Here you have the possibility to calculate the active power, the voltage, the current, and the cos φ
of e.g., three-phase motors.
P = U x I x cos φ x √3
For Example:
A 400 volt three-phase standard motor has a rated current of 25.18 amps and a cos φ of 0.86.
What is the electrical power resulting from these specifications?
P = V x I x cos φ x √3
P = 400 V x 25.18 A x 0.86 x √3
P = 15.003 kW or 15 kW
Measuring Units:
Active power P = Kilowatt [kW]
Voltage V = Volt [V]
Current I = Ampere [A]
cos φ no measuring unit
√3 or 1.73 no measuring unit
