The SXBB Automatic Transformer Turns Ratio Tester is a high-performance transformer diagnostic instrument developed for accurate and efficient transformer ratio measurement.
Transformer turns ratio testing is an essential inspection method used during transformer manufacturing, installation, commissioning and preventive maintenance.
By measuring the relationship between primary and secondary winding voltage, engineers can verify whether the transformer meets design requirements and identify possible problems caused by incorrect winding connections, manufacturing defects or transportation damage.
Sansion Power SXBB series integrates automatic measurement technology, intelligent calculation functions and digital data management to provide a complete testing solution for power transformers, distribution transformers, PTs and CTs.
The transformer ratio tester is designed with a three-phase sine-wave inverter output system, providing stable test signals and improving measurement accuracy.
A transformer is one of the most important components in power transmission and distribution systems.
The transformer turns ratio directly determines voltage conversion performance.
The basic formula is:
Turns Ratio = N1/N2 = U1/U2
Where:
During transformer operation, abnormal turns ratio values may indicate:
Using an automatic transformer ratio tester helps engineers quickly verify transformer conditions and improve power system reliability.
The SXBB TTR Tester accurately measures the ratio between transformer high-voltage and low-voltage windings.
Applications include:
The tester automatically determines transformer connection group.
This function helps verify phase relationship and winding configuration, reducing manual calculation requirements.
The equipment supports voltage transformer ratio measurement.
It helps users verify PT performance for:
