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 …

REACTIVE POWER – Applied Industrial Electricity
As with the simple inductor circuit, the 90-degree phase shift between voltage and current results in a power wave that alternates equally between positive and negative. This means that a capacitor does not dissipate power as it reacts against changes in voltage; it merely absorbs and releases power, alternately. A Capacitor''s Reactance
