Resistance Measurement
PROMET
-
High-precision micro-ohm measuring systems with adjustable DC test current for determining resistances on circuit breakers or inductive loads such as transformers, for example. The high-precision ohm meters of the PROMET series are used to determine very low electrical resistances in the µΩ range. The adjustable test current of up to 600 A in combination with a four-wire measuring method delivers measurement results which meet stringent accuracy requirements. State-of-the-art power electronics coupled with a robust design guarantee excellent reliability for use as a portable device in switching stations and industrial environments. Typical applications include determining the contact resistance of switchgear devices and determining the resistance on inductive loads such as transformers.

Transformer Winding Resistance Meters
RMO TT Series
-
The Tap Changer Analyzer & Winding Ohmmeter of the RMO-TT series is designed for winding resistance measurement of inductive objects, and for a tap changer analysis. The RMO-TT series is based on the state of the art technology, using the most advanced switch mode technology available today. The RMO-TT instruments are accurate (0,1%), powerful (up to 100 A) and still portable. The Instruments generate a true DC ripple free current with automatically regulated measurement and discharging circuit. RMO-TT instruments can perform a simple, quick and reliable transformer on-load tap changer condition assessment. This series of instruments enable measurements of a winding resistance in every tap position, current ripple values (percentage of a current drop during a tap change) and transition times during the tap changes. Problems with a connection, contacts, and selector/diverter switch operation (tap change with interruption) can be detected with these measurements.

Integrity Design and Reseach Corp.
Two cylindrical tubes are equal in length (12"), one is inside the other, both of them are closed at one end. At the other end, the inner tube is open (Radius=1").The cylindrical tubes are made from high permeability material.The magnetic field inside the inner tube is almost annulled.Optional use with the Geomagnetometer IDR-321 to provide a zero gauss (magnetic field-free environment) reference, enabling you to take absolute readings of the ambient magnetic field (the Earth's magnetic field is typically around 500 mG)

New Resistivity Inversion Software
EarthImager 3D
-
AGI is proud to introduce the new EarthImager 3D resistivity and IP inversion software. This software inverts resistivity and IP data acquired with electrodes arranged in boreholes and/or on the surface and presents a 3D volume of inverted resistivity data with advanced volume rendering technique. The final resistivity or IP image-volume can be rotated in any orientation, zoomed in and out, and translated to anywhere inside the image window in order to see the volume of interest in detail. Colors representing areas of less interest can be made transparent so that the shape of a pollution plume, for example, can be visible. With EarthImager, 3D resistivity inversion can be as easy as two steps: Read Data and Start Inversion with only a few mouse clicks.

Resistivity Meter with Multi Electrode
POLARES
-
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.
