Single Three Phase Transformer Turns Ratio Tester TTR Meter

I. Introduction:

• This transformer turns ratio tester can test voltage ratio for three or singe phase transformer

• The group vector measurement for three phase transformer.

• The polarity measurement for single phase transformer or CT/PT

• Voltage ratio error calculation

• Current transformer ratio measurement

• Excitation current measurement in ratio testing

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

• Save the test results in the memory internal the TTR meter

• This turns ratio meter can print the test results by micro build-in printer

• Reverse connection detect unit to prevent the high voltage injected to operator

• Over current protection unit integrated in software and hardware

• Upload the test results to PC by RS232 and make word report by software
