Single Phase or Three Phase Transformer Voltage Ratio/Connection Group Test Automatic Turns Ratio Tester


Function and Applications

1. Measuring transformer voltage ratio (three-phase, single-phase).
2. Automatic measurement of transformer group (three-phase, single-phase).
3. Detect the position of the transformer tap switch according to the measurement result of the transformation ratio and the standard transformation ratio setting.
4. Measuring the transformation ratio of current transformer.
5. Display the excitation current during the transformation ratio measurement.
6. Automatic calculation of transformer ratio error.
7. With micro printer, print test results.
8. Automatically identify reverse connection and short circuit, protect the tester and the operator, and promptly give error prompts.
9. With RS232 serial communication, upload test data to the computer.


Advantages

a) 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.
b) Automatic voltage regulation, with automatic protection functions such as transformer reverse connection, overcurrent, etc., to avoid damage to the instrument due to incorrect operation.
c) It can be used to detect the transformation ratio of power transformers, voltage transformers and current transformers at the same time.
d) Convenient standard transformation ratio setting template, no need for test personnel to manually calculate the standard transformation ratio value.
