Why we must install capacitor in parallel to inductive load? Why not install it in series?
Voltages across the inductive load and the capacitor will be equal since they are in parallel. But the capacitor voltage may not be equal to the source voltage as there can be some resistance in between the source and the inductor.FionaZJ said:Is it capacitor will draw all the voltage source in parallel?
Yes. The inductive magnetising current will be stable when running. The power factor correction capacitor will have the full supply voltage across it so it will cancel most of the inductive component. The real load will have the full supply voltage across it.FionaZJ said:So if we install capacitor in parallel, there will be full voltage supplied available?
I think jaus tail is writing about neutralisation of regional transmission lines while I am writing about neutralisation of local electric motors.jaus tail said:Not really. The transmission line will have inherent inductance, resistance, and capacitance which depend on:
length of line
proximity to other conductors
whether ac or dc voltage
So voltage across load is source voltage minus the transmission line voltage drop.
Power factor correction is the process of improving the overall power factor of an electrical system. This is achieved by adding a capacitor in parallel with an inductive load, which helps to balance out the reactive power and increase the efficiency of the system.
Power factor correction is important because it helps to reduce energy waste and improve the efficiency of an electrical system. A low power factor can result in higher energy bills and strain on the electrical grid, so correcting it can save money and reduce environmental impact.
When a capacitor is added in parallel with an inductive load, it creates a capacitive reactance that offsets the inductive reactance of the load. This helps to balance out the reactive power, resulting in a higher power factor and improved efficiency.
Any load that has a high inductive component, such as motors, transformers, and fluorescent lighting, can benefit from power factor correction. These types of loads can cause a low power factor and waste energy without correction.
The correct size of a capacitor for power factor correction can be determined by calculating the reactive power of the load and the desired power factor. This calculation can be done using a power factor correction calculator or consulting with a qualified electrician.
