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 |
11 |
Over current protection unit integrated in software and hardware |
12 |
Upload the test results to PC by RS232 and make word report by software |
