Comprehending 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 downplayed. Transformers are crucial elements in electrical networks, and their effective operation is essential for the reliability and safety of the whole power system. Among the most reputable and extensively used methods to monitor the health of transformers is through Dissolved Gas Analysis. With the development of innovation, this analysis can now be performed online, providing real-time insights into transformer conditions. This article explores the significance of Online Dissolved Gas Analysis (DGA) and its effect on transformer upkeep.

The Basics of Dissolved Gas Analysis (DGA)

Dissolved Gas Analysis (DGA) is a diagnostic tool utilized to spot 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 throughout faults or regular aging procedures. By analysing the types and concentrations of these gases, it is possible to identify and identify different transformer faults before they result in disastrous failures.

The most frequently kept an eye on 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 provides specific information about the type of fault that may be happening within the transformer. For instance, high levels of hydrogen and methane might suggest partial discharge, while the presence of acetylene frequently suggests arcing.

Development of DGA: From Laboratory Testing to Online DGA

Typically, DGA was performed by taking oil samples from transformers and sending them to a laboratory for analysis. While this technique is still common, it has its restrictions, particularly in terms of response time. The process of sampling, shipping, and evaluating the oil can take numerous days or perhaps weeks, throughout which a vital fault may escalate unnoticed.

To overcome these limitations, Online Dissolved Gas Analysis (DGA) systems have been established. These systems are set up 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.
