Operation is fast and simple. Just press the spring-loaded probes onto the two poles of the battery. After 1.5 seconds, the unit beeps (indicating good contact) and displays the battery voltage and either the number of siemens or milliohms, depending on the knob setting. The display continues to show these numbers after the probes are removed; it resets only when the probes are pressed onto the next battery. The impedance and voltage of any battery between 1.2 and 60 volts can be read. Because of the wide range of voltages, even single low-voltage cells, such as NiMH, can be measured. The manufacturers of some batteries specify impedance in milliohms while other specify in siemens (one divided by the resistance in ohms). This meter will display both types of impedance for any given battery. Accuracy is +/- 2% of the value.

IBEKO Power AB
Contact resistance measurement is one of the most important and common tests during switchgear manufacturing, commissioning and maintenance stages. Besides switchgear testing, the RMO digital micro-ohmmeters are designed for simple, safe and efficient testing of:disconnecting switches,high-current bus bar joints,cable splices,welding joints,and different high-current links in factory and high-induction field environments.All DV Power RMO micro-ohmmeters use Kelvin’s 4-point measurement principle which is the most convenient for very small resistance measurements. The measurements are accurate and in accordance with international standards for AC high-voltage circuit breakers testing (IEEE C37.09 and IEC 62271-100).Starting from 2003, DV Power has been a trend-setter on the market when our first 500 A micro-ohmmeter weighing only 8 kg (RMO500A / CPM500) was released.Currently, DV Power products portfolio includes 16 models, divided into 3 series:13 portable models: RMO-A (6) and RMO-G (7) series.6 handheld models: RMO-H (6) seriesThe instruments generate a user-selectable and ripple-free test current up to 800 A in an automatically regulated test ramp. Test current ramping significantly decreases the influence of the magnetic transients to measurement.

TWA Advanced Series -
IBEKO Power AB
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.

TWA Standard Series -
IBEKO Power AB
When it comes to winding resistance measurement on three-phase power transformers and autotransformers, TWA Standard series offers some of the most technically advanced instruments with LCD display in the market. Both models are capable of testing six transformer windings with a one-time cable connection, as well as three-phase automatic transformer demagnetization. The stored magnetic energy is safely automatically discharged at the end of the test. The built-in tap changer control unit enables automated test mode, where the instrument operates the tap changer without operator input and records winding resistance results based on pre-selected stabilization criteria. This option makes the operator’s job significantly easier.Both models can output test currents from 5 mA to 25 A DC for the purpose of winding resistance measurement. TWA40D has a special test mode for checking the synchronization of on-load tap changers with three phases simultaneously tested in parallel, in which the total test current can rise to up to 40 A DC.TWA40D has additional advantages when it comes to non-intrusive tap changer analysis. The unique DVtest method 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, simultaneously with the measurement of tap changer motor current which helps with the detection of 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 on three phases simultaneously. It can also be performed as an additional test simultaneously with the winding resistance test in all tap positions.An additional unique advantage of TWA40D 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 shorten the total testing time – for example, it enables the operator to perform 33 measurements instead of 99 on a tap changer with 33 tap positions.The test leads for TWA three-phase transformer winding ohmmeters are interchangeable with the TRT turns ratio testers, which means that both sets of tests can be performed with a single test lead connection to the power transformer terminals.
