App required for installers, designers and electricians, who wish to have at hand all the tools necessary for a correct dimensioning and verification of the electrical plant. Now you have all the design data available in the places where you need an immediate evaluation and control. There are two tools: 1) Project calculation Allows a fast calculation of the current absorbed by a load in low and medium voltage, the dimensioning of the electric cable, the verification of the voltage drop and of the working temperature of the cable. The App provides the freedom to set any voltage and frequency (50-60 Hz, DC) power supply, the load type (three-phase, single phase), the power factor and the ambient temperature. There are multiple International low voltage installation tables (CEI 64-8, IEC 60364, NF C 15-100, BS 7671, UNE 20460, NBR 5410) and as many for medium voltage. 2) Projects The design file of an electrical plant created by the program Ampere of Electro Graphics can be sent directly to your mobile device via email attachment or by copying the files on the device. Projects can be opened, viewed and edited on the device and then transferred to the computer with the same tools, and then proceed to upgrade the project using the "Update from Ampere Mobile". You can then work directly on the 'field' with your project Ampere, run verifications on sight, shooting and storing pictures for each unit, edit useful comments to be reviewed calmly in the office or to send to your colleagues in real time. The installer can use the app to share with you the project itself, promptly reporting any problems that may arise during the implementation phase of the electrical plant, and thus receive immediately any reviews. The application does not need internet connection.
