Automatic Transformer Ratio Meter, Brand Name : GOLD

We are offering automatic transformer ratio meter,
1. Product introduction:
gdbc-901 is designed according iec76-1, iec60044 and gbt1094. 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 yyyddddy 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
