DAMAGE IN SHIPMENT 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 ca rrier
making the delivery and make appropriate notation on the
freight bill. Any damage or shortage that is not noted on the
freight bill becomes the recipients responsibility. A claim
should be made immediately with the carrier. Please also
notify your Siemens representative as soon as possible.

Assure that the control compartment enclosure is tightly
closed, and regulator tank is sealed.

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.

• 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.

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 #2 to 477 MCM
301A to 668A #2 to 800 MCM
669A to 1200A 1.125- 12 UNF-2A
1201 A to 2000A 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.

Conductor Size Range
or Threaded Stud Size

ELECTRICAL CONSIDERATIONS

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

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

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

Will cause serious injury or death.
To prevent:

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.

• 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 th e cove r
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.

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 per ANSI C57.15.

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. 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 regul ator
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 term i na l b lock.

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

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

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 con trol 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
external source and observing the Neutralite

illuminated.

MAINTENANCE

Page 11

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.

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
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 w ill stall again st 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.

MAINTENANCE

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 per iod
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.

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)

To untank a JFR regulator, proceed as folllows:

1. Remove the regulator from service as described on

Page10.

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
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.

Oil-Lite sleeve bearings should be oiled at

POLARIZED DISCONNECT SWITCH VARI-AMP
(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 position. Th is 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.

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 runnin g 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 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 t hat
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.

SPECIAL FEATURES Page 15

FORCED AIR COOLING

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.

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 auto matica lly disconne cted
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.

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 li ve part o f
the regulator bushing.
