elec calc™: High Voltage & Low Voltage (HV/LV) real-time calculations

elec calc ™ is design to manage installations with multiple voltage levels, both HV and LV in the same project, in alternating current for frequencies of 50 or 60 Hz.

Full calculation of the installation is carried out each time a change is made to the installation.

In addition to checking that the data entered is coherent, these real-time calculations include:

• Consumption calculation
• Power balance
• Verification of the cross-section area of the wiring systems
• Voltage drop calculation
• Short-circuit current calculation
• Verification of thermal and magnetic protections
• Verification of making and breaking capacities
• Verification of thermal stresses
• Touch voltage calculation

As this version of elec calc ™ does not manage the protection plan for the HV parts of the installation, it is not possible to check the thermal stresses. However, the software indicates the maximum withstand time of the cables according to the short-circuit currents. In addition, touch voltages are calculated and the software indicates the corresponding maximum tripping time.
