Here you have the possibility to calculate the reactive power, the voltage, the current, and the sin φ
of e.g., single-phase motors.

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

For Example:

A 230 volt single-phase AC motor has a rated current of 8.56 amps and a sin φ of 0.9.
What electrical binding power results from these specifications? 

Q = V x I x sin φ
Q = 230 V x 8.56 A x 0.92
Q = 1.772 kVAr


Measuring Units:

Reactive power  Q = Kilovolt ampere reactive [KVAr]
Voltage                V = Volt [V]
Current                I = Ampere [A]
sin phi                       no measuring unit
