Three phase electrical systems
This calculator lets you quickly and accurately calculate the current in a three-phase system based on the power and voltage values.
Formula for calculating the current in a three-phase system
Certainly! The formula for calculating the current in a three-phase system is as follows:
Current (I) = Power (P) / (√3 * Voltage (V) * Power Factor (PF))
Where:
- Current (I) is the current flowing through each phase in amperes (A).
- Power (P) is the total power consumed by the three-phase system in kilowatts (kW).
- Voltage (V) is the line-to-line voltage of the three-phase system in volts (V).
- Power Factor (PF) is the power factor of the three-phase system, which represents the ratio of real power (kW) to apparent power (kVA) and is dimensionless.
To calculate the current, divide the power by the product of the square root of 3, the voltage, and the power factor. This formula assumes a balanced three-phase system. In an unbalanced system, the currents in each phase may differ.
Using this formula in our Three Phase Current Calculator will enable you to obtain accurate, current values based on the power and voltage inputs.
To use our 3 Phase Current Calculator
To use our Three Phase Current Calculator, follow these simple steps:
Enter the line-to-line voltage (V):
Start by inputting the line-to-line voltage of the three-phase system in volts (V). This value represents the voltage between any two phases and is typically labeled as “V” in electrical diagrams.
Enter the power factor (PF):
Next, provide the three-phase system’s power factor (PF). The power factor is a dimensionless value between 0 and 1, representing the system’s ratio of real power (kW) to apparent power (kVA). It indicates the system’s efficiency and is often provided in electrical specifications or can be calculated using power measurements.
Enter the total power (P):
Now, input the total power (P) consumed by the three-phase system in kilowatts (kW). This value can be obtained from the system specifications or by measuring the power using appropriate instruments.
Calculate the current:
Once you have entered the necessary values, click on the “Calculate” button, and our Three Phase Current Calculator will provide you with the current (I) flowing through each phase in amperes (A). The result will be displayed for each phase, as well as the total current.
Balanced three-phase system
Remember, the current will be the same in a balanced three-phase system in each phase. However, in an unbalanced system, the currents may differ. Our calculator accounts for both scenarios, providing accurate, current values for each phase.
