Abstract :
The paper introduces the measuring grounding resistance principle of the method of selective electrode and frequency conversion, on the basis of which it also designs the variable frequency grounding resistance detector based on ADSP_BF504, which adopts the DDFS technology and the transformation frequency measurement technology based on the fast Fourier transform to measure grounding resistance, and fixes the fast Fourier algorithm by using the interpolation algorithm with window to complete the biggest interference frequency measurements. And for its performances of automatic frequency selecting, reducing leakage, and inhibit clutter or noise interference, it can achieve the purpose of grounding resistance accurate measurement.
