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 components 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, 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 happening 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 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 regular laboratory testing to continuous online monitoring marks a significant improvement in transformer upkeep.

Benefits of Online Dissolved Gas Analysis (DGA)

1. Real-Time Monitoring: One of the most considerable advantages of Online DGA is the capability to monitor transformer health in real time. This constant data stream enables the early detection of faults, enabling operators to take preventive actions before a minor concern intensifies into a major issue.

2. Increased Reliability: Online DGA systems boost the reliability of power systems by providing constant oversight of transformer conditions. This lowers the danger of unexpected failures and the associated downtime and repair work expenses.

3. Data-Driven Maintenance: With Online DGA, maintenance strategies can be more data-driven. Instead of relying exclusively on scheduled maintenance, operators can make informed choices based on the actual condition of the transformer, causing more efficient and cost-effective upkeep practices.

4. Extended Transformer Lifespan: By discovering and addressing concerns early, Online DGA contributes to extending the lifespan of transformers. Early intervention avoids damage from escalating, maintaining the integrity of the transformer and guaranteeing its continued operation.

5. Enhanced Safety: Transformers play an important role in power systems, and their failure can cause dangerous scenarios. Online DGA helps alleviate these dangers by providing early warnings of possible problems, permitting timely interventions that secure both the equipment and workers.

Key Features of Online Dissolved Gas Analyser Systems

Online Dissolved Gas Analyser systems are designed to supply continuous, precise, and reliable tracking of transformer health. Some of the key features of these systems consist of:.
