5 — Recloser Operation

Overview

The VERSA-TECH® Recloser is a unique and patented approach to recloser design. The interrupter, drive mechanism, control, and housing are raised to the system potential. The entire assembly is then insulated from ground using a standard polymer post insulator. This approach allows a compact simpliﬁed design and also eliminates the potential for an insulation breakdown failure.

The fault interruption occurs in the recloser’s vacuum interrupter. This vacuum interrupter has state of the art contacts utilizing axial magnetic ﬁelds to interrupt in diffuse mode for maximum interrupter life. The vacuum interrupter is supported by an insulating support housing with bonded epoxy composite formulation over-molding for maximum weather resistance.

The drive for the vacuum interrupter is provided by a mechanism with a magnetic actuator. The actuator has a rare-earth neodymium magnet, which provides the latching and holding force for the vacuum interrupter in the closed position. A spring provides the pressure to hold the vacuum interrupter in the open position. Together the rare-earth magnet and the spring arrangement allow the mechanism to be stable in the open or closed position without the need for external power. To open the vacuum interrupter a coil on the magnetic actuator is pulsed in one direction. To close the same coil is pulsed in the other direction. Energy to open and close the recloser is provided by a set of capacitors.

The control for the recloser is provided by a microprocessor based electronic circuit. The control is designed to allow complete ﬂexibility and user choice of minimum trip, time-current curves and sequencing parameters. User access to all parameters is provided through an RS-232 serial connection. Current sensing for the control occurs through a 1000:1 current transformer.

No external transformer power for the recloser is required. Power for the control and the mechanism is converted from fault or load current using two power current transformers. The open and close capacitors needed to drive the recloser are charged by the load or fault current through the power current transformers. Using this approach the recloser will continue to open and close as necessary without the need for external power or even the hot-stick replaceable lithium battery pack. The lithium battery

pack provides power to the real time clock, beacon, the remote radio when current is less than 10A when the Non-Reclose handle is engaged (See Recloser Operation Section) and after lockout or manual open.

Automatic Operation

The VERSA-TECH® Recloser, when in the closed position, operates automatically per the programmed user settings.

Operations Counter*

Refer to Figure 5-1 for Counter location. Operations counter is an electromechanical counter, which counts open operations both manual and automatic initiated by the control.

*Applicable to VTI only. External operations counter is not present on the VTLT.

Non-Reclosing Lever/Hot Line Tag

Refer to Figure 5-1 for the location of the Non-Reclosing Lever (red lever). The handle is shown in the normal or UP position. In this position, the recloser will follow the automatic sequence it has been programmed for.

Legacy Versa-Tech I Reclosers (manufactured July 2011 and

earlier):

The Versa-Tech Programmer User Interface (UI) allows the programming of the NonReclosing (NR) lever to a single functionality mode only (Non-Reclose Mode OR Hot Line Tag mode). If the NR Mode Only is selected when the red lever is rotated 90 degrees clockwise to the down position, the recloser will trip using TCC1 and lockout on any current above minimum trip. If the Hot Line Tag (HLT) Mode Only is selected when the red lever is rotated 90 degrees clockwise to the down position, the recloser will trip instantaneously and lockout on any current above minimum trip.

Versa-Tech Reclosers manufactured after July 2011 (Versa-Tech I and Versa-Tech LT):

The Versa-Tech Programmer User Interface (UI) allows the programming of the NonReclosing (NR) lever to a dual functionality mode (Non-Reclose/Hot Line Tag) or a single functionality mode (Hot Line Tag Only). When the "NonReclose/Hot Line Tag" option is selected, the recloser will be in a Non-Reclose mode

when the red lever is rotated to the down position one time. In the NR mode, the recloser will trip using TCC1 and lockout on any current above minimum trip. If the red lever is rotated to the down position twice within 30 seconds, the recloser will be placed in Hot Line Tag mode. The Hot Line Tag Mode is an instantaneous trip mode. When the "Hot Line Tag Only" option is selected, the recloser will always be in Hot Line Tag mode when the red lever is placed in the down position.

