Function description of the voltage regulation
The TAPCON® 260 serves to keep constant the output voltage of a bank of
transformers with on-load tap-changers. The bank of transformers consists
of 3 single-phase transformers, each with an on-load tap-changer and mo-
tor-drive unit.
The TAPCON® 260 compares the measured voltage of the bank of trans-
formers (Uactual) with a defined reference voltage (Udesired). The difference be-
tween Uactual and Udesired is the control deviation (dU).
The TAPCON® 260 parameters can be optimally adjusted to the line voltage
response to achieve a balanced control response with a small number of
tap-change operations by the on-load tap-changer.
The following diagram shows an overview of voltage regulation.

Hardware
The individual assemblies are fitted in a standardized 19-inch plug-in hous-
ing. The front panels of the assemblies are secured to the plug-in housing at
the top and bottom. An IEC 60603-2 plug connector provides the electrical
connection.
The assemblies are connected to one another via a data bus and direct cur-
rent (DC) supply. This allows for an upgrade with additional plug-in modules
and extension cards at a later date.

WARNING
Electric shock
Risk of fatal injury due to connection mistakes
►
Ground the device with a protective conductor using the grounding
screw on the housing.
►
Note the phase difference of the secondary terminals for the current
transformer and voltage transformer.
►
Connect the output relays correctly to the motor-drive unit.
Supply the voltage via separators and ensure that current paths can be
short circuited. Fit the separator, clearly labeled, near the device's power
supply so that it is freely accessible. This will allow the device to be re-
placed with ease in the event of a defect.
Cable recommendation
Please note the following recommendation from Maschinenfabrik Reinhau-
sen when wiring the device.
Excessive line capacitance can prevent the relay contacts from breaking the
contact current. In control circuits operated with alternating current, take into
account the effect of the line capacitance of long control lines on the func-
tion of the relay contacts.

Information about laying fiber-optic cable
To ensure the smooth transfer of data via the fiber-optic cable, you must en-
sure that mechanical loads are avoided when laying the fiber-optic cable and
later on during operation.
Please note the following:
▪
Radii must not fall below the minimum permissible bend radii (do not
bend fiber-optic cable).
▪
The fiber-optic cables must not be over-stretched or crushed. Observe
the permissible load values.
▪
The fiber-optic cables must not be twisted.
▪
Be aware of sharp edges which could damage the fiber-optic cable's
coating when laying or could place mechanical loading on the coating
later on.
▪
Provide a sufficient cable reserve near distributor cabinets for example.
Lay the reserve such that the fiber-optic cable is neither bent nor twisted
when tightened.

Information about shielding the CAN bus
In order for the CAN bus to operate faultlessly, you have to connect the
shielding using one of the following variants. If you are not able to use any of
the variants detailed below, we recommend using fiber optic cables. Fiber
optic cables decouple the voltage regulators and are not sensitive to electro-
magnetic interferences (surge and burst).
NOTICE
Damage to the device
If you connect the CAN bus cable to devices with different potential, current
may flow over the shielding. This current may damage the device.
►
Connect the devices to a potential compensation rail to compensate for
potential.
►
If both devices have different potentials, only connect the CAN bus ca-
ble's shielding to one device.
Variant 1: The connected devices share the same potential
If the devices to be connected share the same potential, proceed as follows:
1.
Connect all devices to a potential compensation rail to compensate for
the potential.
2.
Connect CAN bus cable's shielding to all connected devices.

Checking parallel operation of several banks of transformers
This section describes how you can run the function test for parallel opera-
tion of several banks of transformers .
To obtain perfect functioning in parallel operation, the voltage regulator must
be commissioned in simplex mode. Make sure that the conditions below
have been fulfilled.
▪
All motor-drive units of the banks of transformers (ED1...ED3) are in the
same tap position.
▪
All devices are set to the same operating parameters for desired value,
circulating reactive current sensitivity and delay time T1.
▪
The circulating reactive current sensitivity on all devices must be set to
0 %.
▪
The circulating reactive current blocking parameter must be set to
20 %.
▪
You must undertake all settings in manual mode.
▪
Each device needs an individual address on the CAN bus.
Checking circulating reactive current sensitivity
This section describes how to run the function test for circulating reactive
current sensitivity.
1.
Adjust both transformers in simplex mode to the same actual voltage by
means of the on-load tap-changer.
ð
When both devices are in a state of equilibrium, then the value of
the control deviation dV [%] is smaller than the set bandwidth. You
can see this in the main screen if the mark for the measured volt-
age Uactual is within the bandwidth.
2.
Connect the transformers in parallel and enable the parallel control.
ð
The two devices must still be in a state of equilibrium.
ð
The Parallel operation LED on the front panel is illuminated.

