Capacitive loads and inductive loads, such as electric motors, can significantly affect the power factor. By introducing capacitors in the form of capacitor banks, power factor correction can be achieved, ultimately enhancing the overall efficiency of the electrical system.
Abstract: In large industry, power factor has become a majorissue in power system. Many industries have been using a capacitor bank for power factor improvement and reactive power compensation.
These capacitors have the unique characteristic of leading the voltage in AC circuits, meaning that the current waveform peaks before the voltage waveform. This phenomenon results in a leading power factor, which can influence the power factor of the entire electrical system.
The capacitor bank is used in industry for system stability, power factor improvement, and reactive power compensation. To reduce the switching transients of the capacitor bank, pre-insertion resistor technique is used. Most of the industrial loads are nonlinear in nature which aims at lagging power factor.
By influencing reactive power and power factor, capacitive loads can cause voltage fluctuations and instability if not properly managed. However, voltage regulation can be effectively maintained with the use of capacitor banks and power factor correction methods. Capacitive loads have both advantages and disadvantages in electrical systems.
With the use of capacitor bank, disturbance such as inrush current is increased in the system and can cause damage to the capacitor banks and other nearby equipment. This paper aims to study issues in terms of inrush current in the industry and its effect after switching the capacitor bank.
