On-line Dissolved Gas Analyzer DGA

Additional Details

The MGA2000-6 is a new generation of Online Dissolved Gas Analyzer (DGA) equipment giving essential insight into the condition of transformers. Extensive field use proves that MGA2000-6 provides reliable information and represents invaluable tool for Asset Management. Accurate knowledge of the condition of the transformers is essential for all electrical networks and On-line Monitoring of critical transformers is increasingly vital. Dissolved Gas Analysis (DGA) and moisture measurement of the insulation oil are recognized as the most important tests for conditions assessment of transformers.

The “MGA2000-6 Transformer Online Multi-gas Analyzer” is a highly reliable, online monitoring instrument and system. It can analyze the concentrations and accumulation rates of dissolved gases inside transformer oil continuously, enable real-time and online monitoring. Automatic diagnosis of transformer faults can be performed by the fault diagnosis expert system of MGA2000-6. Such application is significant to prevent downtime incidents. Our technology and its application provide technical assurances for the transition from traditional Periodical maintenance to advanced Condition-based maintenance.

Innovative & advanced features
 
    Detection Principle: Using tailor-made nanocrystalline semiconductor detector to measure hydrogen (H2), carbon monoxide (CO), methane(CH4), ethylene(C2H4), acetylene(C2H2), ethane(C2H6), total combustible gases (TCG); Using moisture detection unit to detect water content in oil
