Arc line loss represents the energy dissipated as heat when an electrical arc occurs in a system. Understanding this loss is essential for designing efficient electrical systems and preventing equipment damage.
Formula
Arc line loss is calculated using the power formula:
[\text{Arc Line Loss} = \text{Arc Current} \times \text{Arc Voltage}]
Where:
- Arc Line Loss (ALL) is the energy dissipated as heat (in watts)
- Arc Current (AC) is the current flowing through the arc (in amps)
- Arc Voltage (AV) is the voltage across the arc (in volts)
Calculation Example
For an electrical arc with:
- Arc Current: 7 amps
- Arc Voltage: 8 volts
[\text{Arc Line Loss} = 7 \times 8 = 56 \text{ watts}]
This means 56 watts of power is being dissipated as heat in the arc.
Why Arc Line Loss Matters
| Impact | Description |
