Understanding 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 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, 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 detect 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 throughout faults or typical ageing procedures. By evaluating the types and concentrations of these gases, it is possible to identify 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.
Development of DGA: From Laboratory Testing to Online DGA
Typically, 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 terms of response time. The process of tasting, shipping, and evaluating the oil can take numerous days or perhaps weeks, throughout which a vital fault may escalate unnoticed.
To overcome these limitations, 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.
