Cable systems for electrical surveys

... connector  “cable  system  –external  electrode”   with  “alligator”  or RPT-21 clips. There is  no  need  to  use external  electrodes  when surveying  on  water areas  and  boreholes, because the surface area of electrodes in cable systems has low contact resistance in such conditions. Different  amount  of  electrodes  can  be  designed  at  the  cable  system  on  demand  (24/32/48),  as  well  as different  electrode  spacing  and  passive  ending  of  ...

Cable systems connector

The connector is used to connect the sections of electric or seismic survey cable systems into a single line. At a significant step between the points of electrodes / seismic receivers connections, the total length of the receiving lines, their mass and dimensions in a folded state make the work inconvenient. The use of connectors ...

ZondCHT - 2.5D electrotomography for cross-borehole resistivity and IP

... – high-resolution electric prospecting method. Taking into account that at each position of the source the certain part of the section influences on results of measurements in a greater degree, we can say that at a successful choice of observation system (number of measurements, a spacing between electrodes of cable, electrodes array) it is possible very detailed estimation of parameters distribution in cross-borehole space. The software-hardware-methodical complex for processing of cross boreholes works essentially differs from the land analog. It requires ...
