The program allows users to draw the single-line diagram of the system in the "Single-line" tab, located in the top left-hand corner of the main window.

In this diagram, the elements will have their electrical parameters and will be connected by means of conduits, where the type of cable with its characteristics and fittings will be defined.

This way, once the single-line diagram has been defined, the program will analyse the electrical parameters of each of the conduits and carry out the following checks based on the international IEC standard:

• Allowable current.
• Coordination amongst conductors and overload protection devices.
• Voltage drop.
