Arc Vault™ Protection System DEH-41483 Rev. 3 Receiving, Handling and Storage

SECTION 2. RECEIVING, HANDLING AND

STORAGE

RECEIVING

Equipment packages

Every package leaving the factory is plainly marked with the case number, requisition number, and customer's order number. If the equipment has been split for shipment, the section numbers of the equipment enclosed in each shipping package are identified.

NOTICE

To avoid the loss of any parts when unpacking, the contents of each container should be carefully checked against the packing list before discarding the packing material.

The contents of each shipping package are listed on the Master Packing List. In addition, this list includes the number of the shipping crate in which miscellaneous parts needed to install and operate the equipment (such as hardware, contact lubricant, touch-up paint, breaker closing devices, etc.) are located. Normally, such devices are packed in a cardboard carton and the carton secured in an empty switchgear compartment. See Figure 2-1. If such items are packed in a switchgear section instead of a separate crate, the list will indicate the appropriate section number in which they are stored.

Figure 2-1 Packaging of loose material for shipment

1-Spare compartment 2-Carton containing loose material 3-Shipping label listing contents of carton

Inspecting for Damage

All equipment leaving the factory is carefully inspected and packed by personnel experienced in the proper handling and packing of electrical equipment. Upon receipt of any equipment, immediately perform a visual inspection to ascertain if any damage has been sustained in shipping or if there are any loose parts.

Circuit breakers and Arc Vaults may be shipped separately in individual containers with the breaker in the open position. Circuit breakers and Arc Vaults should be unpacked and visually inspected for damage or loose parts as soon as possible after they have been received.

Be sure to inspect all devices mounted or packed inside compartments of each section to see if any have been dislodged or damaged.

Filing a Claim

If any damage is evident, or indication of rough handling is visible, file a claim for damage at once with the transportation company and notify the nearest General Electric Company Sales Office immediately. Information on damaged parts, part number, case number, requisition number, etc., should accompany the claim.

HANDLING

NOTICE

It is preferable to leave the shipping skids in place under the switchgear until it reaches its final location. The equipment should be installed in its final location prior to installing the circuit breakers.

Lifting

The indoor switchgear sections are best handled by lifting with a crane as shown in Figure 2-2. Removable lifting plates are provided, as standard equipment, on the top of each switchgear section. To preserve the external appearance of the equipment, it is suggested that the lifting plates be left in place except where adjacent equipments must be bolted together, i.e. shipping splits, etc.

Utilize four equal length cables and an overhead crane, each with a minimum load rating of twice the weight of the Switchgear. Estimated weights for shipping splits appear on the Front View drawings.

DEH-41483 Rev. 3 Arc Vault™ Protection System Receiving, Handling and Storage

Example: Switchgear Section Weight = 2,000 pounds. The crane and the four lift cables must have a minimum load lifting capacity of 4,000 pounds.

Figure 2-2 Recommended lifting method

CAUTION

Gently lower the switchgear section onto the level site location. If the switchgear is roughly handled or jarred, it is possible to damage or misalign internal components.

Rollers

If crane facilities are not available, the equipment may be moved into position by means of construction rollers placed under the shipping skids. The switchgear may be raised enough for the placement of rollers by means of a fork lift or jack.

There should never be less than four rollers under the equipment unless the line-up is less than five feet long. Use one roller for each 18 inches of equipment length.

Forklifts

WARNING

The angle between the cables and the top of the equipment must be at least 45 degrees. If this is not possible because of lack of headspace, spreader bars must be used. Also, lift cables with greater load capability may be necessary, depending upon the angle between the cables and the crane hook.

Connect a cable from the crane to the four lifting plates located on the top-front and rear of the indoor switchgear. See Figure 2-2.

WARNING

Do not stand under switchgear while it is being moved. Serious injury may occur if the cables or lifting device fail.

When using a forklift to raise the line-up to position rollers underneath, proceed as follows:

1. Expand forklift tines to their maximum (widest)

extension.

