Single-Phase Transformer Winding Resistance Meters
RMO-TD Series
-
Using the most advanced switch-mode technology available today, the RMO-TD series is ideal for winding resistance measurements of inductive objects. Transformer resistance meters and tap changer analyzers are perfect for testing:transformer windings (power transformers, distribution, autotransformers),all types of tap changers,generators,electrical motors,high-current busbar joints,cable splices,and welding joints.In addition, transformer demagnetization can also be done with all RMO-TD instruments.The RMO-TD series contains 3 models, with maximal test currents from 25 A (RMO25TD) to 60 A (RMO60TD).The three independent voltage sense channels enable testing of three windings in series. This enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.All RMO-TD transformer resistance meters have a built-in tap changer control unit. It enables remote control of on-load tap changer (OLTC) directly from the device. In order to make the most out of this feature, DV-Win software is included which can be programmed 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.

Auto Transformers
-
Osborne often recommends Auto Transformers in situations where reducing physical size of the transformer is advantageous. Auto transformers offer size advantages when compared to equivalent isolation transformers. Auto transformers provide lower levels of regulation than the equivalent isolation transformer. Osborne helps our clients accommodate for the loss of regulation while achieving the physical size (and cost) advantages of auto transformers.

Step Up Transformer
MagD
-
SCOPE proudly introduces Step-Up Transformer - MagD, specially designed to cater the needs of testing of instrument Transformers. Before new systems are put into service or after any occurrence of fault, the instrument transformers need to be tested for their outputs. It is to be ensured that these instrument transformers are giving proper outputs to the protective relays. MagD is used to plot excitation curves for instrument transformers. Inbuilt voltmeter and ammeter, eliminates the need of external meters for plotting of curves. It can also be used for de-magnetization of transformer cores and also turns-ratio tests can be conducted using MagD.

Injection Transformer
J2101A
-
The injection transformer is presently the prevalent method for connecting the network analyzer to the circuit being tested, and is primarily used for control loop stability measurements. The goal of the transformer is to inject a signal into the control loop being measured, without impacting the performance of the loop. In order to accomplish this to a reasonable degree, The transformer is isolated and therefore is capable of floating on a high voltage, such as a Power Factor Corrector (PFC), which is often close to 400VDC. Measuring voltages that exceed the voltage rating of the FRA inputs require attenuation probes.
