- Automatic resistance measurement
- Heat Run test
- Rapid automatic demagnetization
- Tap changer motor current monitoring channel
- Automatic discharge circuit
- Built-in tap changer control unit
- Three models: RMO25TD, RMO40TD, RMO60TD
- Application:
- Three-channel winding resistance measurement, which enables simultaneous winding resistance measurement of up to three windings on a single phase
- Dynamic resistance measurement (DVtest) of on-load tap changers, performed on a single phase
- A measurement of on-load tap changer motor current by using a dedicated channel
- Heat Run test, which enables obtaining the Hot Spot temperature along with resistance graph during the cooling process
- A single-phase automatic transformer demagnetization
- System Overview:
- The Tap Changer Analyzer & Winding Ohmmeter of the RMO-TD series is designed for winding resistance measurement of inductive objects, and for a tap changer analysis.
- The RMO-TD series is accurate (0,1_%), powerful (up to 60 A) and lightweight.
- It generates a true DC ripple free current with automatically regulated measurement and discharging circuit.
- RMO-TD series can perform a simple, quick and reliable transformer on-load tap changer condition assessment.
- This series enables measurements of a winding resistance in every tap position, current ripple values (percentage of a current drop during a tap change) and transition times during the tap changes. Problems with a connection, contacts, and selector/diverter switch operation (tap change with interruption) can be detected with these measurements.
- DV-Win software:
- The 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.
- The software provides an OLTC (tap changer) condition assessment through analysis of the graphs representing dynamic resistance values during the tap changer transitions.
- Additionally, the DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation.
- It also enables the recording of tap changer motor current, which is used for detecting motor and mechanical problems.
- The software can also perform the calculations necessary for the “Heat Run” test.
