The industrial sector is trying to make the system faster. For system efficiency and regulation, new technologies play an essential role. The average industry possesses 80% of inductive load and has a lagging power factor. The use of power electronic devices in the system causes power quality disturbances. Nowadays, the electricity demand is increasing, and it is necessary to supply/serve power with good quality. The inductive load is responsible for reducing the power factor. Power factor improvement capacitors are used in the system. But during the switching of capacitors, current transients are produced in the design and lead to damage to capacitor bank and power electronic devices.

This paper proposed a design and case study of the inrush current transients and phenomena using MATLAB simulation.
