Evaluation of parasitic resistance in voltage-driven electrical resistance tomography

Abstract: Electrical resistance tomography (ERT) is an effective method for monitoring electrical conductivity distribution in the field using boundary measurement information. In applications with a large pipe diameter and large load variation, voltage-driven ERT (ERTv) can overcome the limitations of current-driven ERT (ERTc). A voltage source is used in ERTv to apply an excitation signal to the electrode, and can provide a large output signal. Meanwhile, saturation will not occur when the load of the field shows larg… Show more
