INSPECTION FOR
DAMAGE IN SHIPMENT
STORAGE PRIOR TO
INSTALLATION
Check each item with the shipping manifest immediately
upon receipt of the regulator. Make a thorough visual inspection of the regulator. Check for evidence of damage
attributable to mishandling in shipment. Should any shortage or damage be found, notify the local agent of the carrier
making the delivery and make appropriate notation on the
freight bill. A claim should be made immediately with the
carrier. Siemens should be notified
The regulator may be stored without any particular precautions or protection. Assure, however, that the control
compartment enclosure is tightly closed.
INTRODUCTION
PHYSICAL CONSIDERATIONS
•
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 margin of safety on lifting when all hooks provided are used.
WARNING
Page 3
•
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.
LINE TERMINALS
AND CONNECTIONS
Type JFR voltage regulators are routinely equipped with line
bushing terminals per the following criteria.
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.
•
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 recommended that a minimum elevation to the live connection
be established, as required by applicable codes.

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.
ELECTRICAL CONSIDERATIONS
DANGER
Hazardous high voltage is present at the line terminals
of the bushings on the cover of the regulator.
Type JFR regulators are commonly installed using any
of four electrical configurations.
•
One regulator in single-phase application. (Figure 4D)
•
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)
Will cause severe injury or death.
To prevent:
Isolate the regulator before servicing.
•
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.
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. 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, 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.
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.
Figure 5A
For this purpose, it is necessary to use the nameplate
drawing and control diagram found in the control enclosure.
1. 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 identification of the appropriate pin 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
2.
CONTROL CONNECTIONS
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.
3.
For regulator equipped with fans for forced-air
cooling, another set of connections will be shown.
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.
NOTE
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
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
WARNING
High pressure or mechanical failure due to improper bypass operation can cause death, severe injury or damage.
To prevent:
•
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 immediately 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.
Energize regulator only with regulator on neutral tap position.
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.
CHECKING REGULATOR
OPERATION
(Refer to applicable Accu/StatTM Control instruction manual.)
CONNECTING
•
•
•
1.
Turn the transfer switch to MANUAL.
Identify 'S', 'L' and 'SL' bushings on the cover. Make electrical connections per the appropriate installation diagrams, page 4, first connecting 'SL' bushing.
2.
Run the tapchanger in the lower direction, at least until
the control is observed to go out of band "LOW".
3.
Set Vari-AmpTM limits on position indicator, if necessary.
See Page 11.
Turn the transfer switch to AUTO. After a time delay, the
regulator will return to an "IN" band condition.
4.
Turn the transfer switch to MANUAL.
5.
Run the tapchanger in the raise direction, at least until
the control is observed to go out of band "HIGH".
6.
Turn the transfer switch to AUTO. After a time delay, the
regulator will return to an "IN" band condition.
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.
REMOVING THE REGULATOR FROM SERVICE
Page 10
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 position. 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 regulators in the bank. The routine removal procedure is essentially the reverse of the procedure used to place the regulator
on the line.
WARNING
High pressure or mechanical failure due to improper bypass operation can cause death, severe injury or damage.
To prevent:
Bypass regulator only with regulator on neutral tap position.
Follow instructions:
1. Run the regulator under normal voltage source to the
neutral position, as revealed by the tap position indicator.
2. Confirm via the NeutraliteTM indicator that the regulator is on neutral. If the independent checks of the position indicator and NeutraliteTM indicator do not confirm the neutral position, bypassing must not be attempted. In such event, de-energize the system to remove the regulator from service.
3. After assuring that the regulator is on neutral, close
the bypass switch.
4. Open, sequentially, the load and source switches.
5. (a.) For a single phase or grounded wye connection,
make sure that the high voltage disconnect switches
are opened.
(b.) For a closed delta connection, be sure all regulators in the bank are bypasses and isolated.
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.
MAINTENANCE
Page 11
GENERAL INSTRUCTIONS
Failure to properly maintain the regulator can result in severe 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 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.
When powered, dangerous voltages are present in the equipment that can cause severe personal injury, death, and product 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 adjustments 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 regulator 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 bandwidth 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 continuously without damage
CAUTION
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.
WARNING
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.
MAINTENANCE
Page 12
PERIODIC INSPECTION
A sample of oil from the regulator should be subjected to
dielectric breakdown test, per ASTM D-877. It is recommended 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.
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.
The oxidation inhibitor in the oil will be depleted over a period 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.
To untank a JFR regulator, proceed as folllows:
1.
Remove the regulator from service as described on
Page 7.
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 three mounting bolts holding the control
box onto the main tank.
5.
Loosen all cover bolts and turn outward 180 degrees.
6.
The regulator can now be pulled from the main tank
by the cover lifting eyes.
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 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 service at low contact temperatures, but much further deterioration will probably result in decreased spring pressure and
possibly faulty operation. Therefore, the contact should definitely be replaced. (See Figure in next column.)
•
SEALED REGULATORS WITH
PRESSURE RELIEF VALVE
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.
• FANS
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 medium 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 recommended that this lubrication be placed on a yearly schedule.
It is often possible to determine by inspection whether lubrication is required.
SPECIAL FEATURES
Page 13
POLARIZED DISCONNECT SWITCH
(JACK PLUG) AND HINGED
CONTROL PANEL
The Accu/StatTM 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 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.
REMOTE MOUNTING
OF CONTROL
EQUIPMENT
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 conductors.
VARI-AMPTM POSITION INDICATOR
The Vari-AmpTM 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 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 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.
SPECIAL FEATURES

Catalog
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 derating
of voltage.

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