While identifying the power substation as part of the system for a generation project or as a part of distribution grid, preliminary site selection is done by the utility based on the shortest length of the incoming (incomer) and outgoing …
capacitor''s output terminal. Thus, in the event that a set of fuses for a capacitor is open circuited, the stored energy will be shorted directly to ground, possibly destroying the copper contacts but assuring that the energy in the capacitors is depleted. Previous to any work on the modules, a soft dump-rod (Figure 10) is used.

3. Power capacitors and detuning reactors. The next step is to chose appropriate power capacitors. It means, that one needs to pay attention to its rated voltage and power. Since the capacitors will be working in series with reactors, what will cause the voltage at the capacitors'' terminals to rise.

General Design Rules 4 Reactors: Reactors are used in steps as detuned filters and are connected in series with capacitors. It must be designed to withstand fundamental and harmonic currents. Capacitors: Capacitors forms the core component in APFC equipment and plays a vital role in power factor correction.
Capacitors and Line Loss Reduction: By providing reactive power locally, capacitors reduce the need to transport reactive power over long distances in power lines, thus reducing line losses. This improves the efficiency of power transmission and distribution networks, as it decreases I²R losses (where I is current and R is resistance) in the ...
This filtering action is accomplished by the output capacitor, which offers little opposition to the high-frequency AC current. The unwanted output-ripple current passes through the output capacitor, and maintains the capacitor''s charge as the current passes to ground. Thus, the output capacitor also stabilizes the output voltage.

Modest surface mount capacitors can be quite small while the power supply filter capacitors commonly used in consumer electronics devices such as an audio amplifier can be considerably larger than a D cell battery. A sampling of capacitors is shown in Figure 8.2.4 . Figure 8.2.4 : A variety of capacitor styles and packages.
A capacitor bank is usually applied to an AC source of power. This helps to rectify or compensate for power factor lag or phase shift. These banks can also be connected to a DC power supply. This helps increase the comprehensive quantity of the power supply''s ripple current capacity or the stored energy.
