High accury 3-phase Power Transformer Turn Ratio Tester TTR testing Meter with Turn Ratio 1~10000
- It is designed according IEC76-1 and IEC60044.
- It could be applied to test the turns ratio and group vector of single or three phase transformer.
- Also the connection group of itself could be calculated with the ratio.
- All parameters are measured in one test for three phase transformer.
- The voltage ratio measurement 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 tester
- Print the test results by micro 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