2. Carefully insert tines of forklift below one side of the

switchgear line-up at the approximate center of the panel as shown in Figure 2-3.

NOTICE

Do not attempt to lift or move the equipment with a forklift positioned in the front or rear of the equipment. Equipment may tip over and get damaged.

1. Raise equipment and position one roller under the

skids close to the raised end of the line-up.

2. Carefully lower the gear until it rests on the roller as

shown in Figure 2-4.

3. Repeat the lifting process at the other end and place

the appropriate number of rollers under the skids spacing them evenly across the width of the line-up.

Arc Vault™ Protection System DEH-41483 Rev. 3 Receiving, Handling and Storage

Figure 2-3 Placing forklift tines under shipping skid

Figure 2-4 Placement of rollers under shipping skid

NOTICE

If shipping skids are removed prior to final placement of equipment, rollers may only be used to move the equipment in a direction parallel to the front.

4. While carefully pushing the switchgear to its final site

position, the rollers that are freed from the rear of the switchgear are then repositioned at the forward end. This procedure should be continued until the switchgear is in its final location. See Fig. 2-8.

5. When the switchgear is in its final position, remove all

lug bolts holding the shipping skids to the switchgear line-up.

6. Insert the tines of the forklift at one end of the line-

up, raise slightly, and remove the loose rollers.

7. Lower the end of the gear carefully to the floor.

8. Raise the other end of the line-up slightly and

remove the remaining roller at that end.

DEH-41483 Rev. 3 Arc Vault™ Protection System Receiving, Handling and Storage

Figure 2-5 Method of rolling equipment into place

Jacks

Jacks may be used in place of forklifts to raise and lower switchgear. Jacks

1. Place a jack under the front and rear corners of one

end of the line-up.

CAUTION

Do not place jacks in any other location other than the front and rear corners of the switchgear. Doing so may result in serious damage to the switchgear equipment.

2. Raise the switchgear evenly and just enough to

position a roller beneath the equipment. Gently lower the switchgear onto the roller. Repeat the procedure at the opposite end of the switchgear, raising the gear far enough to place the appropriate number of rollers under the skids, spacing then evenly across the width of the line up. Gently lower the gear onto the rollers.

4. When the switchgear is in its final position, remove all

lag bolts holding the shipping skids to the switchgear line-up.

5. Place one jack at each corner, front and rear, of the

switchgear. Carefully raise the line-up evenly and remove the rollers and the shipping skids. Evenly lower the line-up to the floor and remove the jacks.

STORAGE

Switchgear

If it is necessary to store the switchgear equipment for any length of time, the following precautions should be taken to prevent corrosion or deterioration.

1. Remove protective covering. Check thoroughly for

damage.

2. Store in a clean, dry, rodent-free location with

moderate temperature and provide protective coverings to prevent dirt, water, or other foreign substances from entering the switchgear.

3. While carefully pushing the switchgear to its final site

position, the rollers that are freed from the rear of the switchgear are then repositioned at the forward end. This procedure should be continued until the switchgear is in its final location.

Arc Vault™ Protection System DEH-41483 Rev. 3 Receiving, Handling and Storage

CAUTION

Remove all cartons, containers and any other miscellaneous packaging and packing material from inside the switchgear sections before energizing any internal heaters. To prevent fire, remove any plastic or polyethylene shrouding from the switchgear sections before energizing any internal heaters.

3. If dampness or condensation may be encountered in

the storage location, heaters must be placed inside the switchgear sections to prevent moisture damage. Approximately 250 watts of heat in each section is required. On outdoor switchgear equipment, this may be accomplished by making a temporary power supply connection to the heaters already installed in the equipment.

CAUTION

If the space heaters are to be temporarily energized from external source, it is important to remove the fuses on the secondary side of the control power transformer. This precaution is to prevent a feed back of higher voltage to other portions of the equipment through the CPT primary.

SECTION 4. EQUIPMENT INSTALLATION

GENERAL

This chapter contains complete instructions for installing General Electric Arc Vault Low-voltage equipment.

