Abstract :
The detection system for harmonic is designed in this paper. The adopted microchip is LPC1114 with the built-in A/D device. The high precision signals of current and voltage are sampled by using the A/D device. The sampling data is analyzed by the windowed interpolation FFT algorithm. And the frequency and amplitude of fundamental and harmonic wave for the current and voltage is got. The test results prove the virtues of this system with the simple hardware and the high precision.
