Enter the power in kilowatts (kW), the voltage in volts (V), and the power factor into the calculator to determine the amps per phase. This calculator helps in analyzing the electrical load in a three-phase power system.
Amps Per Phase Formula
The following formula is used to calculate the amps per phase.
APP = {P * 1000}/{sqrt{3} * V * PF}Variables:
- APP is the amps per phase (A)
- P is the power (kW)
- V is the voltage (V)
- PF is the power factor (unitless)
To calculate the amps per phase, multiply the power by 1000 to convert it to watts, then divide by the product of the square root of 3, the voltage, and the power factor.
What is Amps Per Phase?
Amps per phase is a measure of the current flowing through one phase of a three-phase electrical system. It is a crucial parameter for designing and operating electrical systems, ensuring that the current is within the safe operating limits of the electrical components and conductors. The power factor, which represents the phase difference between voltage and current, is also taken into account when calculating the amps per phase.
How to Calculate Amps Per Phase?
The following steps outline how to calculate the Amps Per Phase.
- First, determine the power (P) in kilowatts (kW).
- Next, determine the voltage (V) in volts.
- Next, determine the power factor (PF), which is a unitless number typically ranging from 0 to 1.
- Next, gather the formula from above = APP = (P * 1000) / (√3 * V * PF).
- Finally, calculate the Amps Per Phase (APP) in amperes (A).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Power (P) = 50 kW
Voltage (V) = 400 V
Power Factor (PF) = 0.8
