Here you have the possibility to calculate the reactive power, the voltage, the current, and the sin φ
of e.g., three-phase motors.
Q = U x I x sin φ x √3
For Example:
A 400 volt three-phase standard motor has a rated current of 34.516 amperes and a sin φ of 0.92.
What is the electrical binding power resulting from these specifications?
Q = V x I x sin φ x √3
Q = 400 V x 34.516 A x 0.92 x √3
Q = 22 kVAr
Measuring Units:
Reactive power Q = Kilovolt ampere reactive [KVAr]
Voltage V = Volt [V]
Current I = Ampere [A]
sin φ no measuring unit
√3 or 1.73 no measuring unit
