What Does a Capacitor Bank Do. A capacitor bank is used to store electrical energy and improve the performance of electrical systems by providing reactive power support. Its main functions are: Power Factor Correction: In power systems, electrical loads often consume both real power (used to do work) and reactive power (needed to maintain voltage levels).

Electrical Substation Components. The substation components, like isolators, bus bars, power transformers, etc., are interconnected. These components are crucial for the installation of the substation. Electrical substation designing is a highly complex process that requires careful planning and engineering expertise.

The advantages of this arrangement are low maintenance, low initial cost and simple operation. The drawback of this arrangement is if any repair work is to be done on bus-bar, complete system get interrupted.

As we know it is impractical to connect multiple conductors at one point. Hence we use bus bars, where these connections can be done spaciously and conveniently. So let's start with different bus-bar schemes or systems in an electrical substation.
The indoor 11kV sub-stations often use single Busbar Arrangements in Substations. Fig. 25.5 shows single Busbar Arrangements in Substations. There are two 11 kV incoming lines connected to the bus-bar through circuit breakers and isolators.
Each bus-bar has the capacity to take up the entire sub-station load. The incoming and outgoing lines can be connected to either bus-bar with the help of a bus-bar coupler which consists of a circuit breaker and isolators. Ordinarily, the incoming and outgoing lines remain connected to the main bus-bar.
(iii) Duplicate bus-bar system: This system consists of two bus-bars, a “main” bus-bar and a “spare” bus-bar. Each bus-bar has the capacity to take up the entire sub-station load. The incoming and outgoing lines can be connected to either bus-bar with the help of a bus-bar coupler which consists of a circuit breaker and isolators.
