PROJECT DESCRIPTION

The project is designed to reduce the power loss in industries by power factor compensation through a number of shunt capacitors. This results in reduction in the amount of electrical bill for industries and commercial establishments.

In this proposed system, two zero crossing detectors are used for detecting the zero crossing of voltage and current. The Time lag between the zero voltage pulse and zero current pulse duly generated by suitable operational amplifier circuits in comparator mode are fed to two interrupt pins of the microcontroller.

It displays time lag between the current and voltage on an LCD. The program takes over to actuate appropriate number of relays from its output to bring shunt capacitors into load circuit to get power factor till it reaches near unity.

A capacitor bank and relays are interfaced to the microcontroller using a relay driver. Microcontroller used in this project belongs to 8051 family.

Furthermore, this project can be enhanced by using thyristor control switches instead of relay control to avoid contact pitting often encountered by switching of capacitors due to high in rush current.

Q & A
Q:  Which microcontroller is used in this project?
A:  The microcontroller used in this project is a 40 pin IC from 8051 family.
Q:  Which inductive load is used in this project?
A:  A 40 W tube light choke is used in this project.
Q:  Can I replace choke by induction motor?
A:  Yes, the choke can be replaced by induction motor.
Q:  Why is the lamp used in series with the inductor?
A:  A lamp is used in series with the inductor, because a standard 40 watt tube light choke cannot be directly connected to mains.

I was searching for the final projects for electronics in google. I got the edgefx link through that i have contacted the edgefx kits & solutions. Keywords i used electronics final year projects.
There was no other option for me to go that is why i purchased project for edgefx. I like kit presentation.
the was delivered on time with right components
customer service has helped me in purchasing the project
Everything was good.
i gave reference to my friends
