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 understated. Transformers are important components in electrical networks, and their effective 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 performed 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 normal ageing processes. By evaluating the types and concentrations of these gases, it is possible to recognize and detect numerous transformer faults before they lead to catastrophic failures.
The most commonly kept track of 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 offers 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 restrictions, especially in regards to reaction time. The process of sampling, shipping, and analysing the oil can take several days or even weeks, during which a critical fault may intensify undetected.
To conquer these restrictions, Online Dissolved Gas Analysis (DGA) systems have been developed. These systems are installed straight on the transformer and continually monitor the levels of dissolved gases in real time. This shift from routine lab testing to continuous online monitoring marks a significant improvement in transformer upkeep.
