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 vital parts 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 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 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 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
Traditionally, 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 and even weeks, during which a crucial fault might escalate 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 advancement in transformer maintenance.
Benefits of Online Dissolved Gas Analysis (DGA)
1. Real-Time Monitoring: One of the most substantial benefits of Online DGA is the ability to monitor transformer health in real time.