CAUTION

Personnel installing this equipment must be familiar with this instruction manual and all articles of the National Electrical Code applicable to the installation of this switchgear. In addition, all drawings, both mechanical installation and electrical, must be understood and strictly followed to prevent damage to the switchgear or equipment being protected by the switchgear.

Foundation Requirements

For optimum performance of your General Electric switchgear equipment, the foundation requirements expressed in this chapter should be strictly adhered to.

NOTICE

The foundation for the outdoor switchgear must provide proper drainage of ground and surface water accumulations away from the equipment.

The foundation must be strong enough to prevent sagging due to the weight of the switchgear structure and to withstand the shock stress caused by the opening of the breakers under fault conditions. The shock loading is approximately 1.5 times the static load.

NOTICE

Before installation work is started, it is important to review all of the drawings provided, including the General Electric equipment arrangement drawings, site installation drawings, elementary and remote connection drawings, mechanical connection drawings, and the summary of equipment list.

All expendable hardware for shipping purposes only, is painted yellow or tagged with yellow adhesive tape and may be discarded at completion of the installation phase.

Site Location

In general, the location of the switchgear equipment will have been predetermined during the specification and/or procurement of equipment phases. Indoor locations within buildings impose certain requirements which must be met so that the switchgear may operate efficiently with a minimum of maintenance.

In locating the Arc Vault equipment, adequate aisle space must be provided at the front and rear of the equipment to ensure proper ventilation of and to allow service and maintenance with the front and rear doors open. The recommended aisle space is shown on the floor plan supplied with the equipment drawings.

The switchgear equipment should be placed in an area where clean, dry air is free to circulate around and above it. Since air is taken into the equipment at the bottom of each section and exhausted at the top, a location with good airflow must be provided for efficient operation. A minimum of 30 inches of clear space above the equipment is recommended.

The foundation must be flat and level in all planes. Refer to Figure 4-1 for definition of flat and level.

The foundation should be prepared in accordance with the instructions in SECTION 4 Equipment Installation, and all embedded conduits installed and capped.

NOTICE

If rollers are to be used for movement of the equipment to its permanent installation, it is recommended that the shipping skid not be removed until the equipment is placed in position over the anchor bolts.

If a transformer is not part of the installation, and/or the equipment has been split for shipment, place the center section on the foundation first. Assemble the remaining sections outward from the center section, in each direction.

first in accordance with the instructions furnished with the transformer. All remaining sections of the switchgear should then be installed.

NOTICE

Before assembling and installing the switchgear equipment, the foundation must be absolutely level and clear of debris to prevent damage and possible mis-operation of the switchgear equipment.

Detailed Assembly and Installation Instructions (indoor)

The recommended procedure for installation of an indoor switchgear or Load Center Unit Substation is as follows:

1. POSITION THE EQUIPMENT-Position the equipment or

sections of the complete equipment in their final location.

If the switchgear equipment is part of a Load Center Unit Substation, the transformer section should be set on its pad

Arc Vault™ Protection System DEH-41483 Rev. 3 Equipment Installation

Figure 4-4 Lifting plate location

Lifting Plate

NOTICE

If the lifting plates must be reassembled on the equipment for lifting, they must be moved to locations where unused screw holes are available, generally by shifting the plate horizontally on the mounting surface one bolt-hole from its previous location. When remounting the lifting plates, torque the mounting bolts to 7-9 ft-lbs.

NOTICE

If the equipment line-up was split into shipping sections, the lifting plates on corners of adjacent sections shown in Figure 4-4 must be removed. Failure to remove these plates will interfere with mating adjacent sections and prevent installation of bus splice plates, structure tie plates, etc.

Arc Vault sections are equipped with lifting plates. These plates can be left in place when the Arc Vault section is positioned separate from the line up. Lifting plates must be removed if section will be positioned directly next to the switchgear line up.

Once the lifting plates have been removed, they may be discarded.

