4 Packaging, transport and storage
4 Packaging, transport and storage
4.1
Packaging
The products are sometimes supplied in a sealed packaging and sometimes in a dry state depending on requirements.
A sealed packaging surrounds the packaged goods on all sides with plastic foil. Products that have also been dried are identified by a yellow label on the sealed packaging.
The information in the following sections should be applied as appropriate.
4.1.1
Purpose
The packaging is designed to protect the packaged goods during transport, loading and unloading as well as periods of storage in such a way that no
(detrimental) changes occur. The packaging must protect the goods against permitted transport stresses such as vibration, knocks and moisture (rain, snow, condensation).
The packaging also prevents the packaged goods from moving impermissibly within the packaging. The packaged goods must be prepared for shipment before actually being packed so that the goods can be transported safely, economically and in accordance with regulations.
4.1.2
Suitability, structure and production
The goods are packaged in a sturdy cardboard box. This ensures that the shipment is secure when in the intended transportation position and that none of its parts touch the loading surface of the means of transport or touch the ground after unloading.
The box is designed for a maximum load of 10 kg.
Inlays inside the box stabilize the goods, preventing impermissible changes of position, and protect them from vibration.
4.1.3
Markings
The packaging bears a signature with instructions for safe transport and correct storage. The following symbols apply to the shipment of non-hazardous goods. Adherence to these symbols is mandatory.

4.2
Transportation, receipt and handling of shipments
In addition to oscillation stress, jolts must also be expected during transportation. In order to prevent possible damage, avoid dropping, tipping, knocking over and colliding with the product.
If a crate tips over, falls from a certain height (e.g. when slings tear) or is subject to an unbroken fall, damage must be expected regardless of the weight.
Every delivered shipment must be checked for the following by the recipient before acceptance (acknowledgment of receipt):
▪ Completeness based on the delivery slip
▪ External damage of any type
The checks must take place after unloading when the crate or transport container can be accessed from all sides.
Visible damage If external transport damage is detected on receipt of the shipment, proceed as follows:
▪ Immediately record the transport damage found in the shipping documents and have this countersigned by the carrier.
▪ In the event of severe damage, total loss or high damage costs, immediately notify the sales department at Maschinenfabrik Reinhausen and the relevant insurance company.
▪ After identifying damage, do not modify the condition of the shipment further and retain the packaging material until an inspection decision has been made by the transport company or the insurance company.
▪ Record the details of the damage immediately onsite together with the carrier involved. This is essential for any claim for damages!
▪ If possible, photograph damage to packaging and packaged goods. This also applies to signs of corrosion on the packaged goods due to moisture inside the packaging (rain, snow, condensation).
▪ Be absolutely sure to also check the sealed packaging.
Maschinenfabrik Reinhausen GmbH 2018 297/07 EN TAPCON® 250 29
4 Packaging, transport and storage
Hidden damage When damages are not determined until unpacking after receipt of the shipment (hidden damage), proceed as follows:
▪ Make the party responsible for the damage liable as soon as possible by telephone and in writing, and prepare a damage report.
▪ Observe the time periods applicable to such actions in the respective country. Inquire about these in good time.
With hidden damage, it is very hard to make the transportation company (or other responsible party) liable. Any insurance claims for such damages can only be successful if relevant provisions are expressly included in the insurance terms and conditions.
4.3
Storage of shipments
When selecting and setting up the storage location, ensure the following:
▪ Protect stored goods against moisture (flooding, water from melting snow and ice), dirt, pests such as rats, mice, termites and so on, and against unauthorized access.
▪ Store the crates on timber beams and planks as a protection against rising damp and for better ventilation.
▪ Ensure sufficient carrying capacity of the ground.
▪ Keep entrance paths free.
▪ Check stored goods at regular intervals. Also take appropriate action after storms, heavy rain or snow and so on.

5.2.2.4
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. Fiberoptic cables decouple the devices and are not sensitive to electromagnetic interference (surge and burst).
Damage to the device!
If you connect the CAN bus cable to devices with different potentials, current may flow across the shielding. This current may damage the device.
► Connect the devices to a potential equalization rail to equalize the potential.
► If both devices have different potentials, only connect the CAN bus cable 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 equalization rail to equalize the potential.
2.
Connect the CAN bus cable shielding to all connected devices.
Variant 2: The connected devices have different potentials
Note that the shielding is less effective with this variant.
If the devices to be connected have different potentials, proceed as follows:
► Connect the CAN bus cable shielding to just one device.
5.2.3
Information about laying fiber-optic cable
To ensure the smooth transfer of data via the fiber-optic cable, you must ensure that mechanical loads are avoided when laying the fiber-optic cable and later on during operation. Also observe the information from the manufacturer of the fiber-optic cable and the following instructions:
▪ 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.
36 TAPCON® 250 297/07 EN Maschinenfabrik Reinhausen GmbH 2018
5 Mounting
▪ Be aware of sharp edges because they can damage the fiber-optic cable's coating during laying or can place mechanical loads on the coating later on.
▪ Provide a sufficient cable reserve near distributor cabinets. Lay the reserve such that the fiber-optic cable is neither bent nor twisted when tightened.
5.2.4
Connecting cables to the system periphery
To obtain a better overview when connecting cables, only use as many leads as necessary.
To connect cables to the system periphery, proceed as follows:
ü Use only the specified cables for wiring. Note the cable recommendation.
► Connect the lines to be wired to the device to the system periphery as shown in the connection diagrams supplied.

Setting motor runtime monitoring
Behavior
You can use this motor runtime parameter to set the motor runtime. The motor-drive unit's runtime can be monitored by the device. This function is used to identify motor-drive unit malfunctions during the tap-change operation 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 following 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)
Parameterizing control input
To use runtime monitoring, you need to correctly wire the corresponding control input and parameterize to Motor running . The motor runtime must also be set.

All of the parameters required for the regulation function are described in this section. For voltage regulation, you can set the following parameters:
▪ Desired values 1…4
▪ Bandwidth
▪ Delay time T1
▪ Control response T1
▪ Delay time T2
For voltage regulation, you can set delay time T1 and also delay time T2.
The following sections describe how the regulation function responds in both cases:
Behavior only with delay time T1
If the measured voltage U actual
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 measured voltage returns to the tolerance bandwidth within the set delay time
T1 . However, if the measured voltage deviates from the set bandwidth for
66 TAPCON® 250 297/07 EN Maschinenfabrik Reinhausen GmbH 2018

Ensure that you set a lower value in the "Delay time T2" parameter than in the "Delay time T1" parameter.
If the measured voltage U actual
deviates from the set bandwidth for a long period , a control impulse is output to the motor-drive unit after the set delay time T1 . If the measured voltage U actual

The following sections describe how you determine and set the bandwidth
7.4.3.1
Determining bandwidth
Too small/large a bandwidth
In order to set the correct value, the transformer's step voltage and nominal voltage must be known.
You have to set the bandwidth in such a way that the output voltage of the transformer (U
Act
) returns to within the specified tolerance bandwidth after the tap change. If too small a bandwidth is defined, the output voltage exceeds the bandwidth selected and the device immediately issues a tapchange command in the opposite direction. If a very large bandwidth is selected, this results in a major control deviation.

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

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 control 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.

Limit values
In the Limit values menu item, you can set all the parameters needed for limit value monitoring as relative or absolute values. You can set three limit values:
▪ Undervoltage U<
▪ Overvoltage U>
▪ Overcurrent I>
Limit value monitoring is used to reduce damage to the system periphery.
The following sections describe how you can set the parameters.
7.5.1
Setting undervoltage monitoring V<
You can use these parameters to set the limit values for an undervoltage.
Undervoltage monitoring prevents tap-change operations if there is a power cut.
Behavior
If the measured voltage U actual
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 [ ► 80]
has passed, the signaling relay activates. The Undervoltage U< message appears in the display. The message is reset as soon as the measured voltage U actual
again exceeds the limit value for undervoltage . If the measured voltage U actual

Compensation
You can use the "Compensation" function to compensate for the load-dependent 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
You can use R&X compensation and Z compensation at the same time. If you do not want to use one method, you have to set the associated parameters to 0.
If you are using the IEC 61850 control system protocol, you can only activate one of the two compensation methods at any one time. A control system command is available for this.
7.6.1
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 inductive voltage drop in V with reference to the secondary side of the voltage transformer. You also need to correctly set the transformer circuit used.

To keep the voltage constant for the consumer, you can use Z compensation to activate a current-dependent increase in voltage. Z compensation is not dependent on the phase angle φ and should only be used for small changes in phase angle.
You can also define a limit value to avoid excess voltage on the transformer.

