fuse curve. An intermittently blinking LED shall be furnished to indicate
ready status.
The vacuum fluorescent display (VFD) shall be legible at —40°C without the need for a
heater (Operating range —40°C to +65°C). The external current transformers on the
switch will energize the display, when load current is flowing. In the event the switch
is de -energized, a 9V-lithium battery shall be included to allow operation of the display
and keypad for data gathering and parameter setting. The keypad shall be used to select
the following parameters: TCC fuse curves, TCC fuse ratings, instantaneous trip,
ground fault pick-up, ground fault delay and'protection mode. The VFD shall display
the above data as well as the cause of trip. The electronic control shall have the ability
to store up to 64 different TCC curves. Trip selection to be available in 12 positions
from 10 to 450 amps.
Instantaneous trip values shall be in multiples of 1.5 -12 times the current transformer's
primary ratings in increments of 50% of the current transformer primary rating with
values from 300A to 7200A. Ground fault trip settings shall range from 10-30% of the
current transformer primary rating in increments of 5% of the current Transformer
primary rating. Ground fault time delay shall be selectable in 10 settings from .05 to
1.0 seconds.
A RS232 port shall be provided for communication with external devices.
Status contacts for remote SCADA indication shall be provided. A manual trip push-
button for electrically tripping the interrupter shall be provided, with provision for
remote trip.
A RS232 communication port shall be provided to read real time current and fault
current.
Status contacts for remote SCADA indication shall be provided. A manual trip push-
button for electrically tripping the interrupter shall be provided, with provision for
remote trip.
