Micro-Ohmmeters
RMO-G Series
-
The RMO-G is a portable micro-ohmmeter designed for contact resistance measurement of non-inductive test objects and applications with increased safety requirement. It tests medium and high-voltage circuit breakers, disconnecting switches, high-current bus bar joints, cable splices, and different high-current links. Due to its Both Sides Grounded and Remote Control functionalities, the instrument accurately measures even in the most demanding environments, providing additional safety to testing personnel.The RMO800G is the most powerful portable micro-ohmmeter on the market with 800 A output current. RMO200G is our best seller in the USA. A user can choose the appropriate model depending on the output current requirement, from 100 A (RMO100G) to 800 A (RMO800G).We use an unbreakable plastic case with IP67 protective rating (with closed lid) for instruments’ housing. Although very portable and lightweight, RMO-G micro-ohmmeters have very high output power capabilities. High output voltage enables a wider measurement range at higher test currents. Consequently, it enables the usage of thinner/longer test cables. RMO-G generates a true DC ripple-free (less than 1 % ripple) current with automatically regulated test ramps. During the testing, it increases current before measuring and decreases current after the measurement. This significantly decreases magnetic transients and ensures great accuracy.Special current clamps measure a current through groundings when the instrument tests in Both Sides Grounded conditions. The instrument itself powers these clamps. If even higher safety level is required, the Remote Control feature enables the operator to perform measurements from distant locations.RMO-G instruments can store up to 500 measurements in internal memory. Also, they have a built-in thermal printer and USB flash drive available as an option. An additional option is the built-in High Precision module suitable for measurement of very low resistance, in the range from 1 to 30 µΩ, with 0,01 µΩ resolution.Our free DV Win software communicates with the RMO-G micro-ohmmeters via USB or RS232 interface. It allows a user to run the test remotely from a PC. Also, a user can download test results, analyze and generate fully configurable test reports through the software.

CAT Advanced Series
-
DV Power circuit breaker analyzer and timer utilizes the latest technological enhancements for safe and fast testing of circuit breakers. The sophisticated design ensures efficient and reliable operations in high-voltage substations and industrial environments.The CAT Advanced series are stand-alone or PC-controlled digital instruments for a circuit breaker testing. The timing channels record closing and an opening of the arcing, resistor, and auxiliary contacts. Also, the main contact channels can measure the resistance value of the pre-insertion resistors (if present in the circuit breaker).With CAT Advanced series instruments, it is possible to record graphs of open and close coil currents. Furthermore, it records displacements of the HV and MV circuit breaker moving parts. Test results can be saved via USB, PC or be printed via 112 mm (4.4 inches) thermal printer (optional accessory) in tabular and graphical form.A circuit breaker test consists of different operational modes and CAT Advanced series supports:Open (O)Close (C)Reclose (O-0,3s-C)Trip free (CO)O-0,3s-COOpen-Close (O-C)Close-Open (C-O)Open-Close-Open (O-C-O)First trip (O)Multiple operations, such as Open-Close and Open-Close-Open, can be initiated by using a predefined delay time or by sensing a breaker’s contact position.The auxiliary inputs are used to monitor dry and wet auxiliary contacts. The six coil control analog channels measure and record coil currents simultaneously (OPEN and CLOSE), up to 35 A AC/DC.The additional six voltage analog channels have four selectable voltage ranges available (±1 V, ±5 V, ±60 V and ±300 V AC/DC).A built-in micro-ohmmeter generates up to 500A true DC ripple-free current with an automatically regulated test ramp that provides performing static and dynamic contact resistance measurement.Three transducer channels provide a measuring displacement of the circuit breaker moving parts, contact wipe, over-travel, rebound, damping time and average velocity. Also, a user can connect either an analog or a digital transducer to these universal channels.

During a test, the protective bonding testers automatically generate increasing current before measuring and decreasing current after the measurement. Consequently, this significantly decreases magnetic transients and ensures great accuracy.These instruments can store up to 500 measurements in the internal memory and have a built-in thermal printer available as an option.DV Win software communicates with the RMO-E earth resistance meter via USB or RS232 interface. It allows a user to run the test remotely from PC, as well as to download test results, analyze and generate fully configurable test reports.The RMO-E series contains two models, RMO60E and RMO100E.

Single-Phase Transformer Winding Resistance Meters
RMO-TD Series
-
Using the most advanced switch-mode technology available today, the RMO-TD series is ideal for winding resistance measurements of inductive objects. Transformer resistance meters and tap changer analyzers are perfect for testing:transformer windings (power transformers, distribution, autotransformers),all types of tap changers,generators,electrical motors,high-current busbar joints,cable splices,and welding joints.In addition, transformer demagnetization can also be done with all RMO-TD instruments.The RMO-TD series contains 3 models, with maximal test currents from 25 A (RMO25TD) to 60 A (RMO60TD).The three independent voltage sense channels enable testing of three windings in series. This enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.All RMO-TD transformer resistance meters have a built-in tap changer control unit. It enables remote control of on-load tap changer (OLTC) directly from the device. In order to make the most out of this feature, DV-Win software is included which can be programmed to do everything automatically – running winding resistance tests and changing OLTC tap positions.The DV-Win software also 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.All results can be exported in the report format.

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.
