Cable sizing calculations for phase, neutral and earthing conductors are based on the following criteria:
During the electrical design ElectricalOM acts interactively and indicates to the user useful information and calculations. Instead of having a centralised calculation button the software intelligently re-calculates the circuits with any change and produces quick and useful indications so the user understand what's being affected during the change
Correction factors affect the cable size selection. ElectricalOM considers the following correction factors during the cable sizing calculations:
In ElectricalOM the loads are automatically summed for each phase. The user can easily review the connected, diversified loads including any spare percentage of the selected distribution circuit
Calculations and checks based on Manufactures specific data for busbar thermal limit and peak short circuit withstand values
ElectricalOM checks all the protective devices in the electrical installation and warns the engineer about any discrimination problems discovered
An intuitive and user-friendly reporting environment allows the user to choose the reports to print and including with the cover and contend pages. Reports can be directly printed or exported to pdf, document or excel formats. Various calculation reports are available:
