DV Power TWA500 Transformer Winding Resistance Analyzer

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
