After the load flow calculation process, arrows are displayed in the single-line diagram, which display the direction of the current as well as its results.

CYPELEC Networks
The load flow calculation icon is substituted for a more representative icon, and includes quick access icon to its design options, amongst which is the possibility to define the global diversity factor.
Users can now define a global diversity factor for all the installation. The global diversity factor is applied to all buses and affects the calculation of the flow of loads of the installation.
The 2018.d version includes the option to define use factors for loads.
Use factors for loads are applied to each load independently and affect the calculation of the flow of the loads of the installation.
Loads can also be defined as a “spare load”, which are not considered in the calculation of the load flow.
The 2018.d version includes diversity factors in buses. This factor is applied to loads that are directly connected and affect the calculation of the flow of the loads of the installation.
From the first version of CYPELEC Networks, when a two winding transformer and a three winding transformer are edited, users can configure and the select the tap changer with the aim to regulate the voltage in the buses connected by the transformer.
After the analysis process, it may occur that the selection of the tap changer may cause the voltage of the controlled bus to lie outside the maximum values specified in the panel. As of the 2018.c version, when this case arises, the program can emit a warning to tell users to carry out a check. This warning is emitted if the new check “Voltage limits in the selection of the transformer tap changer” is activated, which is done in “General settings” > “Line checks”.
To manage the operation status of the installation elements, the 2018.c version includes the definition of the status loadcase. These loadcases define the status conditions of:
- Simple contacts and commutation contacts
- Fuses and switches
- Operation regimes in motors
- Operation regimes in generators
From the start, the circuit diagram is assigned to one loadcase (which can be unique) and is referenced on the left of the user interface.
Using the icon next to the reference of the visible loadcase, the loadcases can be generated in a panel created for this purpose and in which the status of all the previously mentioned elements are listed. Furthermore, the status can be changed directly in this panel.
The panel allows users to select the loadcase which is to be listed, as well as an option to only view the status differences of the elements of the selected loadcases.
CYPELEC Networks is now available to be downloaded at the BIMserver.center platform.
The following programs: CYPELEC Networks, CYPEFIRE Design, StruBIM Analysis, StruBIM Design, and StruBIM Foundations are available to be downloaded at the BIMserver.center platform.
CYPELEC Networks is a program for the analysis of power systems in electrical networks, created to assist project designers in the design and analysis of high/medium and low voltage installations.
It has a simple graphical interface that allows users to easily create and edit power diagrams and circuit diagrams. It incorporates a great variety of electrical equipment to create the diagrams such as, for example, power supplies, generators, transformers (two and three windings), low and medium voltage cables, high voltage transmission lines, capacitor banks, electrical loads and motors, etc... as well as protection and other electrical devices.
CYPELEC Networks analyses the flow of charges and calculates the voltages and phase difference in bars or buses, the currents in lines and branches, and the active and reactive power flows of the electrical system.
The design checks carried out in the program are based on the specifications of the NFPA 70 National Electrical Code (NEC).
CYPELEC Networks can be downloaded via the "BIMserver.center" platform. For its first version, it may be installed in Spanish or English. This tool is integrated in the Open BIM workflow using IFC standard exchange files.
More information on this new CYPE program can be found in CYPELEC Networks webpage.

CYPEURBAN and CYPELEC Networks (new programs with the 2018.a version) and StruBIM programs (from previous versions) are not installed with the complete CYPE program packet. These programs must be downloaded via the BIMserver.center web platform.
Furthermore, to be able to use either application, users must register in the BIMserver.center web platform. Once the program has been downloaded and installed, as well as the “BIMserver.center” synchroniser, new projects created by users should have an associated project lodged in the platform, hence allowing for the collaborative Open BIM workflow to take place.