All mating sections of the equipment line-up (including transformer, if applicable) must be securely fastened together prior to tightening anchor bolts fastening the equipment to the mounting surface.

2. REMOVE THE SHIPPING SKIDS-The equipment is fastened

to the shipping skids with 3/8-3 lag screws through the equipment anchoring holes. See Figure 4-6.

Equipment shipping sections up to 10 feet long will be fastened to the skids with four lag screws, one in each corner. The shipping skid and lag screws are expendable material and may be disposed of at the purchaser's discretion.

3. FASTEN SECTIONS TOGETHER-After placement of the

equipment and installing the anchor bolts loosely, the various shipping sections must be rigidly fastened together. Through-bolts fasten each section of the switchgear equipment to the adjacent section. Figure 4-5 shows the location of the through-bolts.

DEH-41483 Rev. 3 Arc Vault™ Protection System Equipment Installation

Figure 4-5 Location of through-bolts

Figure 4-6 Equipment attachment to shipping skids

After completing the installation of the main bus splice bars, the joint covers may be mounted and secured by a 3/8-16 nylon bolt and polyester flat washer if the bus insulation option has been supplied with the equipment.

4. INTERCONNECT CONTROL WIRING - Interconnection of

control wiring across shipping splits is accomplished by connecting to terminal blocks located in the cross-section wiring trough on top of the equipment.

Arc Vault™ Protection System DEH-41483 Rev. 3 Equipment Installation

If terminal blocks are provided, each wire must be attached to the correct point on the terminal block, following the circuit identification number attached to each wire.

ANCHORING SWITCHGEAR EQUIPMENT INDOORS

Correct anchoring of the switchgear equipment to the foundation is very important. After completion of reassembly of the equipment at the shipping splits, the equipment anchoring procedure should be completed.

Anchoring By Anchor Bolts

1. The front of the equipment is attached to the embedded

channel sills (1), Figure 4-7, by two 3/16-inch fillet welds (2). It is recommended that two welds, each 2-1/2 inches long (min.), be used for each section to firmly tie the bottom width post (3) to the channel sill.

2. The rear of the equipment may be anchored by one of

three procedures:

• The first method is by plug welds (4), Figure 4-7, using

the anchor bolt holes in the rear sill angle (5). The plug weld should receive a minimum 1/2-inch bead around the entire circumference of the anchor bolt hole.

Indoor equipment is normally secured to its final mounting surface by anchor bolts threaded into the embedded channel sills. The bolts were loosely threaded into place before reassembling the equipment shipping splits and connecting to the close-coupled transformer, if appropriate.

The anchor bolts should now be tightened with a torque of 35-40 ft-lbs.

Anchoring By Weld

An alternate method of anchoring the equipment to its foundation is to weld the equipment to floor sills (or the floor itself if constructed of steel). Several methods, shown on Figure 4-7, are available to the purchaser for welding the equipment to the channel sills.

• A second method of securing the front and rear sill

angles (5) to the channel sill (1) is the use of two linear fillet welds (2) for each section. It is recommended that each weld be 2-1/2 inches long (min.) with a 3/16-inch fillet (min.).

• A third method for anchoring the rear of the equipment

is to remove the rear sill angle (5) from the switchgear and weld the rear bottom width post (6) to the channel sill (1). These welds (2) should, like the front welds, have a 3/16-inch (min.) fillet and each have a minimum length of 2-1/2 inches.

6. Rear width post

The four anchor bolts should be tightened with a torque of 45-55 ft-lbs.

CAUTION

If the equipment is to be subjected to operational or environmental (seismic) shock loading, the factory must be consulted for anchoring recommendations.

Control Wire Connections

For external control wiring, refer to Figure 4-3 for switchgear cable area dimensions, and connect the control wires to the switchgear section as follows.

1. When control conduits enter the switchgear from

below, they should not extend more than one inch above the floor. The control wires may be pulled through the conduits before or after the switchgear is installed.

