1. Product introduction

GDBC-901 Full-automatic Turn Ratio Meter is designed according IEC76-1 and IEC60044. The tester could be applied to test the ratio of single or three phase transformer. Also the connection group of three phase transformer could be calculated with the ratio. All parameters are measured in one test for three phase transformer.

2. Main functions and characters

1 Automatically measure transformer connection group

2 Automatically switch range

3 Automatically measure ratio of single or three phase transformer

4 Automatically measure ratio of single or three phase voltage transformer

5 Automatically measure the turn ratio and polarity of single phase CT and VT

6 Calculate ratio error automatically

7 Support YY/YD/DD/DY four connection mode in three phase transformer

8 Testing voltages is cut off automatically when one test is finished

9 Overload and reverse connection detect unit would prevent tester damaged in wrong connection mode.

10 Setting data and the test results are saved automatically. The history data can be recall again.

11 Print test results by micro printer