Note for Versa-Tech I Reclosers with Firmware 4.xx: For Versa-Tech I Reclosers

with ﬁrmware version 4.xx, whenthe recloser locks out on Hot Line Tag, the solenoid can be closed only after the Hot Line Tag mode is disabled. This is accomplished by ﬁrst rotating the red lever back to its original position (UP) and then by pushing the Manual Handle (yellow handle) back to its UP position. If the Manual Handle is UP prior to putting the red lever to the UP position, the Manual Handle must be pulled DOWN and then pushed to the UP position in order for the solenoid to close.

All Versa-Tech I and Versa-Tech LT Reclosers: Hot Line Tag is an instantaneous

trip mode. As long as the capacitors are fully charged, the Versa-Tech will trip in 1/2 cycle or 8ms while in HLT. Hot Line Tag takes precedence over Cold Load Time and Non-Reclose mode. Cold Load Time takes precedence over Non-Reclose Mode. The red lever is also used to turn on the remote radio (Digi/XBee, SiFLEX, or WiFi) when line current goes below 10A. To turn on the remote radio, pull the red lever DOWN and then push it UP within 30 seconds. the radio will then automatically shut OFF after 10 minutes of communications inactivity to minimize battery drain. If the red lever is left in the DOWN position, the radio will be powered for 60 minutes before automatically shutting OFF.

5 — Recloser Operation

Manual Operating Handle

Refer to Figure 5-1 for Manual Operating Handle location. The manual operating handle is designed to allow manual operation of the recloser with a hotstick. If the manual handle operating handle is rotated 90 degrees counter-clockwise to the down (open) position the recloser will open and interrupt the distribution circuit. Pulling the manual handle down anytime will manually pull open the mechanism and the vacuum interrupter opening the recloser.

Closing the recloser after a manual open or automatic lockout can be done by moving the manual operating handle clockwise 90 degrees to the up (closed) position. This will activate the electronic control, which will initiate the close sequence. Before the recloser is closed the close capacitor is charged to the required level from the lithium batteries. When it reaches the necessary charge level, the magnetic actuator closes the recloser. This process from movement of the handle until the recloser closes may take a few seconds.

Lockout Beacon

Refer to Figure 5-1 for Beacon location. The Lockout Beacon is a unique feature which is designed to aid the utility lineman in identifying a locked out recloser. This high intensity sunlight visible amber LED will ﬂash once every 3 seconds when the recloser has sequenced to lockout. The lithium batteries provide the power for the ﬂashing beacon.

Versa-Tech I Reclosers with FW 3.xx and Versa-Tech LT Reclosers:

The beacon will continue to ﬂash every 3 seconds until the lineman closes the recloser or 1 hour has passed. After 1 hour, the ﬂashing beacon will automatically shut OFF. The beacon is also utilized when the recloser is manually opened. When manually opened, the beacon will continue to ﬂash until the recloser is closed or 60 seconds has passed.

Versa-Tech I Reclosers with FW 4.xx:

The beacon will continue to ﬂash every 3 seconds until the lineman closes the recloser or 4 hours have passed. After 4 hours, the ﬂashing beacon will automatically shut OFF. The beacon is also utilized when the recloser is manually opened. When manually opened, the beacon will continue to ﬂash until the recloser is closed or 4 hours have passed.

Overview

The VERSA-TECH® Recloser can be ﬁtted with an optional radio which will allow settings, diagnostics and scratchpad to be viewed remotely while the unit is in service. The radio will also allow settings, timestamp and scratchpad to be changed while the recloser remains in service. The remote radio options are Digi/XBee 900MHz, SiFLEX 900MHz, or Wireless (WiFi) 2.4GHz. The remote radio is adapted to the serial port on the recloser. In order to accomplish communication with the Digi/XBee or SiFLEX remote radios, a separate Digi/XBee or SiFLEX local radio is needed. The local radio is a USB powered radio that is attached to the laptop or other personal computer running the Versa-Tech Programmer User Interface. Communication with the WiFi remote radio is accomplished through the Wireless Network on the laptop or personal computer.

