Understanding 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 crucial elements in electrical networks, and their effective operation is important for the dependability and safety of the whole power system. Among the most dependable and extensively 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, providing real-time insights into transformer conditions. This article delves into the significance of Online Dissolved Gas Analysis (DGA) and its effect 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 reaction time. The procedure of sampling, 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 restrictions, Online Dissolved Gas Analysis (DGA) systems have been developed. These systems are installed directly 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 advancement in transformer upkeep.
