Transformer Ratio meter

Production Description:

GDBC-901 Transformer Ratio Tester I.Functions 1. The voltage ratio measurement for three or singe phase transformer 2. The group vector measurement for three phase transformer. 3. The polarity measurement for 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 operator 11. Over current protection unit integrated in software and hardware 12. Upload the test results to PC by RS232 and make word report by software II.Technique index 1. Ratio measurement range:1—10000 2. Group measurement:1—12 3. Phase measurement error:1 degree 4.
