Boost capacitors increase the voltage indefinitely. False. Boost capacitors, also known as energy storage capacitors, can significantly increase voltage for short durations. However, they cannot increase voltage indefinitely. The amount of energy stored in a capacitor is limited, and the voltage boost is temporary.
The location of low-voltage capacitors in an installation can either be central (one location for the entire installation), by sector (section-by-section), at load level, or a combination of the latter two.

As power distribution system load grows, the system power factor usually declines. Load growth and a decrease in power factor leads to Reduced system capacity. Capacitors offer a means of improving system power factor and helping to correct the above conditions by reducing the reactive kilovar load carried by the utility system.
In addition, proper switching prevents overvoltage, undesirable voltage flicker and helps the capacitors perform the task they were installed to do. Voltage spikes or surges occur when switching capacitors because the switch usually closes when the system voltage is not at a zero voltage crossing point.
In the electric utility industry, capacitors are used in electrical circuits to reduce the reactive demand on the circuit. Reducing the reactive demand on the circuit will release system capacity for other purposes, improve the voltage profile of the circuit, reduce I2R losses in the circuit, and improve the power factor of the circuit.
Capacitors offer a means of improving system power factor and helping to correct the above conditions by reducing the reactive kilovar load carried by the utility system. For optimum performance and avoidance of these undesirable conditions, prudent utility planners attempt to maintain as high a power factor as economically practical.
Distribution capacitors can reduce system line losses, as long as the system power factor is not forced into a leading mode. Line losses at 80 percent leading power factor are just as detrimental as line losses at 80 percent lagging power factor.
This type of operation provides better utilization of existing investment in equipment and may make possible the deferral of costly system improvements. To see how a capacitor affects a power system, look first at the sine-wave-shaped instantaneous voltage wave generated by a rotating generator.
