DV POWER TWA40D Winding Ohmeter

DV POWER TWA40D Winding Ohmeter

    • Resistance measurement of all tap positions in all
      six windings performed in a single test
    • True three-phase on-load tap changer dynamic
      resistance measurement
    • Extremely quick measurement, single-step cable setup
    • Automatic discharge process
    • Rapid automatic demagnetization
    • Built-in tap changer control unit
    • Additional testing mode, Quick YN, is enabled by the DV-Win software. In this mode, it is possible to measure the resistances of three transformer windings in the YN configuration simultaneously.
    • It is also possible to test the resistances of all tap changer positions of all three phases in a single pass through the tap changer positions.