Customer Supplied Requirements

Personal computer with Microsoft® Windows® XP, Windows® 7 32/64 bit or Windows® 8 operating system, a USB to RS-232 serial cable if a direct connection is desired, PC wireless card for connection through the WiFi remote radio, local Digi/XBee radio with USB Type B serial cable for connection through the Digi/XBee remote radio, or local SiFLEX radio with USB Type B serial cable for connection through the SiFLEX remote radio.

Software Installation

To Establish Communications

If external local radios are required, they must be connected before launching the programming software. If a WiFi remote radio is utilized, connection to the wireless network card on the PC must be established prior to launching the programming software. Once the programming software is launched, click "Refresh List" on the User Interface to scan for the reclosers within the range and "Auto Connect" to connect to the selected detected devices. See Control, Programming > Connection Section 6 of this manual.

Connecting Local Radio

The local radio is controlled and powered by connecting a USB cable between the module and a personal computer as shown in Figure 6-1. Communication with the local radio is accomplished through the recloser programmer software (see section 6) provided with the recloser.

Connecting WiFi

The Versa-Tech Recloser uses a 2.4GHz RN171 remote radio to communicate over WiFi (without the need for a local radio). Wireless communication is established to the Versa-Tech I (FW 3.xx or 4.xx) and Versa-Tech LT through the internal wireless card on a PC and the Versa-Tech Programmer software (UI version 4.50.15 or higher). Wireless communication with a Versa-Tech I with ﬁrmware version

4.xx and Versa-Tech LT can be also be established using the VersaTech Recloser Programmer Version 3.1 iPad app. The WiFi radio has the capability to communicate up to 100 feet from the recloser.

Recloser programming software must be installed on the computer proir to use. Installation software is provided with each recloser on a Hubbell USB drive or is available on the Hubbell Power Systems website.

Connecting Recloser to PC

The customer supplied DB9 Male/Female serial cable is used to directly connect the recloser to a PC (hardwired). Wireless communications can be established utilizing the appropriate 900MHz remote/local radio combination or the PC wireless networks/WiFi remote radio combination.

Remote Radio Power

When the VERSA-TECH® Recloser is in service with a load current of 10 Amps or more, the attached remote radio is on and powered from the recloser's internal current transformers. If the recloser is not in service or the load current is less than 10 Amps, the radio is ON only for 10 minutes and must be powered from the recloser internal batteries. To turn on the radio, pull down the Non-Reclosing handle (red lever) and then push it up. The radio then will automatically shut off after 10 minutes of communications inactivity to minimize battery drain. If the Non-Reclosing Lever is left in the down position without the ample 10 Amps of load current, wireless communications will time out in 60 minutes.

NOTE: Whenever the remote radio on the recloser is changed or swapped with another remote radio, make sure that the battery is pulled out of the recloser for at least 60s for the control to completely reset. After the reset, plug in the new remote radio to the DB 9 port of the recloser followed by the battery pack insertion. This process lets the remote radio get correctly identiﬁed by the Versa-Tech Programmer.

Radio Operation

The Digi/XBee and SiFLEX radios communicate with each other on a 900MHz channel which utilizes frequency hopping to minimize interference from other radio frequency sources. The RF modules are FCC compliant. The communication range is up to 500 feet open air. The radios use a two-part addressing scheme to help ensure that messages from only authorized sources are passed to a recloser.

First, all VERSA-TECH® Recloser local and remote radios have a unique user transparent address which is transmitted during communications. The recloser local radio will accept messages only from a remote radio with the same address. This helps prevent other 900MHz radios from making unauthorized communications with VERSA-TECH® Reclosers.

Second, each remote radio is programmed with a unique ﬁxed radio communications address. This address allows users to differentiate between multiple reclosers all within a 500-foot transmit/receive range. The remote radio will discard any message that does not include its unique radio communications address. The local radio has provisions through the recloser programmer software (see Section 6) which permits selecting any recloser's remote radio communications address.

