1.Application

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

2. Advantage

1) Voltage ratio measurement of three or singe phase transformer

2) Group vector measurement of three phase transformer.

3) Polarity measurement of single phase transformer or CT/PT

4) Voltage ratio error calculation

5) Current transformer ratio measurement

6) Excitation current measurement in ratio testing

7) Reproduction the AC test voltage from power source to reduce the effects of bad power source

8) Save the test results in the memory internal the tester

9) Print the test results by micro printer

10) Reverse connection detect unit to prevent the high voltage injected to the operate

11) Over current protection in test voltage

12) Upload the test results to make word report by RS232 interface
