DANGER

Hazardous high voltage is present at the line terminals of the bushings on the cover of the regulator.

Will cause severe injury or death.

To prevent:

Isolate the regulator before servicing.

Type JFR voltage regulators are routinely equipped with line bushing terminals per the following criteria.

Clamp type terminals for use through 668 ampere are capable of accepting an aluminum or copper conductor.

Tank grounding provision consists of a 0.5-13NC tapped hole in a steel pad for regulators rated to 300 amperes. Above 300 ampere ratings, a copper-faced pad with two 0.5-13NC tapped holes is provided.

Type JFR regulators are commonly installed using any of four electrical configurations.

One regulator in single-phase application. (Figure 4D)

Two regulators in open delta on a three-phase ungrounded system. (Figure 4B)

Three regulators in closed delta on a three-phase ungrounded system. (Figure 4C)

Handling. Type JFR regulators are designed to be lifted either by a forklift at the base or by use of hangar brackets on the side of the tank. Each JFR regulator is provided with either 2 or 4 lifting hooks on the side of the tank. The number of hooks has been established to provide a mar-gin of safety on lifting when all hooks provided are used.

PHYSICAL CONSIDERATIONS

Location. Type JFR regulators are designed for outdoor installation. Any regulator may be platform or pedestal mounted. Regulators provided with hangar brackets are suitable for pole mounting. When the regulator is to be installed in a substation on a pedestal it is recom-mended that a minimum elevation to the live connection be established, as required by applicable codes.

Elevation. When the regulator will be used at an elevation above 1000 meters (3300 feet) the kVA rating must be reduced to assure operating temperature limits are not exceeded.

Falling unit can cause severe injury or damage.

To prevent:

Do not use cover lifting eyes tolift complete unit.

Cover lifting eyes are for untanking of regulator only.

Lift complete regulator by using all side tank hooks.

WARNING

For air cooled (OA) rating, derate kVA rating 0.4% for every 100 meters (330 feet) elevation above 1000 meters.

For forced air cooled (FA) rating, derate kVA rating 0.5% for every 100 meters (330) feet elevation above 1000 meters.

PROTECTIVE MEASURES

Bypass Arrester. All JFR regulators are equipped with a properly sized arrester, connected externally between the 'S' and 'L' line terminals. The arrester is provided to protect the series winding of the regulator from line surges. Of itself, the bypass arrester does not provide lightning protection for the regulator.

Lightning Protection. The number of lightning arresters used will be a judgmental decision on the part of the user, consid-ering such factors as isokeraunic level and degree of risk of damage to be accepted. The minimum recommended light-ning protection consists of a properly sized arrester between the 'S' or 'L' bushing and ground on a single phase or a wye connected system. A delta connection system requires the use of two arresters to accomplish minimum protection lev-els. Additional protection can be obtained with the use of arresters at both the 'S' and 'L' terminals in single phase or wye systems and on all three terminals on a delta system.

For best results, install lightning arresters on the mounting lugs adjacent to the bushings near the top of the tank. The lugs are 0.5 - 13NC located on 2.5 inch centers. Ground the arrester(s) and the regulator tank solidly to the same ground connection. Be careful to keep the ground lead connections as short as possible.

Thru Fault. Type JFR regulators are rated under condition of thru-faults for twenty five times the OA rated current for 2 seconds or 40 times the OA rated current for 0.8 second to a maximum of 20,000 amperes rms symmetrical. The fault current may be asymmetrical to the extent that the peak of the first current loop is equal to 2.26 times the rms value of the current wave.

The user is advised to provide for additional source imped-ance, bus sectionalizing or other means of limiting the avail-able thru-fault current if these criteria are exceeded at the installation

CONTROL CONNECTIONS

Many regulators can be used at several different nominal system voltages. It is therefore necessary to assure that the regulator is properly connected at the 19 pin upper terminal block for the system voltage on which the particular regulator will be used.

For this purpose, it is necessary to use the nameplate drawing and control diagram found in the control enclosure.

Refer to the Nameplate Diagram. A column is indicated to connect lead P2 to P( ), based on the applicable system voltage. The control diagram will aid in identifi-cation of the appropriate pin on the 19-pin terminal block.

1.

Depending on the regulator, there may be a second column indicating that lead U2 is to be connected to U ( ). The same procedure is followed.

