Although designs and layouts vary, all capacitor banks are composed of a ''bank'' of several capacitors connected together in series or in parallel. Capacitor banks can be used for voltage regulation, harmonic filtering, and surge suppression – let''s take a closer look at these critical devices and how they are used in industry.
Capacitor banks are composed of many individual capacitor units electrically connected to function as a complete system. Units are connected in series to meet required operating voltage, and in parallel to achieve the required kvar (graphically represented in Figure 7). Capacitor banks require a means of unbalance protection to avoid overvoltage conditions, which would lead to
This reactive power is provided by the capacitor bank installed parallel to the load. Capacitor banks act as a source of local reactive power and thus less reactive power flow through the line. By using a capacitor bank, the power factor can be maintained near to unity.
