HM-5001 high Accuracy Transformer Turn Ratio Meter / TTR tester
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
