Electrical Load Calculator – Accurate Home Load Estimation

This electrical load calculator will help you determine the total power consumption of your electrical devices.

Electrical Load Calculator

This electrical load calculator helps you determine the power consumption (in watts) of an electrical device or system based on the given input values. Simply enter the voltage (in volts), current (in amperes), power factor (0-1), and phase (1 for single-phase, 3 for three-phase) to calculate the power in watts.

How to Use:

  1. Enter the Voltage (V) in the provided input box.
  2. Enter the Current (A) in the provided input box.
  3. Enter the Power Factor (0-1). This value represents the efficiency of the electrical system.
  4. Enter the Phase (1 or 3). Input 1 for single-phase systems and 3 for three-phase systems.
  5. Click the “Calculate” button to compute the power in watts.
  6. The result will be displayed in the “Result” field.

How It Calculates:

The electrical load calculator determines the power (in watts) using the following formulas:

  • For single-phase systems (Phase = 1):
    Power (W) = Voltage (V) * Current (A) * Power Factor
  • For three-phase systems (Phase = 3):
    Power (W) = Voltage (V) * Current (A) * Power Factor * √3

Limitations:

This calculator assumes purely resistive loads and does not account for any harmonics or other non-linear characteristics that might be present in more complex systems. The accuracy depends on the precision of the input values.
