CAPACITOR BANK
Capacitor section ( rear internal view )
A capacitor bank is a group of capacitors connected together in a series or parallel configuration to provide reactive power compensation in electrical systems. Its primary function is to improve the power factor in electrical systems by supplying reactive power (also known as "volt-amps reactive" or VAR), which helps to balance the inductive loads (such as motors, transformers, etc.) in the system.
Types of Capacitor Banks:
Fixed Capacitor Banks: These are designed to provide a fixed amount of reactive power correction. They are simple in design and are commonly used in situations where the load is relatively constant.
Automatic Capacitor Banks: These systems automatically adjust the number of capacitors connected to the circuit based on the changing load, providing dynamic power factor correction.
Detuned Capacitor Banks: These are specifically designed to avoid resonating with the system’s inductive components at certain frequencies, which can cause harmful effects like harmonics.

Power Factor Correction
A low power factor indicates that the system is inefficient because more power is needed to perform the same work. By adding a capacitor bank, the reactive power demand from the utility grid is reduced, improving efficiency.
Voltage Stabilization
Maintain stable voltage levels in the system, especially in places where voltage fluctuation occurs due to reactive power demands.
Reduced Electricity Costs
Many utility companies charge additional fees if a customer’s power factor is low. By using capacitor banks to improve the power factor, companies can avoid these extra charges.