3.
On one of the two transformers, raise the tap position of the on-load tap-
changer by one setting; on the second transformer, lower the tap posi-
tion of the on-load tap-changer by one setting.
ð
The two devices must still be in a state of equilibrium.
4.
Adjust the circulating reactive current sensitivity until the result dis-
played exceeds the set value for the bandwidth by approx. 0.2 % to
0.3 %.

The value for the result changes in the help text in the last line of
the display.
5.
Set the value given in the previous step for all devices in parallel opera-
tion.
6.
Press
to select auto mode for both devices.
ð
The devices return the on-load tap-changer units to the original tap
positions.
ð
The function test for circulating reactive current sensitivity is complete.
If the earlier tap positions are not reached, increase the value of the circulat-
ing reactive current sensitivity [► 93] parameter.
If one of the two on-load tap-changer units switches one or more tap posi-
tions higher and the other switches the same amount lower, you need to re-
duce the value of the circulating reactive current sensitivity [► 93] parame-
ter.
After you have set the circulating reactive current sensitivity parameter,
continue with the circulating reactive current blocking function test described
in the next section.
Checking circulating reactive current blocking

current blocking.
1.
Press
on one device to select manual mode.
2.
Using manual control, adjust the relevant motor-drive unit upwards by
the maximum permitted tap difference in operating positions between
the parallel operating transformers (for example by 1 - 2 steps).
When setting the circulating reactive current blocking in the following proc-
ess step, wait approx. 2 - 3 seconds between the individual steps.
3.
Set the parallel operation method parameter to circulating reactive
current.
5.3.3.2

4.
The circulating reactive current blocking parameter should be re-
duced [► 93] from the set value of 20 % in steps of 1 % until the Par-
allel operation error: circulating reactive current limit exceeded is dis-
played.
ð
The Parallel operation LED lights up when the circulating reactive
current blocking limit is reached.
ð
Any further regulation is blocked.
5.
After the set delay time for the parallel operation error message (time
can be adjusted [► 95]), the signaling relay UC-X1:1/UC-X1:2 (default
setting) is activated.
6.
Increase the circulating reactive current blocking parameter again
until the message Parallel operation error: circulating reactive current
limit exceeded disappears.
7.
Press
to select auto mode.
ð
The motor-drive unit automatically returns to the original operating
position.
8.
Set the value determined for the circulating reactive current blocking
on the devices in parallel operation as well.
If one or all devices indicate Parallel operation error: circulating reactive cur-
rent limit exceeded although the control inputs are correctly connected for
all the devices, then all the devices block.
This could be due to various causes. Further information is given in the
chapter Troubleshooting [► 139].
ð
The function test for circulating reactive current blocking is complete.
Checking tap synchronization method
This section describes how to run the function test for tap synchronization
(master/follower). If instances arise where a follower switches in the opposite
direction to the master step change, then the setting for the tapping direction
[► 61] parameter on the follower must be changed from Default to Swap-
ped.
NOTICE
Damage resulting from formation of circulating reactive current
If the parameters are not set correctly, damage may result from the forma-
tion of circulating reactive current and the resulting overload of transmission
lines and transformers.
►

►
Set device parameters in accordance with transformer configuration.
Before starting the function test, you must carry out the following steps:
1.
Assign the master function to one device.
2.

Setting motor runtime monitoring
You can use this motor runtime parameter to set the motor runtime. The mo-
tor-drive unit's runtime can also be monitored by the device. This function is
used to identify motor-drive unit malfunctions during the tap-change opera-
tion and to trigger any actions needed.
The motor-drive unit issues the Motor-drive unit running signal during the
tap-change operation. This signal is present until the tap-change operation is
complete. The device compares the duration of this signal with the set motor
runtime. If the set motor runtime is exceeded, the device triggers the follow-
ing actions:
1.
Motor runtime monitoring message is issued
2.
Continuous signal via output relay Motor-drive unit runtime exceeded
(optional)
3.
Pulse signal via Trigger motor protective switch output relay (optional)
To use runtime monitoring, you need to correctly wire the corresponding
control input and parameterize to Motor running. The motor runtime must al-
so be set.
If you want to monitor the motor runtime, the device and motor-drive unit
must be connected and parameterized as shown below.

Behavior only with delay time T1
If the measured voltage Uactual
is within the set bandwidth
, no control
commands are issued to the motor-drive unit for the tap-change operation.
Control commands will also not be issued to the motor-drive unit if the meas-
ured voltage returns to the tolerance bandwidth
within the set delay time
T1
. However, if the measured voltage deviates from the set bandwidth for
a long period
, a tap-change command
occurs after expiration of the
set delay time T1. The on-load tap-changer carries out a tap-change in a
raise or lower direction to return to the tolerance bandwidth.

