Online Dga Monitoring System for Dissolved Gas Content in Transformer Oil
Product Description
HZGC-1210 On-line Oil Chromatography Monitoring System is capable of fully automated quantitative cycle cleaning, oil sampling, oil-gas separation, sample analysis, data processing, and real-time alarms. It continuously monitors the content and growth rate of dissolved fault gases in the oil of oil-immersed high-voltage equipment such as transformers. Combined with an integrated fault diagnosis expert system, it predicts potential equipment hazards, thereby preventing accidents, reducing significant losses, and enhancing operational reliability.
Developed through decades of expertise in power chromatography and degassing technology, and refined with insights from domestic and international online monitoring solutions, the HZGC-1210 delivers outstanding stability, reliability, and precision.