2. Route the control wires from the conduits through the

wiring trough at the side of the cable compartment, shown in Figure 4-3. Connect the cables to the terminal blocks in accordance with the connection diagrams for the equipment.

3. If the control conduits enter from above, drill the top

cover within the available space indicated. See Figure 4-3. Control wires should be routed to the wiring trough and connected to the terminal blocks as described previously.

Power Cable Connections

Connect the main cables to the main lugs. Before any main cable connections are made, the cables should be identified to indicate their phase relationship with the equipment. Adequate electrical and mechanical clearances must be provided between conduit, cables, and bus.

Arc Vault™ Protection System DEH-41483 Rev. 3 Equipment Installation

Where the cables enter the section, they can be lashed to

Figure 4-8 Typical cable lashing

optional cable supports at the rear of the cable compartment as required.

Mechanical cable terminals are normally included with the switchgear (compression terminals are supplied when ordered) and are mounted at the ends of the breaker runbacks in the cable compartment. Carefully follow the cable manufacturer's recommendations for installation of cable.

Nylon rope – 3/8 inch (9.5 mm) diameter. Minimum of 5 wraps

Install the cables in the proper path to the terminals, using temporary lashing if required. Cut the cables to the proper length. Strip the insulation to the desired dimension, being careful not to damage any strands.

6 inches

(152 mm)

For copper cables, coat the wires with GE lubricating grease D6A15A2, insert the cables into the terminals, and tighten per torque values in Table A-2 in Appendix A.

For aluminum cables, wire brush the wire strands thoroughly. Immediately after wire brushing, coat the cable strands with a quality oxide inhibiting compound such as Penetrox A. Insert exposed wires into the terminals and tighten the set screws in accordance with values shown in the torque Table A-2 in Appendix A.

CAUTION

The torque values shown in the table are for dry threads only. Do not grease or otherwise lubricate the threads on the cable terminals as this will permit over-tightening of the screw and possible damage to the terminal or cable.

The cable supports in Figure 4-8 can be optionally ordered from the factory. The following instructions for cable lashing should be used as a guide. Run and bend the main cable in a most convenient orientation, making sure the main cable has been located directly up against any cable braces (if present) before it connects to the main cable terminals.

Using a 3/8 inch diameter continuous nylon rope or equivalent (minimum 2000 pounds tensile strength) at 6 inches from the main cable terminals, make five revolutions around the "A" and "B" phase main cables, making sure the rope does not overlap. Make five revolutions around the "B"

This should result in the oozing of compound material from between individual strands. Wipe off any excess compound.

Bolt the cable terminal connectors to the ends of the bars in the cable compartment. A non-oxidizing grease, such as GE lubricating grease D6A15A2 furnished with each equipment, should be used at these connection surfaces. The bolts should be tightened in accordance with values shown in the torque Table A-2 in Appendix A.

and "C" phase main cables. With the remaining rope, wrap around the main cable lashing between the "B" and "C" phase and the cable brace (if present) with a minimum of 5 revolutions getting as much revolutions as possible between the phases. Continue wrapping between the "A" and "B" phase around the main cable lashing and the cable brace (if present) with a minimum of 5 revolutions getting as much revolutions as possible between the phases. Securely tie off the remaining rope. Repeat this lashing at every 6-

SECTION 5. INSTALLING AND REMOVING THE

ARC VAULT DEVICE

GENERAL

Inspection and Preparation of Arc Vault

Before installing, operating, or removing an Arc Vault, check thoroughly for damaged or loose parts and for any dirt or foreign matter which may be on the Arc Vault. Be sure that a thin film of GE lubricating grease D6A15A2 is present on primary disconnects of the switchgear before installing the Arc Vault.

Arc Vault Installation

To install an Arc Vault, proceed as follows:

1. Before installing check the contact areas on each

primary disconnect bar or cluster of fingers for foreign matter that may have accumulated. Clean these areas if necessary. Be sure that a thin film of GE lubricating grease D6A15A2 covers the contact areas before putting the Arc Vault in the compartment.

