Based on HHT Grounding Grip in the Application of On-line Monitoring

In order to more conveniently and accurately monitoring the real-time parameters of grounding grid, this paper based on potentiostatic method of grounding grip of corrosion state and electrical performance monitoring principle. Hilbert-huang transform(HHT) is suitable for nonlinear and non-stationary signal analysis, the analysis of received signals by empirical mode decomposition and Hilbert spectrum. Then make the use of MATLAB to achieve the simulation diagram, and compare the historical record files, so as to realize the grounding grip of on-line monitoring.