Settings Tab

Programming Settings

The Recloser Settings Tab appears when the Recloser Programmer Software is loaded and opened. See Figure 6-2. At this point, changes to the settings can be made as required for the recloser’s particular application. When settings changes are complete, the “Write Settings To Recloser” button will allow the settings displayed to be stored in the recloser. Notice that settings ﬁelds that are not identical to what is actually stored in control memory are displayed in red until they are committed to memory. From this point forward the recloser will use these new stored settings. These settings can be checked at any time by clicking the “Read Settings From Recloser” button.

Minimum Trip Value

The Minimum Trip Value is the minimum current sensed that will cause the Recloser to trip. This current is programmable from 30A to 800A for Versa-Tech I and 30A to 200A for Versa-Tech LT in 10A increments. The control will begin counting towards meeting the selected time current curve when there is a half cycle of current above this threshold. The current level is measured by sampling and ﬁnding its peak value. The sample frequency for current measurement is 1.04ms. This gives 16 samples per 60Hz cycle. Sliding window approach is followed to perform current measurement. Current measurement is on half-cycle basis. Hence, to assert a fault (current above Min. Trip), at least 8 samples are required.

Non Reclose/Hot Line Tag

Operations to Lockout

The control can be set to 1, 2, 3, or 4 operations before the recloser goes to lockout.

Manual Closing Delay Time

The time from when the manual handle is activated until the recloser begins closing the circuit can be programmed from 0 to 30 seconds. The actual delay may be a few seconds longer than the time programmed.

Sequence Coordination

The sequence coordination feature if enabled will prevent unnecessary operations of the recloser when used in a series arrangement upstream from other fault interrupting device. If the recloser senses current above the minimum trip level for a duration shorter than the programmed control response time, then the recloser will internally advance its software count by one without tripping. This action allows an upstream recloser to stay in proper sequence when faults are cleared by downstream recloser. False counting is avoided by applying hysteresis to the minimum trip threshold. The current must increase above the minimum threshold and then decrease to 87.5%of the trip threshold before a count is registered. The count is remembered for the reset time.

Versa-Tech I Reclosers with FW 3.xx and VersaTech LT Reclosers:

The Non-Reclose handle has a dual functionality when the option ‘Non-Reclose/Hot Line Tag’ is selected by the proper radio buttons on the main "Settings" tab of the user interface. In this mode, when the red handle is pulled to the down position once (rotate 90° in the clockwise direction) the recloser is placed in the traditional Non-Reclose mode using whichever curve is selected to lockout on TCC1 (See Recloser Operation Section). However, if the red handle is cycled (pull the handle down and up) twice and the handle is brought back to the down position within 30 seconds, the unit is now placed in Hot Line Tag (HLT) or the instantaneous trip mode. When the user selects the ‘Hot Line Tag Only’ option in the Settings, the Non Reclose handle will function always as HLT when the handle is pulled down( rotated 90° in the clockwise direction). A unit placed in HLT mode is always accompanied by a characteristic pulsed strobe of the beacon serving as a visual indicator conﬁrming the HLT mode. Hot Line Tag takes precedence over Cold Load time.

Note for Versa-Tech I Reclosers with FW 4.xx:

When the recloser locks out on a HLT mode dropping the Manual Operating handle (yellow), the unit would be able to close back in only after the HLT mode is removed meaning that the NonReclose handle (red) has to be manually returned to the normal position to disable the HLT function and then the Manual Operating Handle is to be rotated 90° in the anti clockwise direction for the recloser contacts to close back in.

NOTE: Units manufactured prior to August 2011 will not have the dual functionality of the Non-Reclose Handle. However, these units would have dedicated options for the Non-Reclose and Hot Line Tag modes that can be enabled through the User Interface.

When "Sequence Coordination" box is checked, sequence coordination is applied to all programmed shots.

Versa-Tech I Reclosers with FW 4.xx:

Sequence coordination is allowed to be made shot speciﬁc by using the software and choosing the TCC curves where the Sequence Coordination should operate on. This is accomplished by selecting the check boxes for Sequence Coordination under the respective TCC curves on the User Interface. Sequence coordination would be applicable only on the checked TCC curves.

