Transformer application
Depending on the transformer application, information in addition to the details
provided in the "Transformer data" order details sheet is required to produce an
optimum on-load tap-changer or off-circuit tap-changer. This additional information can be entered under "Remarks" or provided as an attachment. Such
data is listed below for particular applications:
a) Network application
No additional data is needed for network applications.
b) Generator application
MR on-load tap-changers satisfy the requirements of IEC 60076-1 (5 %
overexcitation) and ANSI IEEE C57.12 (10 % overexcitation). If greater
overexcitation is possible, this should be stated.
c) Phase shifter
For phase shifter transformers, a sketch of the circuit and details of all relative short-circuit voltages (in relation to mains power), the overload factor
required, the phase angle (under rated load and when idling) and all turn
numbers are needed.
d) HVDC transmission
The following details are needed for HVDC transmission applications (both
for rectifier operations with thyristors and IGBTs):
Rate of current rise di/dt in current zero crossing, with reference to a
transformer arm
Overload factor
The winding arrangement should be attached
 In the case of rectifier operations with two 2-winder transformers, the
winding arrangements of both transformers should be attached.

2 General data relating to the inquiry or order
If uninterrupted tap-changer actuation above and beyond one half
switching cycle (in the sense of IEC 60214-1, on-load tap-changer
movement from one end of its regulating range to the other) is expected,
the following information should be provided:
 The maximum transformer oil temperature assumed (top oil layer)
 Definition of specific switching frequency requirement (possibly in
the form of a separate table):
-
How many tap changes should be possible in what time and with
pauses of what length between them? How often must it be
possible for the stated switching sequence to be repeated after
one cycle?
-
The assumed average current through the on-load tap-changer
during a switching sequence (overloads may have to be taken
into account)
-
The assumed average step voltage (if not constant over the regulating range) during a switching sequence
If a cooling measure is needed for the on-load tap-changer oil (oil radiator with free air convention), state whether the maximum ambient
temperature is 40°C according to IEC 60076-1 or deviates from this
e) Electrolysis and rectifier transformer application
For electrolysis and rectifier transformer applications, a sketch of the circuit
should be attached along with details of all turn numbers; in the case of
variable induction, point 3.2.5 should be noted and in the case of multiple
coarse tap connection, point 3.2.10.
f)
Furnace application
In the event of furnace applications, state whether you are working with a
ladle furnace operation (LF) or electric arc furnace operation (EAF). In the
case of variable induction, points 3.2.3 and 3.2.5 should be taken into account. An extra table showing voltage, current and turn numbers for each
position should also be attached for intermediate circuit operations. The
overload factor should be stated if it is greater than 2.5.

compensation reactor. An extra table showing voltage, current, impedance
and turn numbers for each position should also be attached.
With a standard reactor, the overload factor should be stated if it is greater
than 2.5.
If an on-load tap-changer with open neutral point is to be used with a
compensation reactor (only possible with OILTAP®M), this should be
stated on the "On-load tap-changer data" order details sheet under "Remarks".
h) Railway application
Details of overload (loading class according to EN50329 or a load profile)
and short-circuit behavior (both the short-circuit current and the frequency
of short-circuits per month) are needed for rail transformers.
i)
Test transformers
The types of tests for which the transformer is used are decisive to selecting
the on-load tap-changer or off-circuit tap-changer for test transformers. You
should always state which frequencies arise (less than 50 Hz or more than
60 Hz).
For test transformers which are to be used with short-circuit tests, in addition to details of the short-circuit current, details of the frequency of
short-circuits per month are also important.

