Systematic Understanding of Power Preventive Test Equipment such as Transformer Testers
Combined with your previous systematic understanding of power preventive test equipment such as switch characteristic testers and transformer testers, the online oil chromatography monitoring device (Dissolved Gas Analysis, DGA) is precisely the exclusive "blood analyzer" and "24-hour贴身 health monitor" for large oil-filled equipment like transformers and reactors.
If the previous equipment was conducting regular "physical examinations" on power equipment, then online oil chromatography monitoring is real-time monitoring of the equipment's internal "vital signs." Its core task is to capture trace fault gases dissolved in transformer oil, detecting latent hazards such as internal overheating and discharge in advance.
The following is a detailed analysis of the core principles, technical characteristics, and application status of this system:
