Demo Setup

Using the ADE9078, our group created a PCB and wrote firmware to create a small portable three phase wattmeter. Our demo setup was designed to detect faults in a three phase motor. By performing a Fast Fourier Transform (FFT) on the power data and looking for irregularities, we were able to determine if the motor was faulty.

My primary contribution was configuring the waveform buffer firmware and creating a graphical interface for FFT.
