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 vital for the dependability and safety of the entire power system. One of the most trusted and widely used approaches to monitor the health of transformers is through Dissolved Gas Analysis. With the advent 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 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 decay of the insulating oil and other materials within the transformer throughout faults or normal ageing processes. By analysing the types and concentrations of these gases, it is possible to determine and identify numerous transformer faults before they cause disastrous failures.

The most commonly monitored 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 may suggest partial discharge, while the existence of acetylene frequently recommends arcing.

Development of DGA: From Laboratory Testing to Online DGA

Typically, DGA was carried out by taking oil samples from transformers and sending them to a lab 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 established. 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.
