Electrical Energy Calculator
This calculator computes the electrical energy consumption of a system given the voltage, current, resistance, and time. Provide exactly 2 of the 3 electrical parameters (V, I, R).
Input Parameters
- Power: Total power (kW, hp, VA, kVA, MVA)
- Power Option: Unit of measurement selection
- Voltage: System operating voltage
- Phase: Single-phase, three-phase, or DC
- Power Factor: For AC systems (if applicable)
Three-Phase AC Supply
Full load current calculations for three-phase AC systems:
Power in Kilowatts (kW)
\[I = \frac{1000 \cdot P}{\sqrt{3} \cdot V \cdot pf}\]Power in Kilovolt-Amperes (kVA)
\[I = \frac{1000 \cdot S}{\sqrt{3} \cdot V}\]Power in Horsepower (hp)
\[I = \frac{745.7 \cdot P}{\sqrt{3} \cdot V \cdot pf}\]Single-Phase AC Supply
Full load current calculations for single-phase AC systems:
Power in Kilowatts (kW)
\[I = \frac{1000 \cdot P}{V \cdot pf}\]Power in Kilovolt-Amperes (kVA)
\[I = \frac{1000 \cdot S}{V}\]Power in Horsepower (hp)
\[I = \frac{745.7 \cdot P}{V \cdot pf}\]DC Supply