2. Check to see that the Arc Vault matches its respective

compartment. The Arc Vault is assigned a part or mark number. This number is shown on the sheets of the summary, the front view drawings, and on the identification card on the Arc Vault shipping carton. The Arc Vault may also be identified using the 6 digit catalog number.

3. To locate the Arc Vault in the proper compartment,

refer to the breaker location list on the front view drawing. Find the proper Arc Vault device by the identification card on the carton.

Rejection Feature

Drawout breakers of the same type and rating are interchangeable in their equipment compartments.

Arc Vault devices will be rejected in a standard AKD-20 switchgear compartment. Drawout breakers will be rejected from a Arc Vault compartment.

INSTALLING ARC VAULT DEVICE

Pre-Installation precautions

Prior to lifting the Arc Vault to its intended compartment location, observe the following precautions.

1. Check the compartment to ensure that it is free of

foreign objects.

2. Verify that the Arc Vault is the correct type for that

compartment.

3. Ensure that the Arc Vault is discharged.

4. Apply a thin fresh coat of GE lubricating grease

D6A15A2 to the breaker’s primary disconnects.

5. Ensure that the position indicator on the cassette is in

the disconnected position and is correctly positioned for initial engagement. To do this, open the racking handle door and insert the racking handle and rotate it fully counterclockwise.

DEH-41483 Rev. 3 Arc Vault™ Protection System Testing and inspection

SECTION 6. TESTING AND INSPECTION

Table 6-1 Switchgear test voltage

GENERAL

After the equipment has been installed and all connections made, it must be tested and inspected before it is put in service. Although the equipment and devices have been tested at the factory, a final field test must be made to be sure that the equipment has been properly installed and that all connections are correct.

WARNING

Risk of shock. The equipment must be completely deenergized while the tests are in progress. Failure to do so may result in death or serious injury.

Directions for testing relays, instruments, and meters are given in the instruction book furnished for each device. The proper settings of the protective relays and Arc Vault trip units are normally determined from a complete power system coordination study performed by the purchaser or their consultant; therefore, the settings of these devices must be made by the purchaser. When the equipment is shipped from the factory, the time dial of all inverse-time induction disc relays (i.e., IFC types) is set to zero to prevent contact bounce during transportation.

Switchgear Voltage Rating

600V 480V

KEY INTERLOCKS

After initial installation of the switchgear equipment, all necessary interlock keys should be inserted into the appropriate locks and all spare keys should be stored in a location in accordance with the owner's established procedures.

ANSI Test Voltage, AC RMS

2200V 1960V

Field Test Voltage, AC RMS

1650V 1470V

CAUTION

Refer to the key interlock schematic included in the summary furnished with the equipment to determine the sequence of operation and the correct number of operating keys required. This precaution is necessary since the improper use of spare keys will defeat the interlocking scheme.

NOTICE

The trip setting adjustments of the relay for each Arc Vault may be at any setting when shipped from the factory and must be correctly set prior to energizing the equipment.

General instructions for setting the relays are given in Arc Vault Relay Controller page 33.

The extent of the tests on the equipment as a whole will depend on the type and function of the equipment. Tests which should be performed, however, include Arc Vault operation, and switchgear meggering, phasing, and grounding checks.

If local codes demand a high potential test, or the purchaser wishes to make these tests, the voltage should not exceed 75 percent of the IEEE factory test voltage.

For the power circuit, the IEEE factory test voltage is two times switchgear rating plus 1,000 volts.

CAUTION

Potential and control power transformers must be disconnected during high-voltage testing.

Test

The compartment housing the Arc Vault has a TEST position in which the primary contacts are disconnected while the secondary contacts are still engaged. This TEST position permits complete testing of the electrical control circuit without energizing the primary power circuit. When the Arc

device is first put into service, its control circuit must

Vault be thoroughly tested while in this position to make sure that all closing and tripping circuits are complete and functioning properly.

