Automatic Power Transformer Test System with Integrated Measurement and Data Analysis Functions

The SXBZ Series Transformer Comprehensive Test System is designed to support electrical testing activities in transformer maintenance workshops, repair facilities, and power equipment service centers. By integrating selected test instruments, control units, and auxiliary equipment into one coordinated system, it provides a practical solution for transformer electrical testing and post-maintenance verification.

For service teams handling transformers of different specifications, the system can be configured according to actual testing requirements, helping simplify equipment coordination and create a more organized testing workflow.

• Integrated Testing ArrangementMultiple testing instruments and auxiliary units can be integrated into a centralized system. This helps service teams manage their testing equipment more efficiently and reduces the need to coordinate separate devices manually.
• Support for Post-Repair VerificationAfter winding repair, component replacement, or other maintenance work, the appropriate electrical tests can be selected to verify the transformer’s condition before it returns to service. Available tests depend on the final system configuration.
• Computer-Based Measurement and ControlThe computer-based control arrangement supports centralized operation and measurement management, helping operators follow a more consistent testing procedure.
• Configurable for Different Service RequirementsThe system configuration can be adapted to the transformer types, rated parameters, and testing procedures handled by the service facility. Selected instruments and auxiliary equipment are determined according to the project requirements.
• Overcurrent ProtectionThe system incorporates a three-level overcurrent protection design. Under specified operating conditions, the protection arrangement is designed to interrupt fault current within 10 ms. Actual protection performance is subject to the applicable technical specification and operating conditions.

• Winding DC Resistance Measurement: Measures winding resistance to support winding condition checks and post-repair verification.
• Turns Ratio Measurement: Checks the transformation ratio to help verify winding ratio requirements.
• Electrical Parameter Analysis: Uses a compatible power analyzer or other selected instruments to measure specified electrical parameters.
• High-Voltage Testing: Can be incorporated when the required high-voltage test equipment and corresponding safety arrangements are included in the system configuration.
• Additional Transformer Tests: Other functions may be considered according to the transformer type, service procedure, and customer specification.
