1. Product introduction
Transformer ratio tester 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