The TEST position is not suitable for inspection and maintenance of the Arc Vault be used only for testing Arc Vault

Once in the TEST position the device can be tested by pressing the “Press to Charge” button. The indicators directly above the button will show the state of the device.

Red light - indicated not charged

Yellow light – indicates charging or discharging this may take a few seconds

Arc Vault™ Protection System DEH-41483 Rev. 3 Testing and inspection

Reset the pop out indicator by depressing the yellow indicator. This procedure may be repeated if desired.

ARC VAULT RELAY

The calibration of the Arc Vault relay trip system is comprised of the following components.

Discharged

Charged

1. Manually exercise all circuit breakers that the, Arc Vault

relay will be controlling, and other operating mechanisms to make certain they are properly aligned and operate freely.

2. Conduct an electrical insulation resistance test to make

sure the switchgear is free from short circuits and grounds. This should be done both phase-to-ground and phase-to-phase with the switches or circuit breakers both opened and closed. The Arc Vault Device shall be in the discharged state. This test should be performed with a 1000 volt meggar. Disconnect all control circuits before checking resistance.

3. Upstream breaker must be tested to verify it is

functional and can clear the fault in less than 5 cycles.

WARNING

Upstream breaker is responsible for interrupting arcing event. Make sure breaker is functional upon trip signal. Failure to do so may result in death or serious injury.

3A. Verify CTs are properly connected.

• Relay

• Current transformers Class C50 or better 5000:5A

• Shunt trip on the tripable device

WARNING

Correct current transformer class and rating is critical to proper system function.

All control components, except the CT’s and the Shunt trip are integrally mounted in the Arc Vault Protection System stack in drawout construction. The Relay is automatically connected to the device via a drawout secondary disconnect block.

WARNING

Never disengage the relay without shorting the Current transformers properly. This will open-circuit the current sensors, allowing dangerous and damaging voltages to develop.

4. Check any electrical relays, meters, or instrumentation

to determine that connections are made properly and the devices function properly.

5. Electrically exercise all electrically operated circuit

breakers, and other mechanisms (but not under load), to determine that the devices operate properly. An auxiliary source of control power may be necessary to provide power to the electrical operators.

6. Make certain that field wiring is clear of live bus and,

where necessary, physically secured to withstand the effects of fault currents.

7. Check to determine that all grounding connections are

made properly.

8. Remove all debris, scrap wire, etc., from the switchgear

interior before closing the enclosure.

9. Install covers, close doors, and make certain that no

wires are pinched and that all enclosure parts are properly aligned and tightened.

FINAL STEPS TO BE TAKEN BEFORE ENERGIZING EQUIPMENT

The following steps should be taken before energizing the equipment.

DEH-41483 Rev. 3 Arc Vault™ Protection System Operation

SECTION 7. OPERATION

ARC VAULT DEVICE OPERATION

Included below are abbreviated operating instructions for Arc Vault. Before activation of the Arc Vault or operation of the switchgear equipment, thoroughly read, and be familiar with this Arc Vault manual.

All Arc Vault devices are manually operated. They are equipped with an integral charging push button marked “Push to Charge” on the front of the escutcheon.

The charge indicator will show CHARGED by illuminating the green LED when the charge button is pressed to the “in” position.

A mechanically operated DISCHARGE button mounted on the device escutcheon discharges the unit when pressed to the “in” position.

ARC VAULT DRAWOUT OPERATION

Arc Vault Positions

Refer to Figure 7-1. The drawout operation features four positions:

1. CONNECTED - In the CONNECTED position, the primary

and secondary disconnects are fully engaged. The device must be discharged before it can be racked out of this position.

2. TEST - When in the TEST position, the primary contacts

are disconnected, but the secondary contacts remain engaged. This allows test firing the device without creating a fault on the primary circuit.

3. DISCONNECTED - In the DISCONNECTED position,

neither primary nor secondary contacts are made. The Device may be racked between these three positions with the compartment door closed and latched.

4. WITHDRAWN - With the door open, the device can be

rolled out manually from the DISCONNECTED to the WITHDRAWN position. Here, the device is completely out of its compartment, ready for removal.