2.

For regulator equipped with fans for forced-air cooling, another set of connections will be shown.

3.

Matters specifically relating to the Accu/ StatTM control used in conjuntions with the regulator are not included in this manual.

Refer to the appropriate control instruction manual.

PLACING THE REGULATOR IN SERVICE

The following checks will be useful in assuring the regulator is ready for use. The list cannot be all inclusive; careful at-tention on the part of a qualified operator remains impera-tive.

BEFORE CONNECTING

Check oil level at oil sight window. If low, add sufficient oil (ASTM D-3487 Type II) to bring level to that desired.

Check dielectric strength of the oil per ASTM D-877. If found to be below 24 kV, filtering should be accomplished and additional testing of oil integrity is justified. Note:

This is not necessary if regulator is being installed im-mediately upon receipt from the factory.

Take power factor reading of all bushings (common) against ground (tank). Reading should be less that 2.0%.

Verify from the nameplate that the unit is connected for the proper output voltage, motor voltage and control panel voltage.

Assure that the regulator is on the neutral tap position.

This should be accomplished by observing the position indication pointer and by powering the control from a 120V external source and observing the NeutraliteTM to be illuminated.

Identify 'S', 'L' and 'SL' bushings on the cover. Make elec-trical connections per the appropriate installation dia-grams, page 4, first connecting 'SL' bushing.

Set Vari-AmpTM limits on position indicator, if necessary.

See Page 11.

Set Accu/StatTM Control as desired. See Accu/StatTM instruction manual

SWITCHING THE REGULATOR

"ON THE LINE"

It is absolutely imperative that the regulator be on the neutral tap position before switching the regulator on the line.

CONNECTING

High pressure or mechanical failure due to improper by-pass operation can cause death, severe injury or damage.

To prevent:

Energize regulator only with regulator on neutral tap posi-tion.

Follow instructions:

1. Make certain regulator is in neutral (N) position.

2. Turn voltage source switch to "OFF".

3. Remove power fuse.

4. Close, sequentially, the source and load switches.

5. Open the bypass switch.

6. Visually observe that bypass circuit has opened.

7. Replace power fuse.

8. Place voltage source switch to normal.

WARNING

CHECKING REGULATOR

OPERATION

Turn the transfer switch to MANUAL.

Run the tapchanger in the lower direction, at least until the control is observed to go out of band "LOW".

Turn the transfer switch to AUTO. After a time delay, the regulator will return to an "IN" band condition.

Turn the transfer switch to MANUAL.

Run the tapchanger in the raise direction, at least until the control is observed to go out of band "HIGH".

Turn the transfer switch to AUTO. After a time delay, the regulator will return to an "IN" band condition.

REMOVING THE REGULATOR FROM SERVICE

WARNING

High pressure or mechanical failure due to improper by-pass operation can cause death, severe injury or damage.

To prevent:

Bypass regulator only with regulator on neutral tap posi-tion.

Follow instructions:

REMOVING THE REGULATOR

FROM THE LINE

In order to remove a regulator from service without dropping load, it is imperative that the regulator be on the neutral posi-tion. The system must first be de-energized (load dropped) before removal. If the regulator being removed is in a closed delta bank, it is necessary to bypass and isolate all regula-tors in the bank. The routine removal procedure is essen-tially the reverse of the procedure used to place the regulator on the line.

Run the regulator under normal voltage source to the neutral position, as revealed by the tap position indica-tor.

1.

Confirm via the NeutraliteTM indicator that the regula-tor is on neutral. If the independent checks of the po-sition indicator and NeutraliteTM indicator do not con-firm the neutral position, bypassing must not be at-tempted. In such event, de-energize the system to re-move the regulator from service.

2.

After assuring that the regulator is on neutral, close the bypass switch.

Open, sequentially, the load and source switches.

3.

4.

5.

6. Exercise appropriate care in the removal of the regulator. High voltage will still be present at the bypass witch and the source and load switch terminals. Remove the ground connection last.

(b.) For a closed delta connection, be sure all regula-tors in the bank are bypasses and isolated.

(a.) For a single phase or grounded wye connection, make sure that the high voltage disconnect switches are opened.

