Using capacitors to supply reactive power reduces the amount of current in the line. Since line losses are a function of the current squared,I2R, reducing reactive power flow on lines significantly reduces losses. Engineers widely use the “2/3 rule” for sizing and placing capacitors to optimally reduce losses.
Research results The placement of capacitors resulted in improved voltage levels across the distribution network. Voltage deviations from the nominal value were significantly reduced. There was a notable reduction in active power losses (I2R losses) throughout the distribution lines.
Also the Capacitors reduce the current flowing through the distribution lines, which directly decreases I2R losses (active power losses). This leads to more efficient energy distribution, and Reducing Active Power Losses. The Capacitors provide reactive power locally, which improves the power factor of the system.
Conclusion Capacitor banks are a common solution for reducing power losses, improving voltage profiles, correcting power factors and increasing system capacity in power distribution systems.
Voltage deviations from the nominal value were significantly reduced. There was a notable reduction in active power losses (I2R losses) throughout the distribution lines. The optimized capacitor placement minimized the current flow, thereby reducing resistive losses.
Distribution systems commonly face issues such as high power losses and poor voltage profiles, primarily due to low power factors resulting in increased current and additional active power losses.

Environmental factors such as temperature and humidity can have a significant impact on the performance and lifespan of capacitors. High temperatures can cause the capacitance value to decrease, leading to a loss of functionality. Similarly, excessive humidity can result in the formation of moisture inside the capacitor, which can lead to short circuits and failure.
