Comprehending 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 important components in electrical networks, and their efficient operation is necessary for the reliability and safety of the entire power system. Among 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 looks 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 used to find 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 typically 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 supplies particular information about the type of fault that may be occurring within the transformer. For instance, high levels of hydrogen and methane might indicate partial discharge, while the presence of acetylene often suggests 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 procedure of tasting, shipping, and evaluating the oil can take a number of days and even weeks, during which a crucial fault might escalate undetected.

To get rid of these constraints, Online Dissolved Gas Analysis (DGA) systems have actually been established. These systems are installed directly on the transformer and continuously monitor the levels of dissolved gases in real time. This shift from periodic lab testing to constant online tracking marks a considerable development in transformer maintenance.

Advantages of Online Dissolved Gas Analysis (DGA)
