POLARES -
PASI srl
Till this moment the use of Electrical Resistivity Tomography (ERT) for geology has always been basically the same since its debut, based on the original vertical Electrical Soundings (VES) principles: applying a continuous current to two stakes inserted into the ground and measuring the corresponding voltage between other two. The applied current and thus the relative tension have always been continuous, with an inversion in polarity for each measure. The new tool POLARES uses an alternate current, instead, sinusoidal type, with an adjustable frequency.

HFCT Ø 140mm -
Techimp HQ S.r.L
Techimp Clamp High Frequency Current Transformer model 140 is an inductive sensor for partial discharge measurements. It is suitable for online /off line PD tests on : large diameter cables ; grounding rod bar ; etc. A TNC termination is available to connect the Clamp HFCT 140 to the TechImp PD analyzer : PDCheck , PDBase etc. The arrow indicates the requested input current (Iin) direction to get coherent output voltage (Vout) polarity respect to ground. When the sensor is installed with the arrow directed to ground, the detected voltage signal (Vout) has the same phase of the input current (Iin).
