Software for Electrical Design | Cable Sizing Calculations
ElectricalOM is the ideal cable sizing software
Cable sizing calculations for phase, neutral and earthing conductors are based on the following criteria:
- Source characteristics (earthing system, fault levels etc)
- Load current
- Voltage drop
- Short circuit and Earth fault currents
- Protective devices disconnection time
- Cable energy withstand based on the Protective devices let-through energy
- Earth fault loop impedance checks
- Use of earth fault protection/RCD devices
- Touch voltage limit
- Unbalanced load
- Power factor
- Harmonics
- Motor starter type (direct on-line, star-delta, soft-start etc.)
- Motor starting current
- Motor minimum starting voltage
- Motor contribution to short circuit
- Integrated AC & DC Systems
- DC Battery Characteristics