By checking the SC on lockout option, the recloser would trip on TCC2 for a permanent fault that the unit would see past the operations to lockout. For example: If the unit has 4 operations to lockout with the SC Lockout option checked and the unit sees a permanent fault that didn’t clear after 4 downstream operations by the downstream devices, the recloser unit would lockout out on the delayed TCC2 curve which would appear as a 5th actual operation after recording 4(SC) events in the event log.

However, user can uncheck this option on the User Interface and the recloser would continue to record all the downstream blinks or the faults that didn’t engage Versa-Tech TCC curves on the line as 5(SC) 6(SC) 7(SC) so on. Note that the unit would still lockout on the delayed curve (TCC2) when the unit sees a permanent fault which was not cleared by the downstream devices in either situations. (See Control Programming > Event and Data Logs > Sequence Coordination Events Logs Section).

PSP8620311

6 — Control Programming

Time-Current Curve Selection

The control can be set to utilize two different time current curves TCC1 and TCC2. TCC1 and TCC2 can be set separately to use one of 15 different time current curves. See Reference Bulletin TD10005E through TD100034E. Each of the 4 possible operations can be set to use either TCC1 or TCC2.

Time-Current Curve Modiers

Out of the 15 TCC curves, 11 of the curves come in with modiﬁers for greater coordination ﬂexibility. By selecting Mod1, Mod2 or Mod3, the shape of the time-current curve can be modiﬁed as shown in Reference Bulletin TD10005E through TD100026E.

Minimum Response Time

Minimum response time is used to achieve coordination between fault interrupting devices where fault levels would cause two devices in series to both trip. When minimum response is enabled, tripping is inhibited until the minimum response time programmed is less than or equal to the fault current time. The minimum response time is programmable from 0 to 250 milliseconds in 1 millisecond steps and can be enabled on operation 1, 2, 3, or 4. Minimum response can be enabled to each of the speciﬁc time current curves of the counts by checking the Enable Min. Response option individually under each curve.

Basically, when a minimum response time is entered and the minimum response box is checked, the recloser will not open on the selected shot until the minimum response time or the TCC time for that shot, whichever one is greater.

Reclose Time

Reclose Time is the amount of time from when the recloser interrupts the over-current until the recloser attempts to close the circuit again. Each of the three possible reclose intervals is separately programmable from 0.25 to 60 seconds in 0.05 second increments.

Reset Time

Reset time is the amount of time from the last reclose until the present count of operations completed is reset to zero and it is also deﬁned as the amount of time from the last momentary over current event (current above minimum trip) the recloser sees until the timer expires. When the recloser goes to lockout, the count is also reset to zero. Reset time is programmable from1 to 240 seconds in 1-second increments.

PSP8620311 Rev. E

6 — Control Programming

Cold Load Time

During this programmed interval, pick-up threshold is elevated to Cold Load Pickup value and the control is placed in one operation to lockout mode. Over current timing of TCC2 is used by the control. Cold Load Pickup is active after the recloser has been opened manually or has been locked out. Cold Load Time is not valid while the recloser is performing it's reclose operations. If no over current is present during this interval, the control will reset after cold time expires. Cold Load Time is programmable from 0 to 300 sec. for VTI (FW 3.xx) and VTLT and 0 to 600 sec. for VTI (SCADA FW 4.xx) in 1 second increments. Cold load time takes precedence over the Non-Reclosing lever function.

Cold Load Pick up

NOTE: Cold Load Pick Up is only enabled for Versa-Tech I Reclosers with FW 4.xx.

The range of the minimum trip can be elevated by multiplying the minimum trip by the cold load pick up factor during the Cold Load Time. The Cold Load Pickup factor ranges from 1-20 and is programmable in steps of

1.For example: A recloser programmed at a minimum trip of 50A, cold load time of 100 sec with the cold load pick up of 2 has a minimum trip range from 1A-100A during the 100sec cold load time when the unit has locked out (or manually opened) and closed back in.