MAINTENANCE

GENERAL INSTRUCTIONS

Failure to properly maintain the regulator can result in se-vere personal injury and product failure. The instructions contained herein should be carefully reviewed, understood and followed. The following maintenance procedures should be performed regularly:

1. Operational checks

• Control performance

• Tapchanger performance

• Vari-AmpTM limit performance.

2. Periodic inspection

• Oil sample

• Oil oxidation inhibitor addition

• Contact wear

• Fans

This checklist does not represent an exhaustive survey of maintenance steps necessary to ensure safe operation of the regulator. Particular applications may require further pro-cedures. Should further information be desired or should particular problems arise which are not covered sufficiently for the purchaser’s purposes, the matter should be referred to the local Siemens sales representative.

When powered, dangerous voltages are present in the equip-ment that can cause severe personal injury, death, and prod-uct failure. Always de-energize and ground the equipment before maintenance requiring access to high voltage parts.

The use of unauthorized parts in the repair of the equipment, tampering by unqualified personnel, or faulty repair and ad-justments will result in dangerous conditions which can cause severe personal injury or equipment damage. Follow all safety instructions contained herein.

OPERATIONAL CHECKS

Basic regulator operation can be checked while the regula-tor remains in service. Simply provide means to observe the output voltage (such as a voltmeter connected at the test terminals).

• Observe that the voltmeter reads the voltage level setting required by the control, to within one-half of the band-width tolerance. Note 1: The control must be “in” band.

Note 2: Line drop compensation must be set to zero if the regulator is carrying load.

• Run the tapchanger several steps in one direction in the manual mode until the output voltage is outside of the bandwidth. Return the control to automatic mode. After the predetermined time delay, the tapchanger motor will be observed to return the output voltage in-band. Repeat this operation, running the tapchanger in the opposite direction.

• Check the Vari-AmpTM limit switches by attempting to run the tapchanger beyond the position to which the switches are set. The limit switches should function to open the circuit. Note: If the limit switch is set at the maximum 10% range and fails to function, the tapchanger will stall against a mechanical stop. The motor is designed to stall con-tinuously without damage

CAUTION

WARNING

Operation of the regulator at extreme tap positions could produce a line voltage above or below desired operating limits at the load.

To prevent:

Operate the regulator only to judiciously determined voltage extremes.

Regulator may have High Internal Pressure. Can cause serious personal injury or death, or damage to the regulator.

To prevent:

Use pressure relief valve to vent regulator before untanking.

www .

El ec tric alP ar tM an ua ls

A sample of oil from the regulator should be subjected to dielectric breakdown test, per ASTM D-877. It is recom-mended that oil testing less than 24 kV be filtered. Other tests, especially Neutralization Number, Interfacial Tension and Power Factor are also useful and may be preferred by particular users.

The oxidation inhibitor in the oil will be depleted over a pe-riod of a few years and should be replaced. The inhibitor is 2, 6-ditertiary-butyl-para-cresol (DBPC) at a concentration level of 0.2 to 0.3%.

The time interval between internal inspections will depend upon frequency of tapchanger operation and the load on the regulator. Regulators subjected to numerous overloads and a high load factor may require more frequent inspections than those carrying normal loads. While internal inspection is not a necessity, preventive maintenance inspections will help assure the continuity of service.

PERIODIC INSPECTION

If cover top cap is removed, make certain the cap is properly sealed when replaced on cover. Siemens recommends ap-plying pipe sealant (Loctite PST or equivalent) around the threads of the adapter. Furthermore, it is recommended that the seal be tested by applying 5 psig pressure through the pressure relief valve fitting for 5 minutes, with no loss in pressure. Failure to assure seal may allow moisture to be pulled into the unit during a cool-down cycle.

Remove the regulator from service as described on Page 7.

Place the regulator in a position where energized overhead lines will not interfere.

1.

2.

Operate pressure relief valve to vent regulator before untanking

3.

Remove the three mounting bolts holding the control box onto the main tank.

4.

Loosen all cover bolts and turn outward 180 degrees.5.

The regulator can now be pulled from the main tank by the cover lifting eyes.

6.

When inspecting, check to be certain all hardware and con-nections are tight. The principal point of the internal inspec-tion will be the condition of the arcing contacts on the tapchanger. Since numerous factors influence the rate of contact tip wear, no one criteria can be stated to recom-mend when a contact should be changed.

