How Distribution Capacitor Banks Compensate for Inductive Loads
Capacitors are used in Electric Utility T & D Systems to "compensate" for the extra current load of inductive devices such as motors and transformers. On distribution feeders, the effects of that current are two-fold - causing greater line losses and greater voltage drop - both of which decrease the system''s overall efficiency.

Capacitors in Parallel. Figure 19.20(a) shows a parallel connection of three capacitors with a voltage applied.Here the total capacitance is easier to find than in the series case. To find the equivalent total capacitance C p C p, we first note that the voltage across each capacitor is V V, the same as that of the source, since they are connected directly to it through a conductor.

The red line corresponds to C 1, the green line corresponds to C 2, and the blue line corresponds to the effective combined C= ''C 1 in parallel with C 2 ''. We see that for the combined C, there is an impedance peak exceeding the Z T line at a frequency lying in between the two resonant frequencies F r-c1 and F r-c2 .
18.5 Capacitors and Dielectrics
The top capacitor has no dielectric between its plates. The bottom capacitor has a dielectric between its plates. Because some electric-field lines terminate and start on polarization charges in the dielectric, the electric field is less strong in the capacitor. Thus, for the same charge, a capacitor stores less energy when it contains a ...
