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.

5.6 Electric Field Lines
As a result, if the field lines are close together (that is, the field line density is greater), this indicates that the magnitude of the field is large at that point. If the field lines are far apart at the cross-section, this indicates the magnitude of the field is small. Figure 5.30 shows the idea.
