KVBB-II Transformer Turn Ratio Tester is used to check turn ratio of transformer,  tap switch situation, whether transformer interturn is short circuit and transformer can run in parallel or not . The tester adopts three-phase precision inverter power. It is fast measurement and Easy Operation .

Features

  • Wide measurement range, the ratio measurement can be up to 10000;
  • 7 inch colorful large LCD screen can be displayed clearly in the sunlight .
  • With high and low voltage reverse connection protection and short circuit protection,tap-changer protection,output short circuit protection
  • Built-in three-phase digital power supply, it can improve the stability of measurementand eliminate the harmonic effect of main voltage.
  • Fast measurement speed can be completed three phase test in 10 seconds.
  • Applicable to various of transformers, such as rectifier transformer ,Z type transformer  grounding transformer,electric furnace transformer, phase-shifting transformer, balanced transformer,Scott transformer,Inverse Scott transformer.
  • Automatically measure transformer turns ratio, errorvalue and tap-changer points, especially for asymmetric tap-changer points, also can accurately test the position of the transformer tap-changer, can measure up to 99 points of tap-changer
  • With data storage function
  • Thermal printer with fast speed and low noise .
