Reactive Power Compensation of Reactive Components
In a DC circuit, the product of "volts x amps" gives the power consumed in watts by the circuit. However, while this formula is also true for purely resistive AC circuits, the situation is slightly more complex in an AC circuits containing reactive components as this volt-amp product can change with frequency affecting the circuits reactive power.
What is Reactive Power Compensation? – Capacitor Connect
There is voltage drop across the line from point A to point B, equal to. V = V 1 – V 2 = i (R + jX). Or V 1 – V 2 ≈ i (jX) if R << X.. Z is the net impedance between points A and B from all sources (line self- and mutual inductances, capacitance to ground etc.). The drop V can be significant, and efforts are made to reduce this drop, or reduce the effect of reactance X …
