In this section, we delve into a practical case study involving the selection and calculation of a capacitor bank situated within a 132 by 11 KV substation. The primary objective of this capacitor bank is to enhance the power factor of a factory.
Each phase consists of 12 units or 36 units for a three-phase bank. Each unit should be rated 9.96 kV and 667 kvar. For a fuseless bank, capacitor units are only connected in series (illustrated in Figure 10); they are never placed in parallel like an externally or internally fused capacitor bank.
Capacitor Bank Calculation Formula: The most basic formula for sizing a capacitor bank is based on the power factor correction needed and the total reactive power load. Regular capacitor bank maintenance is essential for ensuring that the system operates smoothly and prevents failures.
IEEE 18 specifies certain physical dimensions for capacitor units, such as spacing between bushings and the mounting hole spacing. The spacing between bushings determines the maximum unit voltage rating, which is typically 20kV for two bushing units and 25kV for single bushing units.
Common ratings include: 100 kvar capacitor bank for medium-sized applications. 250 kvar capacitor bank for large systems. 500 kvar capacitor bank for industrial power systems. When purchasing a capacitor bank, it's important to consider both the capacitance rating and the capacitor bank price.
