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.
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 capacitive reactance (X_c) of a capacitor is defined as: Xc=12πfC Xc =2 πfC 1 Where: As the frequency of the alternating current (AC) increases, the capacitive reactance decreases. This relationship allows shunt capacitors to effectively counteract the inductive reactance generated by loads such as motors and transformers.
Power Factor Correction: Many industrial loads operate with inductive characteristics, which results in a lower power factor. Shunt capacitors help improve the power factor by providing leading reactive power, thus reducing the demand for reactive power from the grid.
