RMO-E Series -
IBEKO Power AB
The RMO-E instruments are designed and ideal for testing protective bonding (grounding) of equipment following the standard IEC 61010-1. Also, they can measure the resistance of high, middle and low voltage circuit breakers, high-current bus bar joints, cable splices, and welding joints. The instruments accurately measure not only in factory environments but also in high-induction fields and substations.Both models generate a true DC ripple-free (less than 1 %) current with automatically regulated test ramps. 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. The main difference between these two models is in the maximal test current:60 A DC for RMO60E100 A DC for RMO100E

TWR-H Series -
IBEKO Power AB
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.
