1. Apparent power of inductive load S × power factor of load COSφ = reactive power Q to be compensated:

S × COSφ = Q

2. Phaseless power Q' =? Compensated three-phase reactive power Q/3

3, because: Q = 2Ï€fCU^2,

and so:

When the 1μF capacitor and rated voltage are 380v, the reactive capacity is Q=0.045Kvar

When the 100μF capacitor and rated voltage are 380v, the reactive capacity is Q=4.5Kvar?

When the 1000μF capacitor and rated voltage are 380v, the reactive capacity is Q=45Kvar.

4. “How much capacity does a large load need?”:

1) You can first calculate the reactive power Q of the three phases;

2) Calculate the reactive power Q/3 of 1 phase;

3) Calculate the capacitance C of the 1-phase;

4) Then connect the triangles!

5, because: Q = 2Ï€fCU^2,

and so:

When the 1μF capacitor and rated voltage are 10Kv, the reactive capacity is Q=31.4Kvar

When the 100μF capacitor and rated voltage are 10Kv, the reactive capacity is Q=3140Kvar

6, because: Q = 2Ï€fCU^2, so:

When the 1μF capacitor and rated voltage are 220v, the reactive capacity is Q=0.015Kvar

When the 100μF capacitor and the rated voltage are 220v, the reactive capacity is Q=1.520Kvar?

When the capacitor is 1000μF and the rated voltage is 220v, the reactive capacity is Q=15.198Kvar.