Figure 7-1 Arc Vault gear shown in disconnected position

Drawout Operation

The device is supported on the drawout rails mounted on the side walls of the cassette. The Arc Vault device has two wheels on each side of the device frame that rest on each drawout rail.

Motion is provided by a mechanism mounted on the bottom of the cassette. This mechanism drives racking cams which engage pins anchored to each side of the device.

The cams are driven by a removable racking handle or remote racker which engages the mechanism. The handle is inserted through an opening in the cassette escutcheon below the device.

Turning the handle in a clockwise direction drives the device into the compartment. As the device disconnect fingers engage the stab tips, a high force will be felt. Turn the racking handle and verify position by using the alignment markers on the side of the device or indicator barrel.

The indicator barrel should clearly show CONNECTED.

The position of the device is given by the position indicator in the cassette escutcheon as it moves through the door cutout. Racking position can also be verified by using the alignment markers on the side of the device.

SECTION 11. MAINTAINING THE

SWITCHGEAR

MAINTENANCE REQUIREMENTS

A periodic maintenance schedule must be established to obtain the best service from the switchgear. An annual check of the switchgear devices and all connections should be made as a minimum requirement. Equipment subject to highly repetitive operation may require more frequent maintenance.

A permanent record of all maintenance work should be kept. The record should include a list of periodic checks and tests made, the date they were made, the condition of the equipment, and any repairs or adjustments that were performed. Maintenance employees must follow all recognized safety practices, such as those contained in NFPA 70B: Electrical Equipment Maintenance, and NFPA 70E: Standard for Electrical Safety in the Workplace and in company or other safety regulations.

WARNING

Solid insulation surrounding an energized conductor and power apparatus must never be relied upon to provide protection to personnel.

For specific information regarding the maintenance of devices, such as circuit breakers, relays, meters, etc., refer to the separate instruction book furnished for each device.

DEVICE AND INSTRUMENT COMPARTMENTS

Periodic inspection of the Arc Vault is recommended at least once a year. This is typical of a LV breaker. More frequent inspections are recommended where severe load conditions, dust, moisture or other unfavorable conditions exist, or if the vital nature of the load warrants it. Always replace the device after a short-circuit current has been interrupted.

MAINTENANCE OF ARC VAULT DEVICE

Arc Vault Device: Test for Proper Operation

Test and inspect all Arc Vaults for proper operation as follows.

1. Periodic testing of capacitor function is recommended.

This maintenance will verify the Arc Vaults readiness status and alert maintenance employees if service is required. This capacitor performance check can be performed while in the TEST position.

2. Perform capacitor discharge test. See Test on page 25.

3. GE recommends that you replace the Electrical

Contoller module GAVCR1 7 years after initial installation or if capacitor status light (Charged Light) fails to illuminate.

4. GE recommends that you replace the Arc Vault Relay

GAVRR1,2,3 15 years after initial installation.

WARNING

Primary equipment must be completely de-energized while tests on control circuits, etc. are being conducted. Be sure that all areas of feedback from secondary circuits, as well as outside sources, are disconnected.

5. Remove the breakers from their compartments to a

clean maintenance area. Close compartment door and cover the breaker cutout to prevent access to live parts.

WARNING

De-energize equipment completely before doing maintenance work on any devices, connections, bus work, breaker or feeder cable compartments. This includes de-energizing any connections to outside primary or secondary sources, such as transformers, tie lines, etc.

Checks After Switchgear Is De-energized

At the time of inspection, the following checks should be made after the switchgear has been de-energized. Control power is required for these tests.

1. Move device from connect to test position.

2. Manually operate the Arc Vault

checking for obstructions or excessive friction. Manual firing of the Arc Vault may be performed by the following two steps:

a. Depress the “Push to Charge” button for the Arc Vault. The charge indicator green LED will show CHARGED.

b. Depress the “Push to Discharge” button on the front of the device. The charge indicator red LED will show DISCHARGED.
