Applications of Series Compensation. Series capacitors are used in transmission systems to modify the load division between parallel lines. If a new transmission line with large power transfer capacity is to be connected in parallel with an already existing line, it may be difficult to load the new line without overloading the old line.

Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series. In contrast, when capacitors are placed in series, it is as if the plate distance has increased, thus decreasing capacitance.

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
If we use two capacitors, we can power the lamp for longer. Let''s say capacitor one is ten microfarads and capacitor two is 220 microfarads. How do we calculate the total capacitance? Well, that''s very simple. The answer is 230 microfarads. The capacitors combine in parallel, so 10 + 220 equals 230 microfarads.

To cancel the leakage inductance, compensating capacitors are attached in parallel or series to reduce the circulation of high reactive current (Barman et al., 2015; Houran et al., 2018). As a result, for the primary (Tx) coil of the WPT system, the main role of compensation capacitor is to reduce the VA rating of the input source.
