Connection:
Enter the type of connection to be used in the calculation
- Three Phase
- Single Phase
- Two Phase + N
- Single Phase Center Tapped
- Direct Current (DC Calculations)
Line Voltage:
Line voltage is the voltage between phases in a multi-phase system. or phase to neutral voltage in a single phase system.
Phase Voltage:
Phase Voltage is phase to earth voltage (Incoming Phase-Earth Voltage)
Fault Limiting Device:
Having the Fault Limiter box ticked, enables the Maximum Fault Limit (kA) field below it.
Maximum Fault Limit (kA):
The maximum fault current of the fault limiting device in kA
Enabled by the Fault Limiting Device Checkbox
Inverter Settings.
Use the inverter button to enter details to simulate incoming supply from an Inverter. This will be used for calculating Voltage Rise and required Cable Capacity.
Rating:
Rating of the current supply in kVA
Current:
Resulting current from the inverter in amps (A)
Power Factor:
The power factor of the supply, entering a power factor of 1 is a unity supply
Allowed Growth Factor (%):
Percentage of the current supply to allow for future growth or expansion on this cable run. Entering 0 will calculate only the existing supply
Single Phase Inverter:
If checked, indicates this is a single phase inverter, even if the cable supply is 3 phase
