1 Supply
1.1 Supply section
1.1.1 Number of supplies installed in parallel (1)
By default, Caneco BT proposes 1 supply; the user can configure up to 6 identical supplies in parallel. The
calculation in Caneco BT only takes into account the number of active supplies (max. and min.) when sizing the
installation, the difference between the number of supplies installed and the number of active supplies defines the
number of supplies available in the event of the loss of one of the active supplies. Caneco BT version 5.4 displays supply filenames in plain text (4)1.1.2 Max. number of supplies active simultaneously (2)
The Ik max values are calculated taking into account the max. number of active supplies in parallel.1.1.3 Min. number of supplies active simultaneously (3)
The Ik min values are calculated taking into account the min. number of active supplies in parallel.Displaying active supplies in CanecoBT v5.4
All the supplies installed will be displayed in the network single-line and board single-line diagrams
It is possible to display the (max. and min.) number of active supplies by configuring the supply label under the
4 2 1 3 Guide to new features in Caneco BT v5.4 © ALPI - 20126 Network section Reference Manual
The result of configuring the supply label makes it possible to view the min. and max. numbers of active supplies.
1.2 Network section
1.2.1 Harmonics
Selecting harmonic levels. This calculation is applicable for the standard.Harmonics level 15 %
15 % < Harmonics level 33 %
Harmonics level > 33 %
1.2.2 HV short-circuit power
Updated short-circuit power values are proposed by default in Caneco BT version 5.4Maximum power SkQ Max:
The default value of 433 MVA (the short-circuit power for the 20 kV grid) can be modified.Choose lower values in order to allow for e.g. high-impedance overhead LV lines. This parameter has only a small
effect on the Ik calculations.Minimum power SkQ Min:
Default value proposed: 125 MVA Enter a value different from the maximum value where your supply is a
transformer supplied at HV and if the HV supply is backed up by alternators. In this case, enter the short-circuit
power of these alternators.1.2.3 Additional factor
Enter the additional permitted current derating factor in accordance with external influences. This factor is not laid
down by standards, it is defined by the user.K loaded neut.:
Corresponds to the loaded neutral factor depending on the harmonic level. (applicable depending on the standard)

1.3.1 Miscellaneous
Spo: Cross-section of the P0 conductor connecting the HV/LV transformer to the MSB.Caneco BT 5.4 offers the possibility of calculating the Spo according to whether the core is Copper or Aluminium
Ra:Earth resistance value at the supply.
Ra is only displayed if the earthing system is TT.Contribution from motors:
The contribution from motors in the calculation of the Ik Max short-circuit currents is taken into account globally at
supply level.In Caneco BT this contribution is achieved in the form of a coefficient (1.00 = no motor contribution), it must be
defined by the designer (coefficient between 1 and 2) depending on the power of the motors in the installation.
1.3.2 Options for connection sizing
IB/In ratio:
Makes it possible to define the power actually provided by the supply (value expressed in % of the nominal power).
This item of information will make it possible to calculate the cross-section for the connection and the thermal trip
setting for the MSB. If unchecked, the overload criterion will not be checked If unchecked, the short-circuit criterion will not be checkedThese two options are useful in cases where the supply-MSB connection is imposed and does not have to be
verified by Caneco BT. Guide to new features in Caneco BT v5.4 © ALPI - 20128 Results Reference Manual
1.4 Results
1.4.1 SUPPLY IN
Rated current of the supply on load.
1.4.2 Ik3 Max
This is the max. symmetrical 3-phase short-circuit current, at the MSB, used for determining the breaking capacity
of the equipment and for calculating the thermal stresses for 3-phase circuits. This value is calculated according to the max. number of active short-circuit power.1.4.3 Ik2 Max
This is the max. symmetrical 2-phase short-circuit current, at the MSB, used for determining the breaking capacity
of the equipment and for calculating the thermal stresses for 2-phase circuits.1.4.4 Ik1 Max
This is the max. symmetrical single-phase short-circuit current, at the MSB, used for determining the breaking
capacity of the equipment and for calculating the thermal stresses for single-phase circuits. The Max values are calculated according to the max. number of active supplies in // -circuit power.1.4.5 IK2 Min
These are the min. 2-phase short-circuit currents (IK2: Ik phase-phase), at the MSB, when there is no neutral
present.1.4.6 IK1 Min
This is the min. single-phase short-circuit current (IK1: IK phase-neutral), at the MSB, if there is a neutral.
1.4.7 If
This is the fault short-circuit current (phasePE), at the MSB, used for checking the personnel protection condition
(indirect contact). The Min and If values are calculated according to the min. number of supplies in // -circuit power. ALPI - 2012 Guide to new features in Caneco BT v5.4 ©Reference Manual Results 9
2 Creating a new project from an existing project
This technique is a new feature in version 5.4, it makes it possible to handle a complex project (multiple supplies) in
the form of several .afr files.
