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 techniques to monitor the health of transformers is through Dissolved Gas Analysis. With the arrival 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 influence on transformer maintenance.
The Basics of Dissolved Gas Analysis (DGA)
Dissolved Gas Analysis (DGA) is a diagnostic tool used to discover 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 detect numerous transformer faults before they lead to catastrophic 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 instance, 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 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 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.
