Three-Phase Transformer High Power Test Systems
The SXBZ-III series Three-Phase Transformer Test Systems is
engineered for comprehensive factory acceptance and maintenance
testing of various transformers. This advanced system finds
extensive application across power supply and distribution
networks, transformer manufacturing facilities, maintenance
centers, and industrial enterprises.
System Features
1. Suitable for testing transformers, reactors, and high-voltage
switchgear across various voltage levels.
2. Fully PLC-controlled measurement integrates primary wiring
circuit display, measurement, trace monitoring, data analysis,
report storage/printing, and protection into a unified testing
system.
3. All test calculations are performed by an Industrial PC (IPC),
with results and measurement data displayed directly on-screen,
significantly improving accuracy and efficiency.
4. The test system can be customized into bench-type,
microcomputer-type, or other configurations as required, making it
adaptable to various testing environments.
