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 important elements in electrical networks, and their effective operation is necessary for the reliability and safety of the entire power system. Among the most dependable and commonly utilized methods to monitor the health of transformers is through Dissolved Gas Analysis. With the introduction of innovation, 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 upkeep.

The Basics of Dissolved Gas Analysis (DGA)

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

The most typically kept track of 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 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 typically recommends arcing.

Advancement of DGA: From Laboratory Testing to Online DGA

Generally, DGA was carried out by taking oil samples from transformers and sending them to a lab for analysis. While this approach is still widespread, it has its constraints, especially in regards to action time. The procedure of tasting, shipping, and analysing the oil can take a number of days or even weeks, during which a critical fault might intensify undetected.

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

Advantages of Online Dissolved Gas Analysis (DGA)
