Dissolved gas analysis (DGA) and moisture analyzer
The combination of moisture in oil and inthe cellulose is an indicator of aging. The most important method for thediagnosis of aging processes as a result of dielectric, thermal, dynamic andchemical aging in the oil and oil-paper insulation is the Dissolved GasAnalysis (DGA). Chongqing Kailian Yongrun ...

Dissolved gas analysis (DGA)
During the natural aging processes of oiland insulating parts, especially in the case of thermal or electrical failures,cracked gases form and are dissolved in the oil. The rate of decomposition andthe type of gases change during defective operation, which could be results ofthe thermal overloading and ...
