Dissolved gas oil analysis

Dissolved gas analysis (DGA) is the study of dissolved gases in transformer oil. It is also referred to as a DGA test. It is also referred to as a DGA test. Whenever a transformer undergoes abnormal thermal and electrical stresses, certain gases are produced due to the decomposition of the transformer oil. Dissolved Gas Analysis of Transformer Oil In today’s modern electric power industry, transformer oil sampling and analysis has begun to enjoy wide popularity. A good oil analysis program provides equipment owners the ability to determine the current condition of a transformer and schedule prevetive maintenance so as to avoid possible failures in future. C.

GAS IN OIL ANALYSIS Dissolved Gas Analysis. The most sensitive and reliable technique for evaluating the health Fault Identification. Large amounts of hydrogen and acetylene are produced, Interpretation and Historical Data. Powertech has one of the most comprehensive insulating oil data

The analysis of gases from petroleum products has been performed for decades using gas chromatography. However, this technique was not applied 

Dissolved gas analysis (DGA) is the study of dissolved gases in transformer oil. Insulating materials within transformers and electrical equipment break down to liberate gases within the unit. The distribution of these gases can be related to the type of electrical fault, and the rate of gas generation can indicate the severity of the fault.