If the measured voltage Uactual
deviates from the set bandwidth for a long
period
, a control impulse is output to the motor-drive unit after the set de-
lay time T1
. If the measured voltage Uactual is still outside the bandwidth,
delay time T2
starts once delay time T1 is complete. Once delay time T2
is complete, a control impulse is again output to the motor-drive unit for the
tap change
to return to the tolerance bandwidth.

You can use this parameter to set up to 3 desired voltage values URef. The
desired voltage value is specified as a fixed value. The desired value 1 is the
default desired value. Desired values 2 and 3 are activated if there is a con-
tinuous signal at factory-preset control inputs IO-X1:31 or IO-X1:33 provided
you have programmed these previously. If there is a signal at several control
inputs at the same time, desired value 2 is activated.

Setting control response T1
The control response T1 can be set to linear or integral.
With linear control response, the device responds with a constant delay time
regardless of the control deviation.
With integral control response, the device responds with a variable delay
time depending on the control deviation. The greater the control deviation
(ΔV) in relation to the set bandwidth (B), the shorter the delay time. The de-
lay time can therefore be reduced down to 1 second. This means that the
device responds faster to large voltage changes in the grid. Regulation accu-
racy improves as a result but the frequency of tap-changes increases too.

Setting delay time T2
With this parameter, you can set delay time T2. Delay time T2 is used to
compensate for large control deviations faster.
The delay time T2 only takes effect if more than one tap-change operation is
required to return the voltage to within the set bandwidth. The first output
pulse occurs after the set delay time T1. After the set tap-change delay time
T2 has elapsed, additional pulses occur in order to correct the existing con-
trol deviation.
The following requirements must be noted to set delay time T2:
▪
The delay time T2 must be greater than the switching pulse time.
▪
The delay time T2 must be greater than the maximum operating time of
the motor-drive unit.
▪
The delay time T2 must be less than the value set for delay time T1.

cut.
If the measured voltage Uactual
falls below the set limit value
, the red
LED U< lights up . The switching pulses to the motor-drive unit are blocked
at the same time provided you have activated the blocking undervoltage U<
parameter. Once the set signaling delay time [► 71]
has passed, the
signaling relay activates. The Undervoltage U<
message appears in the
display. The message is reset as soon as the measured voltage Uactual again
exceeds the limit value for undervoltage
. If the measured voltage Uactual
falls below 30 V
(for example when the transformer is switched off), the
Undervoltage message is also displayed. You can however suppress

Compensation
You can use the "Compensation" function to compensate for the load-de-
pendent voltage drop between the transformer and consumer. The device
provides 2 methods of compensation for this purpose:
▪
R&X compensation (line drop compensation)
▪
Z compensation
R&X compensation
R&X compensation (LDC) requires exact cable data. Line voltage drops can
be compensated very accurately using LDC.
To set R&X compensation correctly, you need to calculate the ohmic and in-
ductive voltage drop in V with reference to the secondary side of the voltage
transformer. You also need to correctly set the transformer circuit used.

Z compensation
To keep the voltage constant for the consumer, you can use Z compensation
to activate a current-dependent increase in voltage. You can also define a
limit value to avoid excess voltage on the transformer.
Figure 49: Z compensation
To use Z compensation, you need to calculate the increase in voltage (ΔU)
taking the current into account. Use the following formula for this purpose:
∆U
Voltage increase
I
Load current in A
UTr
Transformer voltage with
current I
IN
Nominal current of current-
transformer connection in A
(0.2 A; 1 A; 5 A )
ULoad

I = 100 A

For the check, the measured voltage of the device
is transmitted to the
device
via a second separate measurement input and vice versa. The
calculated measured voltage is compared with the original measured values
via the CAN bus. If the measured values deviate, the Measured value error
message is issued.
When checking the limit values, one device transmits a measured voltage to
the other via the second separate measurement input. You can set the fol-
lowing limit values for this measured value:
▪
Separate desired value [► 80]
▪
Undervoltage limit value [► 81]
▪
Overvoltage limit value [► 82]
As soon as one of the set limit values is exceeded, once the set delay time
for the error message [► 83] has lapsed, the Measured value error mes-
sage is output. If wired accordingly, relay contacts can block the raise/lower
pulse to the motor-drive unit. Regulation of individual devices is not affected
by limit value monitoring.

Parallel operation of several banks of transformers
In the Parallel operation menu item, you can set the parameters needed for
parallel operation of banks of transformers. Parallel operation of banks of
transformers is used to increase the throughput capacity or short-circuit ca-
pacity in one place.
Compliance with the following general conditions is required for operating
banks of transformers in parallel:
▪
Identical rated voltage
▪
Transformer power ratio (< 3 : 1)
▪
Maximum deviation of short-circuit voltages (UK) for transformers con-
nected in parallel < 10 %
▪
Same number of switching groups
You can control up to 16 banks of transformers connected in parallel in one
or 2 groups without detecting the system topology. Information is swapped
between the voltage regulators operating in parallel using the CAN bus. Par-
allel operation is activated using one of 2 status inputs or the control system.
Parallel control can take one of two forms:
▪
Parallel operation following the "Circulating reactive current minimiza-
tion" principle
▪
Parallel operation following the "Tap synchronization" (master/follower)
principle
The following sections describe how you can set the parameters.
Assigning CAN bus address
You can use this parameter to assign a CAN bus address to the device. So
that all devices can communicate using the CAN bus, each device requires a
unique identifier. Addresses can be set from 1 to 16. If the value is set to 0,
then no communication takes place.

