The PTDGA-1001T is a continuous, 24/7 online monitoring system designed to detect fault-characteristic dissolved gases and moisture in insulating oil for main transformers and shunt reactors. By replacing manual offline oil sampling with real-time condition monitoring, the device delivers early fault warnings, significantly reduces operational labor costs, and mitigates human safety risks.
Core Technology
Unlike conventional gas chromatography (GC) systems, the PTDGA-1001T utilizes a narrow-linewidth semiconductor laser combined with patented sub-ultrasonic resonant photoacoustic spectroscopy (PAS). This advanced design eliminates chromatographic columns and mechanical moving parts, ensuring superior stability and substantially lower maintenance costs.
Key Capabilities
- Comprehensive Real-Time Measurement: Continuously tracks concentrations of Hydrogen, Carbon Monoxide, Acetylene, Methane, Ethylene, Ethane, and trace moisture.
- Intelligent Diagnostics: Built-in algorithms automatically identify latent insulation defects, including low-temperature and high-temperature overheating, partial discharge, and arcing short-circuits.
- Seamless Integration: Supports local data storage and multi-channel remote data transmission to substation central control systems for round-the-clock monitoring.
