Product Presentation
By continuously detecting and diagnosing incipient internal faults through gas content analysis, it provides real-time insights into equipment health. This effectively overcomes the limitations of long turnaround times associated with traditional laboratory chromatography.
Utilizing advanced gas chromatography technology, the SE3000 rapidly and accurately measures the concentrations of all critical dissolved gases—including H₂, CO, CO₂, CH₄, C₂H₂, C₂H₄, and C₂H₆- directly on-site. An integrated expert system intelligently diagnoses potential latent faults based on this data. It is suitable for monitoring oil-filled high-voltage equipment such as transformers and reactors rated at 35kV and above. Optional functions include monitoring moisture content in oil, core/clamp ground current, ambient temperature, and additional gases like O₂ and N₂.
Product Feature
-
Flexible Communication
The system supports multiple built-in communication interfaces, including optical fiber, Ethernet, and RS485. It is compatible with IEC61850, I2, and serial port 103 protocols, enabling seamless integration with substation automation or dispatch systems from major manufacturers.
-
Functional Expandability
The main control unit chassis adopts a plug-in architecture, allowing each functional board to operate independently while communicating via a backplane. This not only simplifies board maintenance but also enables expansion of monitoring capabilities through the addition of various functional boards, resulting in comprehensive and versatile monitoring.
-
Modular Design
The system features a fully modular design across all components, facilitating simple maintenance, high operational efficiency, and convenient upgrades or replacements. -
Strong Adaptability
The system cabinet meets IP55 protection standards and is equipped with an internal climate control system, ensuring reliable operation under harsh conditions such as high temperature, high humidity, low temperature, and dusty environments.
