Transformer Turns Ratio (TTR) Testing Equipment
I. Introduction:
-
This transformer turns ratio testing equipment 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 testing equipment 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
