- 繞組電阻測量:
-
- Test currents 5 mA – 100 A DC (depends on model)
- On-load tap changer dynamic resistance measurement
- Three resistance measurement channels
- Four temperature measurement channels
- Vibration measurement
- Automatic resistance/temperature measurement for the Heat Run test
- Rapid automatic demagnetization
- Tap changer motor current monitoring channel
- Automatic discharge circuit
- Three models: RMO40TT, RMO60TT, RMO100TT
- 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
- Measurement of on-load tap changer external tank vibrations using an accelerometer
- Heat Run test, which enables obtaining the Hot Spot temperature along with temperature/resistance graph during the cooling process
- A single-phase automatic transformer demagnetization
- System Overview:
- The Tap Changer Analyzer & Winding Ohmmeter of the RMO-TT series is designed for winding resistance measurement of inductive objects, and for a tap changer analysis.
- The RMO-TT instruments are accurate (0,1%), powerful (up to 100 A) and still portable.
- The Instruments generate a true DC ripple free current with automatically regulated measurement and discharging circuit.
- RMO-TT instruments can perform a simple, quick and reliable transformer on-load tap changer condition assessment.
- This series of instruments enable 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 application 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.
- The standard interface is USB. RS232 is optional.
