Single-Phase Transformer Winding Resistance Meters
RMO-TW Series
-
RMO-TW series is perfect for winding resistance measurements of inductive objects. It is ideal for testing transformer windings (power transformers, distribution, autotransformers) and for on-load tap changer verification. In addition, any RMO-TW transformer ohmmeter & tap changer analyzer can also perform transformer demagnetization.The series contains 4 models, with maximal test currents from 10 A (RMO10TW) to 50 A (RMO50TW). They are fitted in a portable and lightweight metal housing.All transformer ohmmeters from RMO-TW series generate a true DC ripple-free current with automatically regulated measurement and discharging circuit. The injection of current and discharge of energy from the test object are automatically regulated.Three independent channels enable testing of three windings in series. Consequently, this enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.DV-Win software 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. Finally, a user can export all results in the form of a report.

Three-Phase Transformer Winding Resistance Meters
TWA Advanced Series
-
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.

Current Transformers
-
The Institute of Electrical and Electronic Engineers defines a current transformer (IEEE Std C57.13) as “a transformer intended to reproduce in its secondary circuit, in a definite and known proportion, the current of its primary circuit with the phase relations substantially preserved”. Its primary winding is connected in series with the conductor carrying the current to be measured or to be controlled and its secondary winding is connected to the measuring, protection or control devices. Osborne designs and manufactures current transformers which are used for instrumentation applications, others which are used for power system synchronizing applications and others which are used in protection circuit application. They have been designed to meet specified current ratios, burden impedance and transformation errors.
