The Special Transformer Ratio Tester is a high-performance automatic testing device specially designed for accurate ratio measurement and vector analysis of various transformer types. Developed for transformer manufacturers, power utilities, and maintenance service providers, it is widely used in factory quality inspection, commissioning acceptance, and preventive maintenance applications.
Unlike conventional ratio testers, this instrument supports comprehensive blind testing without requiring prior transformer connection information. It automatically identifies and measures key parameters including turns ratio, phase displacement, polarity, and vector group, providing reliable diagnostic results for complex transformer structures.

A:Yes.The SXTTR-V provides accurate phase angle measurement between the high-voltage and low-voltage sides.
• Phase angle range: 0°–360°
• Phase angle resolution: 0.01°
• Phase angle accuracy: 0.1°
This function allows testing of non-standard phase-shifting transformers.
A:The blind test function simplifies transformer testing procedures.
Without selecting transformer connection type or vector group manually, the SXTTR-V can automatically analyze the transformer connection condition and measure:
• Turns ratio
• Vector group
• Phase angle
This reduces operation errors and improves field testing efficiency.
A:Yes.The SXTTR-V supports tap position testing. It can quickly measure the turns ratio and ratio error at different tap positions.
Users only need to input the rated ratio once, and the instrument can automatically calculate ratio errors for different tap positions.
A:The transformer turns ratio measurement range is:0.9–10000
Measurement accuracy:
• 0.1% (ratio range 0.9–200)
• 0.2% (ratio range 200–2000)
• 0.3% (ratio range 2000–10000)
Customized equipment with full-range 0.1 accuracy is available according to customer requirements.
A:The SXTTR-V can complete a three-phase transformer test within:≤35 seconds
This helps improve efficiency during transformer commissioning and maintenance operations.
