Product Description

Automatic Transformer Voltage Ratio and Current Ratio Tester TTR Meter
 

Application

 

• The voltage ratio test for three or singe phase transformer 

• The group vector test for three phase transformer.

• The polarity test for single phase transformer or CT/PT

• Voltage ratio error calculation

• Current transformer (CT) ratio test

• 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

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.
