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 .
