II. Overview of Capacitor Banks
A. Function and Purpose of Capacitor Banks
Capacitor banks serve several vital functions in electrical systems:
1. **Power Factor Correction**: One of the primary roles of capacitor banks is to improve the power factor of electrical systems. A poor power factor can lead to increased energy costs and reduced system efficiency. By supplying reactive power, capacitor banks help to offset inductive loads, thus improving the overall power factor.
2. **Voltage Stabilization**: Capacitor banks help maintain voltage levels within acceptable limits, especially during peak demand periods. By providing reactive power support, they stabilize voltage fluctuations, ensuring a consistent supply of electricity.
3. **Harmonic Filtering**: Capacitor banks can also mitigate harmonic distortion in electrical systems. Harmonics can cause overheating, equipment failure, and reduced efficiency. By filtering out these unwanted frequencies, capacitor banks enhance the quality of the power supply.
B. Types of Capacitor Banks
There are three main types of capacitor banks:
1. **Fixed Capacitor Banks**: These are designed to provide a constant amount of reactive power. They are typically used in applications where the load is stable and predictable.
2. **Automatic Capacitor Banks**: These systems adjust the amount of reactive power supplied based on real-time load conditions. They are ideal for applications with variable loads, as they can optimize power factor correction dynamically.
3. **Switched Capacitor Banks**: These banks consist of multiple capacitor units that can be switched on or off as needed. This flexibility allows for precise control over reactive power compensation.
III. Key Specifications and Features
