Femto / Picoammeter and Electrometer / High Resistance Meter
B2980A Series
-
Both the picoammeters and electrometers provide a world-best performance of 0.01 fA (0.01 x 10-15 A) current measurement resolution. In addition, the electrometers can measure resistance up to 10 P (10 x 1015 ), which is also a best-in-class specification. Finally, since AC power line noise can be difficult to eliminate when making low-level measurements, both the picoammeters and electrometers are available in battery powered versions.

Resistivity Meter
Model 2180
-
The unit is compact and lightweight. The basic system is 7″ wide by 2.5″ high and 12″ long. When measurements are needed below approximately 100 micro-ohm-centimeters, the basic system is piggybacked onto a second enclosure that houses a power amplifier with a current gain of ten. The combined unit measures 7″ wide by 5″ high and 12″ long. The combined unit weighs 11.5 pounds. Two short cables interconnect the two enclosures for powering the power amplifier and routing the signals to the fixture or four point probe. The front panel of the basic system includes a 32-character backlit LCD display and a set of function keys. An easy-to-use menu will allow access to user defined parameters such as sample thickness, sample volume, and calibration constants; upper and lower alarm limits, relative measurements, and several others.

Insulation and Continuity Tester
MIT2500
-
The MIT2500 insulation and continuity tester has been designed for motor and cable testing, specialist applications and electrical testing applications, where operation voltages exceed 1000 V and higher insulation test voltages are needed. The MIT2500 offers both fixed range voltages of 50 V, 100V, 250 V, 500 V, 1000 V and 2500 V, as well as a variable range that allows any voltage between 50 V and 2500 V to be "dialled in". This is supported by the new test voltage feedback control, which maintains the output test voltage to within 2% of the selected range, even when under test.

Three-Phase Transformer Winding Resistance Meters
TWA Advanced Series
-
TWA Advanced series is the latest DV Power solution for three-phase transformer winding resistance measurement and tap changer analysis. They are capable of testing six transformer windings with a single cable connection, as well as three-phase automatic transformer demagnetization. It has the option of the automated test mode, where the instrument operates the tap changer without operator input (minimizing the risk of human error) and records winding resistance results based on pre-selected stabilization criteria.The unique DVtest method of tap changer analysis enables checking the moving contacts of on-load tap changers during the transition, measuring the transition time, detecting open circuits, and many other types of faults. It is performed with 0.1 ms sampling rate, together with the measurement of tap changer motor current which detects motor and mechanical issues. A special proprietary algorithm is used for testing tap changers connected through a built-in series (booster) transformer. The DVtest can be performed either on one phase or simultaneously on three phases. It can also be performed together with the winding resistance test in all tap positions.A unique advantage of TWA Advanced instruments is the capability of simultaneously testing the winding resistance of all three phases of a three-phase transformer connected in a YN configuration. This can significantly speed up the testing– for example, it enables the operator to perform 33 measurements instead of 99 on a tap changer with 33 tap positions.TWA500 is equipped with a large 10.1” graphical touch-screen display, while TWA400 has a 7” graphical touch-screen display. Besides making the interface much more user-friendly compared to older winding ohmmeters, it also enables certain test options that were previously available only with DV-Win software. The most important among them are DVtest, tap changer motor current measurement, “Heat Run” test, test templates, and automatic test mode.

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.
