Product description

GDBC-901 High Voltage Transformer Turns Ratio Tester , TTR Meters

The Automatic Transformer Turn Ratio TTR Tester is designed to measure the turns ratio of power, instrument, and distribution transformers in a substation or manufacturing environment.

It weighs (<7 KG) less than most commercially available instrument. A rugged and robust design makes this TTR test set well suited for use in a variety of harsh environments.

The phase transformer turn ratio tester is also particularly suited for testing in power transformer manufacturing environments where testing of complex, three-phase substation power transformers can be performed quickly while minimizing the possibility of errors.

I. Functions of TTR meter

1

The voltage ratio measurement for three or singe phase transformer

2

The group vector measurement for three phase transformer.

3

The polarity measurement for single phase transformer or CT/PT

4

Voltage ratio error calculation

5

Current transformer ratio measurement

6

Excitation current measurement in ratio testing

7

Reproduction the AC test voltage from power source to reduce the effects of bad power source

8

Save the test results in the memory internal the tester

9

Print the test results by micro printer

10

Reverse connection detect unit to prevent the high voltage injected to operator
