This tool helps you accurately estimate electrical project costs by inputting various detailed factors.
How to Use the Electrical Estimator Calculator
This calculator helps you estimate various important parameters for electrical circuits. Fill in the following fields with accurate values for the most precise calculation:
- Voltage (V): The voltage of the electrical circuit.
- Amperage (A): The current running through the circuit.
- Phases: Choose between single-phase and three-phase systems.
- Efficiency (%): The efficiency of the electrical components involved.
- Power Factor: The power factor should be a value between 0 and 1.
- Conductor Length (m): The length of the conductor in meters.
- Conductor Resistance (Ohm/km): The resistance of the conductor per kilometer.
Click on the “Calculate” button to get the results. The results will display the Total Power, Line Loss, and Voltage Drop.
How it Calculates the Results
The Total Power is calculated using the formula:
- For Single-phase: ( text{Total Power} = text{Voltage} times text{Amperage} times text{Power Factor} times text{Efficiency} )
- For Three-phase: ( text{Total Power} = text{Voltage} times text{Amperage} times sqrt{3} times text{Power Factor} times text{Efficiency} )
Line Loss is calculated as:
- For Single-phase: ( 2 times text{Length} times text{Resistance} times left( text{Amperage}^2 right) / 1000 )
- For Three-phase: ( 3 times text{Length} times text{Resistance} times left( text{Amperage}^2 right) / 1000 )
The Voltage Drop is calculated as:
( text{Total Resistance} times text{Amperage} )
Where Total Resistance is:
- For Single-phase: ( 2 times text{Resistance} )
- For Three-phase: ( 3 times text{Resistance} )
Limitations
This calculator assumes ideal conditions and does not take into account various factors that might affect real-world applications such as ambient temperature, conductor material, and installation conditions. Always consult with a professional for precise electrical estimations and designs.
