Description

DTBZ-2009 is an enhanced Transformer Turn Ratio Tester. It is capable to test single-phase and three-phase transformers. The testing process is fully automatic and very quick.

Another important function is automatically measuring the vector group of transformers.

Operator enters the test parameters, DTBZ automatically performs the testing process: Power up the test voltage, Balance the test bridge, Take the readings and Display on the LCD screen, then Print the results on built-in printer.
