    Product Description

    GDB-Transformer Turns Ratio Tester is specially designed for three-phase transformer in power system, especially for transformer of type Z winding and other transformers whose zero-load current is relatively high.

    The tester has wide testing range, fast testing speed, favorable repeatability, flexible data processing, convenient connection, complete protection, easy learning and convenient operation.


    Features

    • Applicable to transformers connected in Z type.
    • Two output voltages are optional and applicable to transformer whose zero-load  current is relatively high.
    • Wide testing range and the highest transformation ratio may reach 10000.
    • Automatically calculate tap position.
    • Fast speed, which is only 18 seconds for three-phase
    • Favorable repeatability.
    • Automatically save 99 data at most.
    • Flexible data processing, including retrieval, print, transfer to U-disk, delete and 
    • upload to PC computer for testing.
    • Functions of transformer short-circuit protection and interturn short-circuit 
    • Protection functions. If there is short circuit, relevant information will be displayed on the LCD screen.
    • Small size and light weight.