Number of steps and basic connection diagram
The tap selector can be adapted to the number of steps required and the tap
winding circuit. The corresponding basic connection diagrams differ in terms of
tap selector division (10...18), number of operating positions, number of
mid-positions and change-over selector version. The basic connection diagram
is named as per Figure 26.
The adjustment position is the position in which the on-load tap-changer is
supplied. The on-load tap-changer must be in the adjustment position during
maintenance work (removal or fitting of on-load tap-changer insert). Please
refer to the respective operating/maintenance instructions for more details. The
adjustment position is explicitly stated in each of the on-load tap-changer's
detailed connection diagrams.
The mid-position is the position in which the "K" contact is switched for the
reversing change-over selector or coarse tapping model. The mid-position is
also generally the adjustment position (see detailed connection diagram for
on-load tap-changer).
1 mid-position: With 1 mid-position, there are no positions with the same voltage either upstream or downstream of the "K" contact.
3 mid-positions: With 3 mid-positions, there is no change in voltage upstream
and downstream of the "K" contact.
Note: Bridged contacts are not considered the mid-position

MR only provides one head variant for on-load tap-changer type VACUTAP®
VV and this can be rotated in 15° steps (upper part of head can be twisted in
relation to lower part of head; on-load tap-changer cover cannot be twisted in
relation to upper part of head). Exception: upper part of head cannot be twisted
in relation to lower part of head for the variant with an oil suction pipe in the
on-load tap-changer!
On-load tap-changer OILTAP® V is also only available in one head variant.
You can select the appropriate head variant for on-load tap-changer types
VACUTAP® VR and VM as well as OILTAP® R, RM, M and MS. We offer 3

The RS 2001 protective relay is attached as described in the related MR operating instructions for the protective relay (BA 59/07).
Pipe connection S for suction pipe
Pipe connection S is provided with a vent screw. If no feed pipe of a stationary
oil filter unit is connected here, a pipe must be connected which ends with a
drain valve at the side of the transformer tank at operating height.
Pipe connection Q (oil filter unit or cable duct for tap-change supervisory
control)
This pipe connection serves as the connection of the oil return pipe of a stationary oil filter unit. If no oil filter unit is connected, a blank cover is mounted
instead of the pipe connection.
An optional tap-change supervisory control is also connected to pipe connection Q. The swivel range of this pipe connection is restricted. Figure 45 shows
the difference between a normal pipe connection and one for the tap-change
supervisory control.
Pipe connection E2
This connection is sealed using a blank cover as standard. It runs into the

1203/1503, R I 2002, R I 3003 and for VACUTAP® VR I 1001, VR I 1301).
Parallel bridges on the tap selector connection contacts are then mandatory if
the tap winding has been wound in two or more branches and each of these
branch taps is connected to the contacts of the tap selector.
This measure prevents the following:
o Introduction of circulating currents into the current paths of tap selector and
diverter switch
o Commutating arc on movable tap selector contact bridges

DEETAP® DU off-circuit tap-changer type
(For more detailed information, see technical data TD 266/04)
Off-circuit tap-changers are used for voltage regulation of oil-immersed transformers. In contrast to on-load tap-changers, the required winding taps must be
set with the transformer switched off on the high voltage and low voltage side.
Off-circuit tap-changers are designed on the principle of a modular system allowing maximum rated through-currents of 200 A, 400 A 600 A, 800 A and 1000
A per current path. Off-circuit tap-changers DEETAP® DU are available with up
to 17 operating positions.
Switching concept
The off-circuit tap-changer is changed over from one operating position to the
next by rotating an insulating drive shaft. The DEETAP® DU off-circuit
tap-changer is activated via a step-by-step gear with a hand wheel or operating
wrench or with manual drive TAPMOTION® DD or motor-drive unit
TAPMOTION® ED.
The scope of supply of the DEETAP® DU includes the following basic circuits
(for sketches of circuits, see 6.6):
Linear off-circuit tap-changer for neutral and delta connection
Single-bridging off-circuit tap-changer
Double-bridging off-circuit tap-changer
Series-parallel off-circuit tap-changer
Star-delta off-circuit tap-changer

c) Bell-type tank installation
For installation in a transformer with bell-type tank, the off-circuit tap-changer
has to be mounted on a special supporting structure that enables temporary
suspension of the off-circuit tap-changer from the supporting flange. The
bell-type tank flange has drilled holes so that it can easily be affixed to the
supporting structure. The off-circuit tap-changer is first lifted into the supporting
structure, fixed in this provisional mounting position and connected to the tap
winding without a drive head. A bell-type tank flange with 18mm holes is supplied as standard. Other variants are available on request.

