Product Description

GDDJ-DGA Transformer Oil Gas Chromatography On-line Monitoring System 

 

General Information

GDDJ-DGA Transformer Oil Gas Analyzer is an online monitoring device for dissolved gas in transformer oil based on gas chromatography technology. Potential fault are determined, release alert as per preset value through expert diagnosis system.

The device adopts distributed control sampling technology and has self-diagnosis and self-recovery functions. Each function module is weak coupling, function independent, adopting rack structure, easy for engineering maintenance.
