Mr. Ricky CasipeWith regards of our test instrument the’re all in Good condition. I'll purchase some instrument sooner. Thank you very much -
Ms. Remy GalaponFrom year 2020 to 2023, we purchased more than 30 equipment from Delta Technology, they are all work well and the service from Delta Technology is also good. -
Mr. MilanThe VLF-80 Tester is perfect and thank you.

Product Description
TTR-III With Battery Portable Transformer Turn Ratio Polarity Testing Instrument
Introduction:
TTR-III Portable Transformer Turn Ratio Polarity Testing Instrument is independently developed and produced by our company according to the user's on-site use requirements. It is easy to operate, complete in function, and stable and reliable in data.
At the same time, it is also the first variable ratio tester in China that can perform blind test (accurate measurement without knowing the connection method and group of the transformer under test) and test the parallel running state of the main transformer.
TTR-III Portable Transformer Turn Ratio Polarity Testing Instrument can test problem of parallel operation of transformers from the root.
TTR-III Portable Transformer Turn Ratio Polarity Testing Instrument is the most advanced and multi-functional turns ratio tester in China.
Main Parameters:
1. Ratio measurement range: 0.9~10000.
2. Measurement speed: complete the three-phase test within 1 minute.
3. Accuracy: High voltage side voltage is 0.05%, low-voltage side voltage is 0.1%
4.Ratio measurement accuracy: 0.9-1000: 0.1% 1000-3000: 0.2% 3000-10000:0.3%
5. Power supply: AC220V, 50Hz, and DC rechargeable battery.
5. Weight: 3Kg
Main Features:
1. Multi-functions:
| Parameters Testing | Single Phase Transformer | 3 Phase Transformer |
| Turns Ratio Testing | Yes | Yes |
| Phase Angle Testing | Yes | Yes |
| Polarity Testing | Yes | Yes |
| Vector Group Testing | / | Yes |
2. Blind test function: There is no need to select the wiring method and group, and the measurement of Y/△, △/Y transformers does not require external short-circuit, and the wiring method can be automatically switched according to the selected test content.
3. Tap test: It can quickly measure the transformation ratio and transformation ratio error at each tap changer position. The rated transformation ratio only needs to be input once, and the transformation ratio error of each tap position can be calculated without repeated input.
4. The magnitude and phase relationship between various voltages and currents are visually represented by vector diagrams, so that users can easily understand the actual meaning of each parameter.
5. The test source used by this instrument is a digitally synthesized standard sinusoidal digital source with a distortion degree of less than 0.1% and is not affected by the quality of the working power supply
