Transformer Oil on-Line Monitoring System

Model NO.: VGTCA-3600 Protection: Corrosion Resistance Housing: Steel HS Code: 84 Certification: ISO9001 Installation: Vertical Origin: Ningbo China Exact understanding of the running status of the transformer is the key to maintain the safe operation of the
power system.
If local overheating or partial discharge is present in the transformer, the insulating oil or solid insulator in the
trouble location will release small molecules hydrocarbon gases such as CH4, C2H6, C2H4, C2H2 and other
gases such as H2, CO, CO2. Both of the concentration of every gas in insulating oil and the total concentration
of inflammable gas in oil (TCG) can be used as indicators to diagnose the internal faults of the transformer.
Transformer Oil On-line Monitoring System is a new transformer oil chromatogram on-line monitoring
product. Our company researches and develops the product by taking International Electrotechnical
Commission (IEC) Standard and National Standard of Transformer Oil Monitoring of China Electric Power
Industry (GB) as test research and development basis strictly, introducing advanced detection technology and
high-precision detection components from abroad and absorbing the field operating experience of on-line
chromatogram monitoring system for gas in transformer oil at home and abroad.
Transformer Oil On-line Monitoring System adopts oil gas degassing technology that combines vacuum and
ultrasound, uses the international newest high efficiency compound chromatographic column and
high-precision sensor to accurately analyze seven gases with fault features including hydrogen (H2), carbon
monoxide (CO), methane (CH4), ethane C2H6), ethylene (C2H4), acetylene (C2H2) and carbon dioxide (CO2)
and to assist in realizing on-line analysis of micro-water in oil.
Transformer fault information can be captured promptly by using Transformer Oil On-line Monitoring System
to scientifically guide the operation and maintenance of the equipment.
