Reliable Automatic Turn Three Phase Transformer Turns Ratio Meter Ttr
Overview
TRANSFORMER TURN RATIO TESTER 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.
Main function and character
- The voltage ratio measurement of three or singe phase transformer
- The group vector measurement of three phase transformer.
- The polarity measurement of single phase transformer or CT/PT (CT that knee-point voltage should be more than 80V)
- Voltage ratio error calculation
- Voltage ratio range calculation of three phase transformer
- 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 tester
- Print the test results by micro printer
- Reverse connection detect unit to prevent the high voltage injected to the operate
- Over current protection in test voltage
- Upload the test results to make word report by RS232 interface
