Description
The TWA500 instruments are designed for six-winding resistance measurement and simultaneous three phase on-load tap changer analysis of both the primary and the secondary transformer windings. This is performed with a single-step cable setup, with test currents of up to 40 A.
Key Features:
- Resistance measurement of all tap positions in all six windings performed in a single test
- True three-phase on-load tap changer DVtest (DRM)
- Extremely quick measurement, single-step cable setup
- Rapid automatic demagnetization
- Fully automated test mode
- Large 10.1?? graphical touchscreen display
- OLTC vibration measurement channel
- OLTC motor current measurement channel
- Interchangeable test leads with True Three-phase Turns Ratio Testers TRT Series
