Electra is composed of a central unit (2 kg, rechargeable battery

included) to be connected to any PC and of a very light cable along

which the small moduli to be connected to the electrodes are attached.

Each module has the double function of injecting current in the subsoil

and of receiving the signal, by amplifying and digitizing it directly at the

source (the electrodes). The signal is then transmitted to the central

unit in a digital form through the very simple, light and high performing

main cable, which prevents any cross-talk and signal degradation

phenomenon.

 

 

Electra can inject any current in the subsoil (from continuous to

alternate) at different frequencies. Measurements in alternate current

are faster and more precise, since no time is needed for the signal

stabilization and induced polarization of the electrodes is minimized.

The possibility to inject different waveforms also opens the way to new

studies on the relations between the energization procedures and the

subsoil response.
