Transformer Ratio Tester TTR Features:
Transformer Ratio Tester TTR is designed to measure the transformer voltage conversion ratio of three-phase and single-phase power transformers.
- Measurement range; max. 10000.
- Triple or single phase TTR test.
- High test speed, test result in 10 s.
- Suitable for different transformers, Z type winding transformers can test.
- Excellent protection functions, high / low voltage reverse connection protection and short circuit protection.
- Automatic measurement of TTR data, error value at different steps.
- Micro printer, large colour LCD display.
- Maximum 99 step transformer measurement.
- With the storage function, the test results can be stored in memory.
- RS232 or RS485 interface, Neutral point test (optional)
