Earth-electricity Model of High Voltage DC Landfill Leakage Detection

摘要：

The method of high voltage DC in landfill leakage detecting is widely accepted in many developed countries, but the theory of this method is trailed its application. In the earth-electricity model of the high voltage DC method, there will be formed a conductive membrane similar to PN junction, and make the model possess commutated character at the contacted surface, because of the full contact between the HDPE (High Density Polyethylene) liner and the earth. In this paper, the formation of the electrolytic capacitor and its conductive mechanism will be fully discussed by experimental analysis, and point out the capacitance increases as the liner area and supply power increases. The equivalent circuit of high voltage DC method about the earth-electric model is pointed out. The simulated physics test demonstrated the electrical characteristic of the equivalent circuit is same to the landfill.
