Power factor is an important parameter in an electrical system that measures how efficiently electrical power is being used. A low power factor can cause several problems, such as increased energy consumption, higher electricity bills, and reduced efficiency of electrical equipment. A capacitor bank can be used to improve and correct the power factor by compensating for the reactive power in the system, thus reducing the amount of reactive power required from the electrical grid.
Capacitor banks can be used to control the level of supply voltage in the substation. Voltage fluctuations can cause equipment damage and affect the efficiency of electrical equipment. Capacitor banks can help stabilize the voltage level by providing reactive power to the system, which helps to maintain a stable voltage level.
Capacitor banks can improve the power handling capacity of the substation by reducing the amount of reactive power required from the electrical grid. When the power factor is improved, the substation can handle more active power, which can increase the capacity of the electrical system. This can be particularly useful during periods of high demand, where the substation may need to handle more power than usual.
Capacitor banks help in reducing the phase difference between the voltage and current in the electrical system. When an electrical load is inductive, such as a motor or a transformer, it draws reactive power from the electrical system. Reactive power is necessary for creating and sustaining magnetic fields, but it does not contribute to doing useful work. This can result in an inefficient power system with a low power factor.
Capacitor banks compensate for the reactive power in the system by providing reactive power to the load. This helps to reduce the amount of reactive power required from the electrical grid, which in turn reduces energy consumption, improves the efficiency of electrical equipment, and increases the capacity of the electrical system.
Moreover, capacitor banks are used for power factor correction. Power factor correction involves bringing the power factor closer to unity, which is a measure of the system's efficiency. A low power factor can lead to energy wastage, higher energy bills, and reduced efficiency of electrical equipment. Capacitor banks improve the power factor of the electrical system by reducing the reactive power component and increasing the real power component of the electrical load.
