WDA-1 work with WDZj-4 or WDZJ-120 Multi Electrode Switcher can be applied in a variety of complex regions and has widely used in metaland non-metal mineral resources prospecting, city geophysical exploration, andrailway and bridge inspection; in hydrology and engineering geology to inspectbase of dam and flood protection levee for incipient faults. Besides, it contributes to geothermal survey.
a). General resistivity/IP survey, in association with only one/two Current electrodes, one/two Potential electrodes, AB connecting wire, MN connecting wire and power source. For this part, please refer to Section Three and Section Four)
b). Multi-electrode 2D resistivity imaging when works together with WDZJ-4 Multiple Electrode Converter, power source, electrodes and corresponding cables. For this section, please refer to Section Six.
c). Multi-electrode 2D resistivity imaging (in Section Seven), Multi-electrode 3D resistivity imaging (in Section Ten) and Multi-electrode 2D induced polarization (IP) imaging (in Section Nine), in association with 10-take-out intelligent cables, electrodes and power source.
16 kinds of electrode arrays of multi-electrode system:
In addition to the 10 electrode arrays of general electrical resistivity survey system
There are 16 electrode arrays for multi-electrode imaging, namely, Wenner Alpha array (WENNER α), Wenner Beta array (WENNER β), Wenner Gamma array (WENNER γ), Three-pole direct array (δA ARRAY), Three-pole reverse array (δB ARRAY), Wenner Alpha 2 array (SCHLMBG), Self-Potential M array (SP-M), Self-Potential MN array (SP-MN), Charging M (CHG-M), Charging MN (CHG-MN), Two-pole Roll along array (2P AM), Three-pole Roll along array (3P A-MN and 3P AB-M), Dipole-dipole Roll along array (DIPOLE), MN-B, Cross-Hole Dipole/Equatorial Dipole-dipole array (CR-DIPOLE).
