Transformer Oil on-Line Monitoring System

Product introduction:

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.