COMTAP® ARS
(For more detailed information, see technical data TD 1889046/03 DE)
The COMTAP® ARS is used to switch over a winding during transformer operation. The COMTAP® ARS basically has two operating positions. The
COMTAP® ARS is changed over from one operating position to the next by
rotating an insulating drive shaft. This insulating drive shaft is operated via a
60° control gear that is driven via a TAPMOTION® ED motor-drive unit.
Changing an operating position requires a 120° tap change of the insulating
drive shaft. Two motor drive operations (double tap change) are therefore
needed for a COMTAP® ARS operation. The COMTAP® ARS contact system
has a contact circle diameter of 850 mm. During a COMTAP® ARS operation
the through-current is commutated from one current path to another current
path with the same potential. The contact system is equipped with special
contacts for this purpose. The COMTAP® ARS can be used for different applications in combination with an on-load tap-changer. The COMTAP® ARS is
primarily used to reverse the polarity of the regulating voltage in applications
with large regulating ranges (e.g. phase shifter transformers).

The oil filter unit OF100 is used for cleaning or for cleaning and drying the

Oil cooling unit
(For detailed information, see operating instructions BA 2103288/00 DE)
When on-load tap-changers with very high switching frequencies are being
operated, Maschinenfabrik Reinhausen GmbH can require oil cooling for the
on-load tap-changers due to the temperature calculations. In this case, the OF
100 oil filter unit is used as a pump for the oil cooling unit of the on-load
tap-changer oil.
Cleaning and drying the oil with the combination filter cartridge also offers the
added advantage of longer maintenance intervals for the OILTAP® M and
OILTAP® R (see operating instructions BA 018 for the OF 100 oil filter unit).
Note: Only the fields marked with a * need completing for the control version in

Filter type
The oil filter unit is used for cleaning or for cleaning and drying the tap-changer
oil in on-load tap-changers. It can be equipped with a choice of a paper filter (for
cleaning) or a combination filter cartridge (for cleaning and drying).
a) Cleaning on-load tap-changer oil with paper filter
When on-load tap-changers are used in industrial transformers under extremely onerous conditions (high number of switching operations, consistently
at full load and high frequent overloads) arcing will relatively soon cause contamination of the on-load tap-changer oil. This applies, for example, to on-load
tap-changers incorporated into transformers on furnace or electrolytic plants.
These service conditions can be met by an oil filter unit with a paper filter
cartridge. The paper filter insert allows the on-load tap-changer oil to be
cleaned of solid particles. The number of inspections requiring oil changes is
reduced compared with the short intervals required in other cases.

9 Oil filter unit OF100
b) Cleaning and drying the on-load tap-changer oil via combination filter
cartridge
When the on-load tap-changer is installed in areas where humidity is extremely
high and the temperature in the oil conservator usually falls below the dew point
every day, an increased water content in the on-load tap-changer oil and an
accumulation of water in the carbon deposited on the insulating materials can
occur. This will deteriorate the insulating properties of the on-load tap-changer.
The combination filter cartridgenot only filters contaminating solid particles
from the on-load tap-changer oil but also reduces the water content to a residual amount of < 10 ppm. The oil monitoring required can be reduced and oil
treatment during maintenance may not be required. The combined filter cartridge is equipped with a paper filter on the outside (filter fineness ca. 9 mm)
and filled with a drying agent on the inside (granules approx. 4 kg).
9.2.3
Replacement filter
Additional filter inserts can be ordered here.
9.2.4
Thermal switch (signal emission TMedium > 25 °C)
For a certain time (oil temperature <25°C), the thermal switch suppresses the
signal from the oil filter unit's overpressure monitor.
Reason: If the oil temperature falls (<25°C), the oil viscosity falls too. This is
suppressed by the thermal switch so that the overpressure signal doesn't occur
prematurely.
9.2.5
Continuous operation below 0° Celsius (thermostat for operation
TMedium < 0 °C)
Temperature sensor (model for cold weather operation)
The low temperature model is recommended for regions where temperatures
under 5 °C are to be expected in the oil filter unit or in the pipes during the
winter months. This is the reason a temperature sensor is used which lets the
unit run until the oil temperature in the system has risen above the preset value
of +5°C (adjustable temperature range: 0 °-120 °C).

