Functional Characteristics:

• Real-time Monitoring: Continuously monitors dissolved gases in transformer oil (such as hydrogen, carbon monoxide, ethylene, and acetylene) and humidity levels.
• Fault Diagnosis: Provides alerts for potential faults by analyzing key parameters, helping to prevent equipment failures.
• Temperature Monitoring: Monitors both internal and external temperatures of the transformer to assess thermal stability and identify abnormal temperature rises.
• Humidity Monitoring: For oil-immersed transformers, humidity monitoring helps evaluate insulation performance and prevent moisture-related issues.
• Remote Monitoring and Communication: Supports network connectivity for remote monitoring, allowing operators to access critical equipment status information anytime, anywhere.
• Data Recording and Analysis: Records historical data on transformer operation, facilitating trend analysis and condition assessment.
• Alarm Function: Features multiple alarm levels (Alert and Alarm) to indicate increasing severity of detected issues. Alarms can be set based on sensor readings or calculated transformer models.
• Self-test and Self-diagnosis: The device performs regular self-tests to ensure reliable operation and early detection of potential issues.
• Expandability: Allows connection to additional sensors (such as load, oil temperature, and environmental temperature sensors) to enhance monitoring capabilities.

Application Scenarios:

• Power Generation and Distribution: Used in power plants and substations to monitor the condition of transformers, ensuring stable power supply and reducing unplanned outages.
• Industrial Automation: Suitable for various industrial settings where transformers are critical equipment, providing real-time monitoring and fault prevention.
• Renewable Energy: Applied in wind farms and solar power plants to monitor transformers in renewable energy systems, supporting efficient operation and maintenance.
• Smart Grids: Integrates with smart grid systems to provide real-time transformer status information, enhancing grid reliability and responsiveness.
• Large-scale Infrastructure: Used in infrastructure projects such as railways, airports, and data centers to monitor transformers and ensure continuous operation of critical facilities.
