Paper Title
Power Quality Monitoring Using FFT Algorithm With FPGA Based Processing

This paper presents three phase power meter for measuring electric parameters where 256 point FFT is implemented. As there is increase in high speed nonlinear loads, Power Quality monitoring cannot be ignored, considering to this require a meter with higher accuracy and computation. The design is based on FPGA processing where it is used because of its performance and flexibility and also ability to meet speed and update system functionality. Micro controller is used to control circuits of analogue part, display the values, communication with components via RS 422 interface.