In the case of transformers whose transmission ratio is changed by on-load
tap-changers with remote-controlled motor-drive units, the on-load tap-changer
operating positions must be displayed in the control room. This can be done
using tap position indicator instruments.

Signaling device
Remote tap position indicator/indicator instrument (analog) for signal via resistor contact series
(For a detailed description, see operating instructions 2220061/01)
In the position indicator module, depending on the tap position a modified resistance value is provided at the position indicator instrument's input. The indicator instrument operates with a total resistance range of 60 - 2,700 ohms.
Resistance model position indicator equipment is needed in the motor-drive
unit. The resistor contact series (e.g. 10 ohms per step) must be produced to
match the number of tap positions desired. The resistance module is connected
to the indicator instrument and/or mains adaptor with bridge circuit via a signal
line.
Remote tap position indicator/indicator instrument (analog) for signal via
measuring transducer (4...20 mA)
(For a detailed description, see operating instructions 2220015/01)
Note: A maximum of 19 tap positions is possible
In the position indicator module, depending on the tap position a modified resistance value is provided at the measuring transducer's input in the motor-drive unit. This measuring transducer converts the resistance input signal
into a constant current signal (e.g. 4...20 mA). The measuring transducer's
input signal is basically defined as 10 ohms per step, the output signal can vary
but is 4...20 mA as standard. The indicator instrument is adapted to the output
signal and therefore indicates the motor-drive unit's position depending on the
constant current signal.
A measuring transducer is also provided in the motor-drive unit to convert the
resistance signal into a constant current signal (4...20 mA).

Lamp panel
Function
The lamp panel is used for the display of the current operating position of the
on-load tap-changer and the manual change of the operating position from any
location. The distance between this location and the motor-drive unit is limited
to the voltage drop of the line and depends on the voltage applied on the motor-drive unit. The number of displayed operating positions depends on whether
a continuous or decade contact series is connected to the lamp panel.

Type of contact series
Continuous contact series
In the case of a system with a continuous contact series, a terminal of the position indicator module is assigned to each position of the on-load tap-changer.
Only this terminal leads to a signal in the intended position, no other terminals
do this. Since 28 lighting elements are provided on the lamp panel, a maximum
of 28 positions can be displayed with one continuous contact series connected
to a lamp panel.
Decade contact series
If more than 28 positions are to be displayed, a decade contact series must be
connected to the lamp panel. In the process, the zero and first power are displayed separately. 10 terminals are assigned the values 0 to 9 and 10 terminals
the values 00 to 90. In position 19, for example, the terminal with a value of 9
and the terminal with a value of 10 conduct signals.

Code
Inscriptions are provided according to the code used (BCD, DUAL, GRAY
code) (see Table 20). The BCD code according to the ANSI standard displays
the values "L; N; R" in place of "+/-".
The display is available with code converters for these codes and is prepared
for other codes.
The unit can be put to individual use thanks to its modular structure (signal
transmitter not dependent on code) and the use of a mains unit that covers the
entire voltage range (48...265 V DC/AC 50, 60 Hz).

Signaling device
The signals prepared are converted by a code converter integrated in the display module and displayed. The signal is also available in the control unit free
from potential for further digital processing (e.g. network control center).
Via diode matrix
The data is captured electrically at source, in this case at the motor-drive unit
(diode matrix), transmitted over long distances and prepared anywhere, usually
in the control room.
The function of the signal transmitter is not dependent on the coding of the
digital signals.
Via resistor contact series
The analog measured value is captured electrically at source, in this case at the
motor-drive unit (resistance value) using a resistor contact series (10 ohms per
step). This changeable resistance value is sent to the A/D converter input. The
measured value is digitalized and output in code at the digital output.
This signal is transmitted over long distances and prepared anywhere, usually
in the control room.
The function of the A/D converter is not dependent on the coding of the digital
signals.

Connecting cable
The scope of supply includes three different lengths of connecting cable between the signal converter and 7-segment display.
