GDBC-901 Digital Transformer Turn Ratio Meter

Transformer ratio meter is applied to measure the voltage ratio of three or single phase transformer. All the data and test results are shown on a 320*240 LCD screen. All the test results could be printed by the micro printer or saved in the storage of the tester. The tester has a good performance on auto protection and anti-disturb.

2. Main functions and Characters

♦ Automatically measure transformer connection group

♦ Automatically switch range

♦ Automatically measure ratio of single or three phase transformer

♦ Automatically measure ratio of single or three phase voltage transformer

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

♦ Calculate ratio error automatically

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

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

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

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

♦Print test results by micro printer
