Single-Phase Transformer Winding Resistance Meters
RMO-TW Series
-
RMO-TW series is perfect for winding resistance measurements of inductive objects. It is ideal for testing transformer windings (power transformers, distribution, autotransformers) and for on-load tap changer verification. In addition, any RMO-TW transformer ohmmeter & tap changer analyzer can also perform transformer demagnetization.The series contains 4 models, with maximal test currents from 10 A (RMO10TW) to 50 A (RMO50TW). They are fitted in a portable and lightweight metal housing.All transformer ohmmeters from RMO-TW series generate a true DC ripple-free current with automatically regulated measurement and discharging circuit. The injection of current and discharge of energy from the test object are automatically regulated.Three independent channels enable testing of three windings in series. Consequently, this enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.DV-Win software enables control and observation of the test process, as well as saving and analyzing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. Additionally, DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation. The software can also perform the calculations necessary for the “Heat Run” test. Finally, a user can export all results in the form of a report.

Loop Resistance Measuring Device According to DIN EN 61557-3 (VDE 0413-3)
-
PeakTech Prüf- und Messtechnik GmbH
A loop tester which is used to test the safety of electrical systems. These device measures the impedance of the short-circuit loop between the outer conductors of a circuit, whereby the probable short-circuit current is calculated. The protection of the circuit (miniature circuit breaker) must therefore trigger at a lower current than the expected short-circuit current, in order to avoid excessive heating of the lines and thus a fire risk. The PeakTech 2715 is due to its function and its robust design almost indispensable when performing new installations, but also for general checking of electrical systems, this device is the ideal companion.

4-Wire Resistance Measurement | Continuity & HiPot Cable & Wire Harness Testers
-
An add-on option for the CableEye HVX high voltage cable tester series that permits expanded testing for contact and wire resistance as low as 1 mΩ. After checking for opens, shorts, miswires, and resistance limits, the 4-wire Kelvin measurement applies a user-selectable test current from 10 mA to 1 A to determine connection resistance within 1 mΩ. The resistance profile of a model cable may be stored and used as a basis of comparison during later testing to reveal cold solder joints, faulty crimps, recessed pins, pin contact contamination, improper wire gauge, and stress-extruded wire.This option may be purchased with any new HVX tester, or added as an upgrade to any of your existing HVX testers.

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.

Resist Processing Systems
-
The EVG100 series resist processing systems establish new standards in quality and flexibility for photoresist coating and developing. Designed to provide the widest range of process variations, the EVG100 series’ modularity offers spin and spray coating, developing, bake and chill modules to suit individual production requirements. These systems accommodate the processing of an extensive range of materials such as positive and negative resists, polyimides, double-sided coating of thin resist layers, high viscosity resists, and edge protection coatings. These systems can handle more than one substrate size, from 2" to 300 mm diameter, rectangle, square or even irregular shaped substrates, with no or very short tooling time. This allows the development of new devices or processes on an industrial level, which not only requires high flexibility but also controlled and repeatable processing. EVG has built up many years of spin and spray coating experience for demanding applications and incorporates this knowledge into the EVG100 series, where our process know-how can be leveraged to support our customers.

Resistance Grounded Systems (HRG/LRG)
-
Neutral Grounding Resistors (NGRs) are used to limit the maximum ground-fault current. Restriction of fault current lowers hazards and reduces damage done to equipment. High Resistance Grounding (HRG) systems are often used on industrial and critical power applications to maintain system uptime during a first ground fault. HRG systems are also used in tripping applications to help control touch potential on portable loads and improve personnel safety.

Handheld Turns Ratio & Winding Resistance Tester
TWR-H Series
-
Handheld TWR-H device is DV Power single-phase instrument designed for measuring transformer winding resistance and turns ratio.The instrument has two output DC sources for measuring transformer winding resistance. The first DC source can output up to 2 A DC and is used for injecting current to the transformer’s high voltage winding. The second DC source can output up to 10 A DC and is used for testing the transformer’s low voltage winding. This is especially useful when measuring winding resistance of distribution transformers. These transformers have large turns ratio and therefore a big difference between resistances of high voltage and low voltage windings. Upon the winding resistance test, it is also possible to demagnetize the transformer core. The demagnetization process is completely automatic and safe.Together with the turns ratio, the instrument also measures excitation current and phase shift. This enables detecting transformer core or winding turns failures which cannot be spotted by measuring turns ratio only. The instrument can output test voltage up to 40 V AC for this test, but it can also output a very low test voltage of 1 V AC which is necessary for turns ratio verification of the majority of current transformers.TWR-H is powered by an internal Li-Ion battery. Up to 100 tests can be performed with a fully charged battery.
