Shunt capacitors are passive electrical components that are connected in parallel (or "shunt") with load circuits. Their primary function is to improve the quality of the power supply by enhancing the power factor of electrical systems. By doing so, they reduce losses in the supply chain and allow for more efficient energy distribution.

Shunt capacitor banks are used to improve the quality of the electrical supply and the efficient operation of the power systems. They are inexpensive solutions and can be easily and quickly installed anywhere on the network.
While both shunt and series capacitors are crucial in power systems, they serve different functions and are applied in distinct configurations. Here’s a comparison of their characteristics: Shunt Capacitors: Connected in parallel with the load. They provide reactive power to the system and improve the overall power factor.
The primary weakness of the shunt capacitor units is that their reactive power generation is relative to the square of the voltage, and accordingly when the voltage is low and the electrical system needs them most, they are delivering the least amount of the reactive power. The capacitor unit is the essential element of a shunt capacitor bank.
The working principle of shunt capacitors in power systems can be explained through a combination of reactive power management and energy storage. Here are the key aspects: Capacitors are connected in parallel with the load in the electrical circuit.