Conditions for parallel operation
Compliance with the following general conditions is required for operating transformers in parallel:
▪ Identical rated voltages
▪ Transformer power ratio (< 3 : 1)
▪ Maximum deviation of short-circuit voltages (U
K nected in parallel < 10%
) for transformers con-
▪ Same number of switching groups
▪ The same current-transformer connection has to be used for all devices running in parallel
Parallel operation method
You can control up to 16 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. Parallel operation is activated using one of 2 status inputs or the control system.
The device supports parallel operation following the methods described below:
▪ Parallel operation following the "Circulating reactive current minimization" principle
▪ Parallel operation following the "Tap synchronization" (master/follower) principle
You must select the same parallel operation method (circulating reactive current minimization or tap synchronization) for all voltage regulators operating in parallel. Otherwise you cannot operate the devices in parallel.
The following sections describe how you can set the parameters. Ensure that you have set the following parameters when activating parallel operation:
▪ CAN bus address
7.9.1
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. If the value is set to 0 , then no communication takes place.

You must select the same parallel operation method for all voltage regulators operating in parallel.
The following sections describe how you can set the parameters for a parallel operation method.
297/07 EN Maschinenfabrik Reinhausen GmbH 2018
7 Operation
7.9.3.1
Setting circulating reactive current method
When the circulating reactive current parallel operation method is selected, 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 correction can be reduced or increased using the circulating reactive current sensitivity setting.
The circulating reactive current method is suited to transformers connected in parallel with a similar nominal output and short-circuit voltage U
K
and to vector groups with the same and different step voltages. This does not require any information about the tap position.
To set the circulating reactive current parallel operation method, proceed as follows:
1.
> Configuration > Parallel operation.
ð Parallel operation method
2.
Press or until circulating reactive current appears in the display.
3.
Press .
ð The parallel operation method is set.
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 optimum 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.
To set the circulating reactive current sensitivity, proceed as follows:

Setting circulating reactive current blocking
You can use this parameter to set the limit value for the maximum permissible circulating reactive current. If, during parallel operation, the circulating reactive current exceeds the set limit value, then the following event is activated:
▪ Parallel operation error
All devices operating in parallel are blocked. Depending on the set delay time for the parallel operation error message, the signaling relay Parallel operation error is activated.

7 Operation
7.9.3.2
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 voltage 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 received and their own position is exceeded, the followers switch to the tap position 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

The voltage regulator is designated as the master.
Follower The voltage regulator is designated as the follower.

Memory
With this you can undertake measured value memory settings. This configures the event memory and recorder function. The device has a memory capacity of 8 MB. The memory is split into 2 areas:
Average value memory
In the average value memory, all measured and calculated values are aver-
aged and saved using the average value intervals you set. You can set
[ ► 107] the average value intervals in stages between 1 and 40 seconds.
Event memory
Data is always saved to the event memory at the highest resolution without first being averaged. You can also determine how much memory space is to
be made available exclusively for the event memory [ ► 107].
Triggering event The data recorder can trigger an event depending on the undervoltage and/or overvoltage limit value that you can set. The data recorded here are stored in the measured value memory's event memory.
Chronological sequence To allow instances where values exceed or fall below the limit values to be better evaluated, the chronological sequence for the measured and calculated values also includes the last 10 seconds before values actually exceed or fall below the limit value. Each event is saved for a maximum of 5 minutes.
104 TAPCON® 250 297/07 EN Maschinenfabrik Reinhausen GmbH 2018
7 Operation
When an event is active, only the chronological sequence of the measured and calculated values is stored in the event memory.
As soon as there is no more free space in the event memory, the oldest values are overwritten by the new values measured. You can access information about the current event memory content via the Info menu.
Data recorder
The data-recorder module can be used to save the data listed below and display and evaluate it either on the display or using the TAPCON®-trol visualization software on a PC.
The following values are displayed:
▪ Measured values
– On-load tap-changer position
– Voltage
– Active current
– Reactive current
▪ Calculated values
– Active power
– Reactive power
– Apparent power
– Output factor
Calculation of the values stated depends on the measured values captured and the parameters set, for example:
▪ Current measuring circuit
▪ Primary current
▪ Voltage transformer data from primary and secondary sides
A correct calculation can only be undertaken if you have correctly entered the configuration data in full.
