A Chronicle of Sansion Power's Overseas Expansion: Transformer Test System Shipped Overseas

2026-05-28

Recently, Sansion Power announced some exciting news—a Comprehensive Transformer Test System worth millions of yuan has completed its final debugging, been packaged, and officially shipped overseas. This is not just a routine product shipment, but also a powerful testament to the continued global reach of China's power testing technology.

The SXBZ series Transformer Test System can perform multiple functions in one stop, including turns ratio group, DC resistance, and short-circuit impedance. It requires only one wiring connection and can automatically generate reports, improving testing efficiency by over 60%. The product conforms to international standards, is compatible with transformers up to 1000KV, and features multiple protection and anti-interference technologies for stable and accurate operation. With its intelligent user interface, it is easy to use, and its modular structure significantly reduces future maintenance costs.

10ms Instant Power Cut-off

A Robust Three-Tier Safety Protection Network The high-voltage, high-current environment of power testing places stringent demands on system safety. The SXBZ series achieves a breakthrough improvement in safety design:

Three-Tier Overload Protection Mechanism: The system incorporates multiple hardware and software protections, enabling real-time millisecond-level monitoring of faults such as overcurrent, overvoltage, and abnormal short circuits.
10ms Instant Power Cut-off: Once a fault current is detected, the system can rapidly cut off the power supply within 10 milliseconds, maximizing the protection of test personnel and preventing secondary damage to the transformer under test.

Modular and Highly Integrated Architecture for a Complete Testing Loop

The SXBZ system adopts a modular and system integration design, integrating all core components required for transformer testing to form a complete testing loop:

Central Control Console: A modern human-machine interface that displays test curves and data in real time.
Transformer Integrated Instrument Cabinet: Contains a high-precision power analyzer, DC resistance tester, and turns ratio tester.
Integrated Sampling Cabinet (Current/Voltage): High-precision sensors accurately acquire signals from both high and low voltage sides.
Power Distribution and Voltage Regulation System: Equipped with a power distribution cabinet, induction voltage regulator, and medium-frequency generator set to meet the requirements of induction withstand voltage and frequency doubling tests.
Supporting Transformer Set: Includes test transformers and intermediate transformers, flexibly matching testing requirements for different voltage levels.

Wide Range of Applications

The SXBZ series transformer comprehensive testing system boasts strong applicability and scalability, and is widely used in:

Power transformer manufacturers (factory testing, type testing assistance)
Power supply and distribution systems and grid operation and maintenance departments (handover testing, regular routine inspections)
Professional transformer repair and testing centers (fault diagnosis, post-repair performance verification)
Large industrial and mining enterprises and energy units (daily maintenance of self-owned substation equipment)
