PHYSICAL CONSIDERATIONS
• Handling. Type JFR regulators are designed to be lifted either by a forklift at the base or by use of lifting hooks on the side of each tank. Each JFR regulator is provided with either 2 or 4 lifting hooks on the side of each tank.
The number of hooks has been established to provide a margin of safety. Use all supplied lifting hooks when lifting.
WARNING
Improper use of lifting provisions can cause death, serious injury, or equipment damage.
To prevent:
Do not use cover lifting eyes to lift complete unit.
Cover lifting eyes are for untanking only.
LINE TERMINALS AND
CONNECTIONS
Type JFR voltage regulators are routinely equipped with line bushing terminals per the following criteria.
Nameplate Line Current
Rating
50A to 300A
301A to 668A
669A to 1200A
1201 A to 2000A
Conductor Size Range or Threaded Stud Size
#2 to 477 MCM
#2 to 800 MCM
1.125- 12 UNF-2A
1.500- 12 UNF-2A
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 stainless steel pad with two
0.5-13NC tapped holes is provided.
• Location. Type JFR regulators are designed for outdoor installation. Any regulator may be platform or pedestal mounted. Regulators provided with hanger brackets are suitable for pole mounting. When the regulator is to be installed in a substation on a pedestal it is recommended that a minimum elevation to the live connection be established, as required by applicable codes.
Will cause serious injury or death.
To prevent:
Hazardous voltage present at the line terminals of the bushings on the cover of the regulator.
De-energize the regulator before servicing.
Elevation. When the regulator will be used at an elevation above 1000 meters (3300 feet) the kVA rating must be derated per ANSI C57.15 to assure operating temperature limits are not exceeded.
ELECTRICAL CONSIDERATIONS
Type JFR regulators are commonly installed using any of four electrical configurations.
• One regulator in single-phase application. (Figure 4A)
• Three regulators in wye on a grounded-neutral threephase system. (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)
Each of the four alternatives, when complete with switching provisions, will take the electrical configuration as shown on the next page.
The descriptions 'S', 'L', and 'SL' are embossed into the cover for user convenience at time of installation.

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. By itself, the bypass arrester does not provide lightning protection for the regulator.
Lightning Protection. The number of lightning arresters used will be a discretionary decision on the part of the user, considering such factors as isokeraunic level and degree of risk of damage to be accepted. The minimum recommended lightning 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 levels. 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.
Figure 5A
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.
For this purpose, it is necessary to use the nameplate drawing and control diagram found in the control enclosure.
Thru Fault. Type JFR regulators are rated under condition of thru-faults per ANSI C57.15.
1. Refer to the Nameplate. The P2 column indicates the correct connection for lead P2 based on the system voltage. Using the applicable control diagram, the terminal designation of the nameplate can be cross referenced to the proper terminal on the 19-pin terminal block.
The user is advised to provide for additional source impedance, bus sectionalizing or other means of limiting the available 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.
2. Depending on the regulator, there may be a second nameplate column indicating that lead U2 should also be connected. If so, the U2 column indicates the correct connection for lead U2 based on the system voltage
Using the applicable control diagram, the “U” terminal designation of the nameplate can be cross referenced to the proper terminal on the 19-pin terminal block.
3. For regulator equipped with fans for forced-air cooling, another set of connections will be shown.
NOTE
Matters specifically relating to the Accu/Stat
TM control used in conjunction with the regulator are not included in this manual. Refer to the appropriate control instruction manual.

PLACING THE REGULATOR IN SERVICE
Page 9
The following checks will be useful in assuring the regulator is ready for use. The list cannot be all inclusive; careful attention on the part of a qualified operator remains imperative.
BEFORE CONNECTING
•
Check oil level at oil sight window. If low, add sufficient oil
(ASTM D-3487 Type II) to bring to desired level.
•
Check oil dielectric strength per ASTM D 877. If found below 25kV, oil should be changed or reconditioned.
Reference ANSI C57.106-2002. Note: Oil tests are not required for new equipment.
•
Perform insulation power factor test per ANSI C57.15.
Maximum value is 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 indicator pointer and by powering the control from a 120V
TM external source and observing the Neutralite to be illuminated.
•
Identify 'S', 'L' and 'SL' bushings on the cover. Make electrical connections per the appropriate installation diagrams, page 4, first connecting 'SL' bushing.

GENERAL INSTRUCTIONS
This manual does not represent an exhaustive survey of maintenance steps necessary to ensure safe operation of the regulator. Particular applications may require further procedures. 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.
WARNING
Failure to properly maintain the regulator can result in serious injury, death, or equipment damage. The instructions contained herein should be carefully reviewed, understood and followed.
To prevent:
The following maintenance procedures should be performed regularly:
1. Operational checks.
2. Periodic inspection.
Page 11
OPERATIONAL CHECKS
Basic regulator operation can be checked while the regulator remains in service. The output voltage can be monitored from the control panel display under the <METER> menu on the
“Vld” screen.
• Check the calibration by following the steps in the Basic
Troubleshooting section of the Accu/Stat control panel instruction manual.
• 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-Amp
TM
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 continuously without damage.
Hazardous voltages. Will cause serious injury, death, or equipment damage.
To prevent:
Always de-energize and ground the equipment before maintenance requiring access to high voltage parts.
WARNING
The use of unauthorized parts in the repair of the equipment, tampering by unqualified personnel, or faulty repair and adjustments can result in dangerous conditions which can cause serious injury, death, or equipment damage.
To prevent:
Follow all safety instructions contained herein, and contact your local Siemens sales representative for replacement parts.
CAUTION
Operation of the regulator at extreme tap positions could produce line voltages outside of operating limits that could result in property damage.
To prevent:
Operate the regulator only to judiciously determined voltage extremes.
WARNING
Regulator may have High Internal Pressure. Can cause serious injury, death, or equipment damage.
To prevent:
Use pressure relief valve to vent regulator before untanking.
M A I N T E N A N C E
Page 12
PERIODIC INSPECTION
A sample of oil from the regulator should be subjected to dielectric breakdown test, per ASTM D-877. If found below
25kV, the oil should be changed or reconditioned. Refer to
ANSI C57.106-2002. 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 period of a few years and should be replaced. The inhibitor is 2, 6ditertiary-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.
To untank a JFR regulator, proceed as folllows:
1. Remove the regulator from service as described on
Page10.
When inspecting, check to be certain all hardware and connections are tight. The principal point of the internal inspection 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 recommend when a contact should be changed.
The following figure shows the possible condition of contact wear after a period of operation. If the contact surface is less than 1/8 inch wide, the contact should be replaced. (See the Figure below)
Contacts, both movable and stationary, show normal burning and wear once placed in service. If for any reason A1 dimensions exceed 4/5 of
A, the stationary contact should be replaced. (See the Figure below)
A
A1
Hazardous voltages. Will cause serious injury, death, or equipment damage.
To prevent:
Always de-energize and ground the equipment before maintenance requiring access to high voltage parts.
2. Place the regulator in a position where energized overhead lines will not interfere.
3. Operate pressure relief valve to vent regulator before untanking
4. Remove the mounting bolts holding the control box onto the main tank.
5. Remove all cover bolts.
6. The regulator can now be pulled from the main tank by the cover lifting eyes.
• UPPER FILTER PRESS SEALING
If cover top cap is removed, make certain the cap is properly sealed when replaced on cover. Siemens recommends applying 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.
• FAN MAINTENANCE
Cooling fans (if equipped), require minimum attention. Fans with plain sleeve bearings or Oil-Lite sleeve bearings should be oiled at least once a year with SAE 10-W 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 medium consistency furnished by a reliable supplier.

POLARIZED DISCONNECT SWITCH
VARI-AMP
TM
POSITION INDICATOR
(JACK PLUG) AND HINGED
CONTROL PANEL
The Accu/Stat
TM
control panel is hinged and may be removed completely from the regulator control box by removing the wing nuts on the polarized jack plug and pulling the jack from its fixed position. 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 Vari-Amp
T M feature provides a method of operating the regulator at increased load by decreasing the range of operation. It provides operator flexibility by allowing the range of regulation to be adjusted in 1¼ percent increments. The various regulation ranges together with the corresponding current capacities for standard regulators are listed on the next page. All that is necessary to adjust the range of regulation anywhere from ±5 percent to ±10 percent is to turn the adjusting 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.
REMOTE MOUNTING
OF CONTROL
EQUIPMENT
The Accu/Stat
TM
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 conductors.

OPERATION AT LESS
THAN
RATED VOLTAGE
JFR regulators may be operated at less than the voltage for which they were designed. 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 necessary to reconnect particular leads at the upper 19-pin terminal block as illustrated on page 5. When operating the regulator 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 de-rating of voltage.
*Capable of carrying current corresponding to rated kVA when operated at 7200/12470 volts ground wye.

FORCED AIR COOLING SUBBASE ASSEMBLY
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 thermometer located in the top transformer oil contains two identical switches which control fan operation when fan control switch is in “Auto” position.
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.
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 adjusted 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.
