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.

AC Test Transformer
Shanghai Guantu Technology Co., Ltd.
How the AC test transformer prevents the overvoltage generated by the frequency conversion series resonance test device is a relatively simple problem, but the overvoltage caused by voltage fluctuation is difficult to appear when the overvoltage protection is set. Generally, the overvoltage of the frequency conversion series resonance test device will appear in the frequency sweep stage of the instrument, that is, in the process of finding the resonance point. Those who have used it know that in the process of finding the resonance point of the frequency conversion series resonance test device, the voltage and frequency have a parabola-like linear relationship. By default, the system finds the high voltage, that is, the apex of the parabola as the resonance point.
