Software for electrical and photovoltaic engineering

New features 2020 Series - Electrical grid calculation

Electro Graphics releases the latest 2020 Series of electrical and photovoltaic design software. Here are the most important features and enhancements introduced about Electrical grid calculation in the  software Ampère line and EGlink.

Starting asynchronous motors in direct, star / delta and soft starter mode

Ampère 2020 manages four different types of engine starting defined as:

  • Direct starter;
  • Star / delta starter;
  • In line soft starter;
  • Soft starter delta.

Ampère 2020 allows the dimensioning and selection of all the elements of the starting system, with the analysis of currents and voltage drops, as well as failure analysis. In particular, the initial peak current has been added, calculated according to the IEC 60947-4-1 standard.

Soft starter electrical characteristics

Soft starter start-up can be done online or in delta, or how to start directly or how to start star-triangle.

Auxiliary elements for control and protection devices on functional diagrams

The automatic drawing of the single-line diagram can now include the auxiliary circuits that implement the command and control functions connected to the power devices of the electrical panel.

These circuits, defined as "auxiliary functional diagrams", can be assigned to the protection devices in the Ampère electric grid’s units; The circuits can be selected from a library that can be completely customized in CADelet, iDEA, Eplus.

For the more complex cases, the auxiliary functional diagrams can be composed of several elements also referring to several users.

Calculation and verification of bars inside panel according to CEI UNEL 01433-72

Ampère 2020 now manages calculation and verification of bars inside the panel according to the CEI UNEL 01433-72 standard

In detail, Ampère 2020 manages the current flow rates for flat glossy bars of electrolytic copper with sharp edges on air, with natural ventilation.

This is the sizing of copper bars most used inside the panels, and not only.

The Ampère sizing considers all the characteristics of the bars specified by the standard, including current (DC or AC), number of bars in parallel, derating coefficients for vertical or horizontal arrangement. The designer can choose the installation, and Ampère automatically calculate the section of the bar, also considering the derating coefficients. On mesh, the units with bars are represented with a special graphic, similar to the ducts in the bar, but similar in color to copper.

MV measurement and protection transformers (CT, VT and HT)

For medium voltage units it is now possible to insert the protection measure transformers CT, VT and HT.

For each device it is possible to set up to 5 different types of protection / measurement transformers, useful for translating the input (voltage or current) into an adequate signal for general protection.

For each CT / VT protection / measurement transformer it is possible to edit the transducer parameters or select it from the archive.

Transformer saturation CT VT HT

Dynamic analysis on all types of fault current (Ik, Ik ’, ik’ ’and Io) and verification of saturation of the CT / HT

Ampère executes a dynamic analysis on all types of fault current (Ik, Ik ’, ik’ and Io) and verifies the saturation of the CT / HT.

A chart represents the results of the individual saturation verify distinguishing linear CTs from non-linear CTs: positive results, errors and warnings are reported.

Extension and updating of the device databse

New series for all types of devices have been added to the Ampère database.


EGlink: BIM integration between Revit© MEP and Ampère Professional

EGlink is an interchange plug-in between Autodesk Revit and Ampére Professional and represents the Electro Graphics's response to BIM (Building Information Modeling) process mode.  Here are the most important features and enhancements introduced in EGlink 2020.

Compatibility with Revit 2020

EGlink is now compatible with Revit 2020 also.

Recognizing cable routes in Revit and cable routing

The new EGlink routing function recognizes the path of the cables among the electrical elements of a project.

EGlink scans the cable tray and ducts designed in Revit and connected to electrical equipments and allows to evaluate the routing of electrical circuits.

EGlink rebuilds the electrical grid and identifies the shortest path of each circuit in order to join the electrical panels and devices that this circuit connects.

EGlink calculates the optimal cable routing, the real length and the proximity.

Calculation of the optimal route for cables, real length and proximity

The routing of electrical circuits, an operation automatically performed by the EGlink software, allows you to have the following advantages.

  • Actual estimate of the length of the connection cables.
  • Exact value of the number of proximity circuits, that is of the cables that share the same cable duct, for a correct calculation of the capacities.
  • Assignment of the laying type to the unit depending on whether the cable passes through cableway or pipes.
  • Check of the cramming, also with graphic display, to identify the elements that do not guarantee the removal of the cables according to the standards.
  • Use of customized labels showing the data of the cramming and the list of circuits that transit on certain sections of cable trays.

Appropriate specific functions allow to modify the shorter routing calculated by the software if it does not represent the designer's needs.

It is possible to exclude specific sections of conduit and set routing rules based on the exclusions made: EGlink highlights alternative routes for a quick evaluation by the designer.

Calculation of overall dimensions of cables and cable duct filling

The new function calculates the overall dimensions of the cables and allows you to preview of the filling of the cables inside cable tray and ducts drawn in the Revit model. The pipelines are highlighted with different colors based on the filling state.
