Bulk Current Monitoring Probe
MP-50
The Current Monitoring probes may be used whenever RF current measurements are required. Current measurements are made by placing a current carrying conductor within the “sensing” window of the probe and measuring the probe’s output voltage with an RF detector. Calibration of the probe permits the conversion of the voltages measured to current. Current measurements can be made over the frequency range shown in the transfer impedance curve furnished with each probe. There is virtually no loading of the circuit and the technique permits normal operation of the device under test during measurements. The MP-50 can be used for the procedure for clamp injection when the common- mode impedance requirements cannot be met given in chapter 7.4 of IEC/EN 61000-4-6 „Immunity to conducted disturbances, induced by radio frequency fields”. The MP-50 can also be used as current monitor for BCI testing as per ISO11452-4, RTCA/DO-160 section 20, MIL-STD-461 and various automotive standards.

Single-Phase Transformer Winding Resistance Meters
RMO-TT Series
RMO-TT series is perfect for measuring winding resistance of inductive objects such as power and distribution transformers or autotransformers. Additionally, every transformer resistance meter from RMO-TT series can analyze:tap changers,generators,electrical motors,high-current busbar joints,cable splices,and welding joints.Transformer demagnetization can also be performed with all RMO-TT instruments.The series is consisted of 3 models, with maximal test current from 40 A (RMO40TT) to 100 A (RMO100TT). RMO100TT is the only portable transformer resistance meter in the market with 100 A DC output current.The three independent channels enable testing of three windings in series. Consequently, a user can measure winding resistance in every tap position of an on-load tap changer without discharging between the tests.In addition to winding resistance measurement, a user can perform a detailed on-load tap changer analysis by analyzing recorded graphs (10 kHz sampling rate) and by measuring vibrations on an external tap changer tank.All RMO-TT instruments have a built-in tap changer control unit. Because of this, it is possible to remotely control on-load tap changer (OLTC) directly from the device. Also, a user can program DV-Win software 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.
