Product Description

GDHG-106B Current Transformer and Voltage Transformer Analyzer



General introduction

GDHG-106B is a multifunctional tool specially designed for analyzing current transformers and voltage transformers of protection or measurement use. The operator only needs to set values for test current and voltage, the instrument will automatically boost voltage and current, and then show test results in a short time. Test data can be saved, printed, and uploaded to PC through USB interface.


Features

1. Finish all testing subject by itself, no need to connect auxiliary equipment.

2. Built-in printer, to print results easily.

3. Large screen LCD, graphically display.

4. Auto display excitation knee point value, 5% and 10% error curve.

5. Save 3000 groups data.

6. With USB port. The data can be saved in USB disk and read by PC(WORD format file).

7. Portable design about 35kg, suitable for on-site test.

8. Engineering plastic box with damping, strong and reliable.
