How does a capacitor affect line voltage?

A capacitor can increase the line voltage in an electrical system due to its ability to store and release energy. When connected to an AC circuit, the capacitor can counteract the effects of inductive loads, which tend to draw reactive power and can cause voltage drops. This reactive power compensation helps to improve the voltage profile of the system.

In particular, capacitors are used to correct power factor issues in electrical circuits, particularly those with inductive elements, such as motors and transformers. By supplying reactive power, capacitors help to maintain higher voltage levels, enabling more efficient operation of devices connected to the line. As the capacitor releases its stored energy, it effectively adds to the overall voltage, which can lead to an increase in line voltage under certain conditions.

Stabilizing voltage is another important function of capacitors, but the primary role regarding line voltage is their ability to counterbalance inductive effects and enhance overall voltage levels.
