Here you have the option of calculating the reactive power, voltage, current and sin φ
of three-phase motors, for example.

Q=U x I x sin φ x √3
Blind Power: Q
Voltage: V
Current: I
sin φ
sin φ hast to be between -1 and 1 sein!
Please fill all mandatory inputs.

Here is an example:

A 400 V three-phase standard motor has a rated current of 34.516 amperes and a sin φ of 0.92.
What electrical binding power results from these specifications?

Q=U x I x sin φ x √3
Q=400 V x 34.516 A x 0.92 x √3
Q=22 kVAr

Units of measurement:

Reactive power Q=Kilovolt ampere reactive [KVAr]
Voltage U=Volt [V]
Current i=Ampere [A]
sin φ without
√3 or 1.73 without
