- Ratio Tester for Current Transformer is designed according IEC76-1, IEC60044 and GB/T1094.
- 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.
II. 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
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
8 Testing voltages is cut off automatically when one test is
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