Record Manual Close

When enabled, this feature causes the recloser to store in the Event History the time and date of manual closes as well as over-current operations. When disabled, only over-current operations are stored.

Time Stamp

The recloser has a built in time stamp circuit which records the time and date following each recloser operation. The time stamp on the recloser can be set in two ways.

1. Every time the User Interface communicates with the unit, the Programmer generates a pop up question to auto sync the host computer's clock with the real time clock on the recloser.

2. The real time clock can also be set to the Local or the UTC time zones by selecting the proper radio button on the User Interface and writing them to the recloser by the clicking "Set Recloser Time zone " under the Time and Security tab. (See Section Time and Security.)

NOTE: Make sure that the host computer has accurate time and date before using the "Set Recloser Timezone " or the Auto Sync option. The recloser would be able to keep the time only when the time is set wirelessly through the radios and with the provided battery pack inside the unit. INVALID times would be seen on the Recloser Time section when times are set through an RS232 serial connection.

The time stamp utilizes one of 3 power sources to maintain correct time. When the recloser is in service internal current transformer power is used. When the recloser is open or not in service the main lithium batteries are used. If both of these power sources are unavailable the control has a capacitor backup circuit, which can power the time stamp for up to 7 days.

NOTE: Once the time stamp has been set, it is important that the lithium battery bayonet not be removed for more than 7 days. If the time stamp loses power, the recloser will continue to function correctly, but the times and dates stored for recloser operations will be INVALID.

Note for Versa-Tech I Reclosers with FW

4.xx: The lithium battery bayonet should not

be stored in the recloser while the unit is not in service. FW 4.xx does not incorporate low power optimization which will result in decreased battery life. When the recloser is ready to be put in service, insert the battery bayonet and connect to the recloser to sync the time stamp. See Section 8 Maintenance > Battery Replacement Section for additional information regarding VTI with ﬁrmware 4.xx.

Real Time Monitoring

* For Versa-Tech® I: RMS Current "Now" is 400A Max For Versa-Tech® LT: RMS Current "Now" is 200A Max

Instantaneous Current Monitoring

The real time monitoring features are automatically updated following a successful connection.

Now: It is the Root Mean Square current (RMS) calculated every one second.

Last hour: It is average of RMS current calculated for every one second and averaged over 3600 sec (1h=60x60) i.e., an hour. The

Last hour average current is updated every 10 sec only for the very ﬁrst one hour when the recloser sees the current since it would not see the 3600 entries for times less than one hour.

Peak: It is the mean square current seen for every one second interval which is always compared against the previous mean square current and the greater of the two is displayed.

The peak and the last hour rolling average values can be reset using the appropriate reset buttons for each.

Events and Data Log

Viewing Diagnostic Events and Data Log

The recloser also has some built in diagnostic features, which can be read by selecting the Events and Data Log Tab as shown in Figure 6-4. This ﬁeld will display the recloser operations count, the energy of interrupted faults, and the hourly log data ﬁeld. Separately, the resettable operations counter can be reset and the data log erased by clicking the appropriate buttons. In addition to the fault history previously available, there is now a viewing window for an hourly log (Load Proﬁle). Due to required upload times options are given for the last week, last 2 weeks or entire log (45 DAYS) to be retrieved. This log will be included in the full report generation only after it has been separately downloaded. The Generate Full Recloser Report will not include the hourly log unless it has been previously downloaded. Sequence coordination events will be registered and marked as such in the events log.

Scale is the amount of Amperes set as a reference for the graphical display of the hourly log.The graph would populate only after the hourly log has been downloaded.

Total Count: The total count reﬂects the total number of times the bottle has been electronically opened on a fault operation. This is driven by the microprocessor control.

This Count: This Count is the number of times the bottle has electronically opened from the last Reset. This Count can be Reset by using the Reset button as in Figure 6-4.

Note: The external mechanical counter on the Versa Tech increments whenever the bottle has been opened either electronically or manually by using the Manual Handle . So it is likely that the counts on the electronic and the mechanical counter differ when the Manual Handle has been used to open the bottle.

