TransGuard Monitoring System
Transformers are critical to electrical power systems. Their eliability and availability are key to profitable power generation and transmission¸ while continuous supervision is essential to evaluate transformer performance and safe operating conditions.
TheTransGuard is a high-performance transformer intelligent control system integrating protection, measurement, control, communication and analysis. It adopts advanced measurement and control technology and protection principle, the hardware and software adopts modular structure and anti-interference design, the operation is simple and reliable.
The system collects the important parameters of the transformer through the configured sensors and upload them to the TransGuard device. Through the analysis of its expert system, the real-time operation status of the transformer is obtained, and the information is processed by local control device. Conclusion and data are sent to the TransGuard background monitoring system workstation through IEC61850, which is convenient for the user to monitor and observe the operation status of the transformer and make corresponding maintenance plan.
The TransGuard intelligent online monitoring module is equipped on the transformer side, and its functions can be flexibly configured according to the field requirements, so as to access different sensing devices and obtain demand parameters for analysis.