▪
Circulating reactive current minimization
▪
Tap synchronization (master/follower)
You must select the same parallel operation method for all voltage regula-
tors operating in parallel.
The following sections describe how you can set the parameters for a paral-
lel operation method.
Setting circulating reactive current method
When the circulating reactive current parallel operation method is select-
ed, then parallel operation is carried out using the circulating reactive current
minimization method. The circulating reactive current is calculated from the
transformer currents and their phase angles. A voltage proportional to the
circulating reactive current is added to the independently operating voltage
regulators as a correction for the measurement voltage. This voltage correc-
tion can be reduced or increased using the circulating reactive current sensi-
tivity setting.
The circulating reactive current method is suited to transformers connected
in parallel with a similar nominal output and short-circuit voltage VK and to
vector groups with the same and different step voltages. This does not re-
quire any information about the tap position.
To set the circulating reactive current parallel operation method, proceed

When using the circulating reactive current parallel operation method, you
have to set the parameters for the circulating reactive current sensitivity
and circulating reactive current blocking.
Setting circulating reactive current sensitivity
The circulating reactive current sensitivity is a measure of its effect on the
behavior of the voltage regulator. At a setting of 0 % no effect is present.
With circulating reactive current relating to the rated current of the current
transformer, if you set the value to 10 % for example, this would cause the
voltage in the voltage regulator to be corrected by 10 %. This correction to
the voltage can be increased or decreased with this setting to attain the opti-
mum value.
As soon as you change the circulating reactive current sensitivity value, the
value for the result changes in the help text in the display.

active current exceeds the set limit value, then the following event is activat-

Setting tap synchronization
With the tap synchronization method, you need to designate one voltage
regulator as the master and all others as followers. The master handles volt-
age regulation and transmits its latest tap positions to all followers via the
CAN bus. The followers compare the tap position received with their own tap
position. If the set permissible tap difference between the tap position re-
ceived and their own position is exceeded, the followers switch to the tap po-
sition received from the master. This ensures that the transformers operating
in parallel are always in the same tap position.
For the tap synchronization method, you can select the following options:
Option
Description
Master
The voltage regulator is designated as the master.
Follower
The voltage regulator is designated as the follower.
Sync.auto
Automatic assignment of master or follower.
If no master is detected, the voltage regulator with the
lowest CAN bus address is automatically designated
as the master. All other voltage regulators are desig-
nated as followers.
Table 22: Tap synchronization method
In parallel operation, an individual CAN bus address must be assigned to
each voltage regulator. Up to 16 CAN participants are supported.

Selecting parallel operation control
As an option, the device can be fitted with a plug-in card for parallel opera-
tion with an existing parallel operation control unit when extending existing
systems. You can connect the following parallel operation control units:
▪
SKB 30E
▪
VC 100E-PM/PC
The settings required for parallel control must be undertaken in accordance
with the relevant valid operating instructions of the parallel operation control
unit.
If you do not have a parallel control unit, in the SKB parallel operation dis-
play you must select the Off selection. The possible selections are described
in more detail in the table below.

Setting delay time for parallel operation error messages
You can use this parameter to set the delay time for a parallel operation er-
ror message so that brief fault messages are not received if the motor-drive
units involved in the parallel operation have different runtimes. Once the set
delay time has elapsed, the event is issued at the output relay. Automatic
regulation is blocked and the on-load tap-changers can only be adjusted in
manual mode.
To set the delay time for the parallel operation error message, proceed as
follows:

Analog tap position capture (optional)
For the analog tap position capture, you must assign the lowest tap position
to the analog input for the minimum measured value and the highest tap po-
sition for the maximum measured value.
The device is configured at the factory according to the order. However,
should modifications be necessary, note the following sections.
The analog input card is used to record the tap position of an analog signal
transmitter. Depending on device configuration, you can capture the follow-
ing signals:
AD card
AD8 card
Resistor contact series
50...2,000 ohms
not possible
Injected current
0/4...20 mA
0/4...20 mA

Setting lower limit value
You can use these parameters to set the lower limit value for the tap posi-
tion . To do this, you must set the lower value of the signal range and the
linked lowest tap position.
You can undertake the settings for each input on the analog input card.
