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.

Coil Analyzers & Power Supplies
-
Coil analyzers and power supply units are portable and lightweight devices intended for use in harsh switchyard and industrial environments. The typical application is switchgear and circuit breaker testing when substation battery is not connected or available. An advantage over substation battery is enabled testing in under-voltage and over-voltage conditions. Furthermore, the stable voltage outputs with a very low ripple (<0,5%) enable an analysis of the coil and motor current graphs recorded with circuit breaker analyzers from different vendors.SAT40AD, POB30AD, and POB40AD are unique devices in the market due to their dual purpose:Power supply for coils and spring-charging motorsTesting circuit breaker’s coils, motor, and auxiliary circuitAll DV Power coil analyzers and power supply units have four separate outputs for opening and closing coils.SAT40AD has two powerful motor outputs (AC and DC) which can withstand up to 40 A inrush current.POB30AD and POB40AD have DC motor output rated up to 30 A and 40 A respectively. With the use of motor outputs, POB and SAT can also be used as a power source or a temporary battery charger.SAT40A II series instruments can be controlled via PC. The DV-Win application software is used to control both SAT and CAT (Circuit Breaker Analyzers & Timers) devices at the same time, making a unique test system for switchgear and circuit breaker testing.

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.
