Product Description

GDBC-901 Three Phase Transformer Turns Ratio Tester TTR Meter

1) GDBC-901 Three Phase Transformer Turns Ratio TTR Tester is designed according IEC76-1 and IEC60044.
2) GDBC-901 Three Phase Transformer Turns Ratio TTR Tester could be applied to test the turns ratio and group vector of single or three phase transformer.
3) Also the connection group of transformer could be calculated with the ratio.
4) All parameters are measured in one test for three phase transformer.

 

Main Functions:

• 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

Benefits:

• The test power supply is generated by the internal power amplifier of the tester, and the waveform distortion rate is less than 0.5% and is not affected by the quality of power supply.

• Automatic voltage regulation, with automatic protection functions such as transformer reverse connection, over-current, etc., to avoid damage to the instrument due to incorrect operation.

• It can be used for power transformer, CT and PT ratio detection.

• Convenient standard transformation ratio setting template, don't need to manually calculate the standard transformation ratio value.

• GDBC-901 is very light, only 20KG. It's easy to carry. It's suitable for field test.
