Goldhome's High-Voltage Electric Oil-Gas Chromatography Improves Transformer Maintenance Standards
Wuhan Goldhome Hipot Electrical Co., Ltd. continues to provide high-end testing equipment for the electrical industry, with its gas-oil chromatograph specifically designed for transformer oil monitoring being a prime example. This device plays a crucial role in detecting the early signs of insulation deterioration and potential faults in power transformers.
The Importance of Oil Chromatography: Preventing Destructive Failures in Transformers
Transformers are the backbone of electrical systems, and internal faults (such as overheating, partial discharge, electrical stress) can lead to costly downtime and even explosions. These failures release specific gases (such as methane, ethane, ethylene, acetylene, hydrogen, and carbon monoxide) dissolved in the insulating oil. The 9890 Gas Chromatograph Analyser analyses these dissolved gases to determine the type and severity of the failure, enabling operators to take preventive measures before a failure occurs. It complies with industry standards such as GB/T 7252, IEC 60599, and ASTM D3612, ensuring compliance for power companies, power plants, and transformer manufacturers.
Key advantages: speed, accuracy, and automation.
The 9890 redefines oil chromatography testing with user-focused innovations and technical excellence:
Fast analysis: completes a full test of gaseous components (H₂, CH₄, C₂H₆, C₂H₄, C₂H₂, CO, CO₂) in just 15 minutes, 30% faster than traditional models, enabling higher throughput for laboratories and field teams.
Ultra-high sensitivity: Detects gas concentrations as low as 0.1 μL/L (ppm) with a measurement error of ≤±3%, ensuring accurate identification of even minor defects.
Fully automated operation: From sample injection to data analysis, this tester eliminates manual intervention. Users simply load the oil sample; the system automatically performs gas extraction, separation, and detection, as well as result calculation, reducing human error and training requirements.
Intelligent data management: A 7-inch color touchscreen displays chromatograms and test reports in real time. The device stores up to 5,000 historical records and supports data export via USB/network, integrating seamlessly with laboratory information management systems (LIMS).
Designed to ensure industrial reliability and flexibility
Goldhome Hipot designed the 9890 model to operate in harsh industrial environments and various applications:
Stable performance: equipped with a high-precision thermal conductivity detector (TCD) and flame ionisation detector (FID) with anti-interference technology, ensuring consistent results even in environments with high humidity or electromagnetic interference (EMI).
Wide range of applications: suitable for transformer oil, turbine oil, and insulating oil in electrical networks, petrochemical plants, railway systems, and renewable energy power plants.
Low maintenance: modular design and automatic diagnostic functions of the tester facilitate maintenance, with replaceable components and automatic calibration reminders that extend its service life.
