Universal TTR Tester for Single and Three-Phase Transformer Ratio Testing
Factory wholesale price universal TTR tester designed for comprehensive transformer turns ratio testing of single and three-phase power, distribution, and instrument transformers.
Product Overview
Transformer turns ratio testing is essential for verifying that transformers maintain the correct ratio between primary and secondary windings according to rated voltage specifications. The SXTTR is a single-phase automated test set specifically engineered for turns ratio, phase shift, and excitation current measurements.
Key Features
- Automatic transformer connection group measurement
- Automatic group conversion and phase sequence switching
- Automatic measuring range selection and calibration
- Automatic calculation of relative error after inputting standard turns ratio
- Automatic voltage cutoff after test completion
- Automatic data saving with historical data browsing capability
- Simplified testing requiring only one turns ratio input for load transformers