The following figure shows the possible condition of con-tact wear after a period of operation. If a contact surface has burned down so that only a 1/8 inch wide line contact area remains, the contact will probably be giving adequate ser-vice at low contact temperatures, but much further deterio-ration will probably result in decreased spring pressure and possibly faulty operation. Therefore, the contact should defi-nitely be replaced. (See Figure in next column.)

Contacts, both movable and stationary, show normal burning and wear after 1,500,000 operations. If for any reason A1 dimensions exceeds 4/5 of A, the stationary contact should be replaced.

SEALED REGULATORS WITH

PRESSURE RELIEF VALVE

To untank a JFR regulator, proceed as folllows:

The fans used for cooling (on some regulators) require a minimum of attention. Fans with plain sleeve bearings or Oil-Lite sleeve bearings should be oiled at least once a year with a good grade of SAE 10-W mineral engine oil which does not thicken in cold weather. Oil must be added to sleeve bearings before starting motor for the first time after installation.

Fans equipped with ball bearing motors are packed with grease before shipment and should be greased at least once a year with a soda-soap, ball-bearing grease of me-dium consistency furnished by a reliable supplier.

For fans that are seldom used, the frequency for greasing or oiling may be less than outlined above, but it is recom-mended that this lubrication be placed on a yearly schedule.

It is often possible to determine by inspection whether lubri-cation is required.

SPECIAL FEATURES

The Accu/StatTM control panel is hinged and may be re-moved completely from the regulator control box by remov-ing the wing nuts on the polarized jack plug and pulling the jack from its fixed portion. This will automatically de-energize the control. It is not necessary to bypass or de-energize the regulator to remove the control.

A spring-loaded shorting bar in the plug automatically short circuits the current transformer secondary when the jack is removed.

The Accu/StatTM control may be remotely mounted. Remote cable is available in standard lengths of 18, 25 and 30 feet incorporating oil and moisture resistant, color-coded conduc-tors.

REMOTE MOUNTING

OF CONTROL

EQUIPMENT

VARI-AMPTM POSITION INDICATOR

The Vari-AmpTM feature provides a method of operating the regulator at increased load by decreasing the range of op-eration. It provides operator flexibility by allowing the range of regulation to be adjusted in 1 1/4 percent increments. The various regulation ranges together with the corresponding current capacities for standard regulators are listed on page

11. All that is necessary to adjust the range of regulation anywhere from ±5 percent to ±10 percent is to turn the ad-justing knobs until the proper range of regulation is shown on the side of the position indicator. The upper and lower limits need not be the same.

It is not necessary to remove the regulator from service to make this adjustment. The switches are, however, in the motor power circuit so the motor should not be running while the switches are being set.

OPERATION AT LESS

THAN

RATED VOLTAGE

JFR regulators may be operated at less than the voltage for which they were de-signed. All system voltages for which control system taps have been provided are shown on the nameplate. When this is to be accomplished it may be neces-sary to reconnect particular leads at the upper 19-pin terminal block as illustrated on page 5. When operating the regula-tor at reduced voltage it must be noted that the regulator carries a maximum current rating which rules regardless of the voltage (see table at right). It may therefore be necessary to operate the regulator at less than its nameplate kVA rating.

Units with catalog number starting with 10 are self cooled 11 are forced-air cooled

Regulators can be modified at factory for 50 Hz operation with appropriate derating of voltage.

El ec tric alP ar tM an ua ls

Certain regulators may be equipped for forced-air cooling and include fans mounted on the radiators. The fans are usually automatically controlled by means of the change in oil temperature (see Connection Diagram). The thermom-eter located in the top transformer oil contains two identical switches which control fan operation when fan control switch is in “Auto” position.

The switches are normally set to start the fans at 65°C and to stop them at 55°C top oil temperature, but may be ad-justed plus or minus 5°C.

A thermal overload relay is mounted on each fan motor. Any fan that develops trouble will be automatically disconnected from the line without affecting the other fans of the system.

One fan can be removed from the radiators without affecting the operation of the others. When fans are out of service, care must be exercised to prevent overloading the regulator.

Fan should be removed and replaced carefully to prevent damage to the radiators.

FORCED AIR COOLING SUBBASE ASSEMBLY

Subbase assemblies are available in 4-inch high increments from 21 through 49 inches for most JFR regulators. The proper height is selected by picking the elevation that will provide required clearance from foundation to the live part of the regulator bushing.
