Understanding the Importance of Online Dissolved Gas Analysis in Transformer Maintenance

In the world of power systems and transformer maintenance, the function of Dissolved Gas Analysis (DGA) can not be understated. Transformers are vital components in electrical networks, and their efficient operation is vital for the reliability and safety of the entire power system. One of the most reliable and widely utilized approaches to monitor the health of transformers is through Dissolved Gas Analysis. With the advent of technology, this analysis can now be carried out online, supplying real-time insights into transformer conditions. This article delves into the significance of Online Dissolved Gas Analysis (DGA) and its impact on transformer maintenance.

The Basics of Dissolved Gas Analysis (DGA)

Dissolved Gas Analysis (DGA) is a diagnostic tool utilized to identify and determine 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 recognize and diagnose various transformer faults before they result in devastating failures.

The most frequently kept an eye on gases consist of 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 occurring 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 analysing the oil can take numerous days or perhaps weeks, throughout which an important fault may intensify unnoticed.

To conquer these limitations, Online Dissolved Gas Analysis (DGA) systems have been developed. These systems are set up straight on the transformer and constantly monitor the levels of dissolved gases in real time. This shift from regular laboratory testing to continuous online tracking marks a substantial improvement in transformer upkeep.