7 — Testing

High Potential Withstand Test

Applying AC 50/60 Hz voltage across the open contacts of the recloser will test the dielectric integrity of the vacuum interrupter. The AC voltage should be applied at 40kV which is 2/3 of the rated maximum withstand for 60 seconds.

1. Open the recloser.

2. Connect the test voltage across the recloser open contacts by attaching one end of the test transformer to each of the 2-hole NEMA input pads (see Figure 7-1).

3. Ensure both ends have adequate electrical clearance from each other and from any ground.

4. Verify the recloser can hold the voltage across the open contacts for 60 seconds.

WARNING

Hazardous voltages are present during testing. Severe personal injury or death can occur from contact with recloser or high voltage transformer during tests.

Recloser and high voltage transformer must be in a grounded test cage or similar protective barrier to prevent accidental contact with energized equipment.

CAUTION

X-rays may be emitted from open vacuum interrupter contacts during high potential withstand tests.

X-rays may be hazardous to your health.

Maintain a minimum of 3 meters distance from recloser during this high potential withstand test.

X-rays emitted by testing at voltages up to 40kV are negligible at the minimum 3 meters distance, but higher test voltages may result in hazardous x-ray emission.

During high potential withstand tests, self extinguishing momentary breakdowns can occur which do not indicate signiﬁcant loss of vacuum.

8 — Maintenance

Service Requirements

The Versa-Tech® Recloser has been designed for a minimum mechanical life of 30,000 operations (Versa-Tech I) and 10,000 operations (VersaTech LT). No routine maintenance is required (other than occasional ﬁrmware upgrade and battery replacement).

Battery Replacement

The batteries are made of a very stable lithium chemistry, which is designed with a low self discharge with a shelf life of 10 years. Hubbell Power Systems is recommending that users replace the batteries on a maximum 8 year cycle (for Versa-Tech I Reclosers with FW 3.xx and Versa-Tech LT Reclosers).

Note for Versa-Tech I Reclosers with FW 4.xx only: Versa-Tech I FW 4.xx

was developed for SCADA compatibility. It does not incorporate low power optimization since it requires more diagnostics and data collection. In cases of lightly loaded lines, battery power is utilized to perform these functions resulting in decreased battery life.

WARNING

Fire, explosion, leakage and severe burn hazard.

Do not recharge or disassemble batteries. Batteries should not be exposed to temperatures above 212 degrees F. Do not incinerate batteries or expose them to water. Do not short (+) and (-) terminals of batteries. When discarding batteries, insulate the (+) and (-) terminals with insulating tape.

WARNING

High voltage electric contact hazard.

Can cause severe injury or death.

The recloser housing and the battery bayonet are energized when the recloser is in service. Follow all of your utility's recommended safety practices for working with energized apparatus of this voltage class. Use appropriate length grip-all clamp stick or appropriately rated rubber gloves and personal protective equipment.

Figures 8-1 and 8-2 show the battery bayonet and placement in the recloser. The battery bayonet was designed to be replaced using a hot stick while the recloser is in service. The battery bayonet utilizes a twist lock design. It is easily removed by pushing in slightly and turning.

The date of manufacture of the battery bayonet is stamped on its end casting. The date format is "XXXX" where the ﬁrst two numbers represent the month and the second two numbers represent the year.

Battery Disposal

Litihium batteries are neither speciﬁcally listed nor exempted from the Federal Environmental Protection Agency (EPA) hazardous waste regulations as promulgated by the Resource Conservation and Recovery Act (RCRA). The only metal of possible concern in a lithium battery is lithium that is not a listed or characteristic toxic hazardous waste. Waste lithium batteries can be considered a reactive hazardous waste if there is a signiﬁcant amount of unreacted, or unconsumed lithium remaining in the spent battery. The key to disposing of a lithium battery as a nonhazardous waste is to guarantee that it is fully or mostly discharged. Once it is discharged it can be disposed of as non-hazardous waste.
