GDBC-901 Three and Single Phase Turn Ratio Meter

1. Product introduction

GDBC-901 Three and Single Phase Turn 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
