Understanding the Importance of Online Dissolved Gas Analysis in Transformer Maintenance

In the world of power systems and transformer upkeep, the role of Dissolved Gas Analysis (DGA) can not be understated. Transformers are important components in electrical networks, and their effective operation is necessary for the reliability and safety of the entire power system. Among the most reliable and commonly utilized approaches to monitor the health of transformers is through Dissolved Gas Analysis. With the arrival of technology, this analysis can now be performed online, offering real-time insights into transformer conditions. This article looks into the significance of Online Dissolved Gas Analysis (DGA) and its influence on transformer upkeep.

The Basics of Dissolved Gas Analysis (DGA)

Dissolved Gas Analysis (DGA) is a diagnostic tool utilized to detect and measure gases dissolved in the oil of transformers. These gases are produced due to the decomposition of the insulating oil and other materials within the transformer during faults or typical aging procedures. By evaluating the types and concentrations of these gases, it is possible to identify and diagnose various transformer faults before they result in disastrous failures.

The most commonly kept track of gases include hydrogen (H ₂), methane (CH ₄), ethane (C ₂ H ₆), ethylene (C ₂ H ₄), acetylene (C ₂ H ₂), carbon monoxide (CO), and carbon dioxide (CO ₂). Each of these gases offers particular information about the kind of fault that might be taking place within the transformer. For example, high levels of hydrogen and methane may show partial discharge, while the existence of acetylene often recommends arcing.

Evolution of DGA: From Laboratory Testing to Online DGA

Traditionally, DGA was performed by taking oil samples from transformers and sending them to a laboratory for analysis. While this method is still prevalent, it has its limitations, particularly in regards to action time. The process of sampling, shipping, and analysing the oil can take several days or even weeks, during which a critical fault may intensify undetected.

To conquer these restrictions, Online Dissolved Gas Analysis (DGA) systems have been developed. These systems are installed straight on the transformer and constantly monitor the levels of dissolved gases in real time. This shift from periodic laboratory testing to constant online tracking marks a substantial development in transformer maintenance.
