Study on Testing Method of Non-polarized Electrode

Abstract

The observation of geoelectric field in the field data acquisition of electrical prospecting is usually achieved by the use of non-polarized electrodes. The performance of non-polarized electrodes directly affects the quality of field data. The existing non polarized electrode is usually used to evaluate the initial range and the stability of the electrode. In order to make a further evaluation, an indoor and field test scheme is developed. In the laboratory, three parameters, such as the extreme stability, the source impedance and the background noise level, are tested. The field test is carried out from the following two aspects: the parallel consistency test and the MT test. The results show that the above parameters and the field test results show that the electrode can be used for field MT data acquisition. It provides a scientific and feasible test scheme for the full evaluation of the non-polarized electrode test.
