Product Description

GDB-D 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.
