Revolutionizing Transformer Maintenance: Online Dissolved Gas Analyser of Transformer Oil
Transformers are the unsung heroes of our power infrastructure, silently stepping down voltage levels to ensure our homes and industries have access to electrical energy. However, these workhorses are not immune to wear and tear, and their health is critical to the stability of the grid. This is where online dissolved gas analyser of transformer oil comes into play, offering a sophisticated solution to monitor and maintain transformers efficiently and proactively.
The Power of Online Dissolved Gas Analyser
Online dissolved gas analyser (DGA) of transformer oil is an innovative and robust method for continuously assessing the condition of transformers. It involves the real-time analysis of gases that are dissolved in the transformer oil, enabling early detection of potential issues and allowing for preventive measures to be taken. This technology is a game-changer, and at the heart of this transformative process lies the Touch Screen GC System Model Dhruva S2TS, an NTPC and ERDA approved solution.
Customization to International Standards
One of the key advantages of the Dhruva S2TS is its versatility and adaptability. This cutting-edge equipment can be tailored to meet specific requirements and standards, such as ASTM D 3612 Section A or C and IEC 60567, 2005 Section 7.3 or 7.5. This adaptability ensures that the technology aligns perfectly with the needs of the user, making it a powerful tool for assessing and maintaining transformers of varying specifications.
Detecting Incipient Faults
The primary objective of online dissolved gas analyser is to identify incipient faults in transformers. By continuously monitoring the gases present in the oil, the technology can detect early signs of deterioration and damage to the transformer insulation. It’s akin to having a health monitoring system for your transformer, allowing you to diagnose issues at their infancy and take preventive action before they escalate.
Gas Chromatography: The Science Behind the Analysis
At the core of online DGA is gas chromatograph, a sophisticated analytical technique that separates and identifies the gases dissolved in transformer oil. This method is the key to identifying incipient faults, providing a comprehensive view of the transformer’s condition. The significant gases generated by the decomposition of oil and paper insulation include hydrogen, methane, ethane, ethylene, acetylene, carbon monoxide (CO), carbon dioxide (CO2), oxygen, and nitrogen. The concentrations of these gases can vary significantly based on the type and severity of fault conditions. Common fault conditions include arcing, partial discharge, overheating, and low-high temperature hot spots.
The Process: Separation, Identification, and Quantitative Determination
Online DGA involves a meticulous process of gas analysis. The technology extracts a sample of the transformer oil, separates the gases within the sample, identifies them, and quantifies their concentrations. The Dhruva S2TS performs all these tasks with impressive precision. With just a single injection of the oil sample, it provides a comprehensive analysis of the fault gases, with the specific gases analyzed depending on the user’s requirements.
The Advantages of Online Dissolved Gas Analyser
Now that we understand the technology and its components, it’s time to delve into the substantial advantages it offers. Online DGA is a proactive approach to transformer maintenance, and here are some of the key benefits it brings to the table.
Early Detection of Faults
The most significant advantage of online DGA is its ability to detect faults in their early stages. By continuously monitoring the gases within the transformer oil, it can identify the presence of fault gases as soon as they emerge. This early detection provides a significant window of opportunity for intervention and preventive maintenance.
Preventing Catastrophic Failures
Catastrophic failures of transformers can be costly and disruptive. They can result in extended downtime, expensive repairs, and even damage to surrounding equipment. Online DGA acts as an early warning system, helping to prevent such catastrophic failures by detecting issues well before they reach a critical stage.
Data-Driven Decision-Making
Online DGA offers a data-driven approach to maintenance. The continuous monitoring and data collection provide valuable insights into the transformer’s condition. Asset owners and maintenance teams can make informed decisions based on real-time data, ensuring that resources are allocated effectively and maintenance efforts are focused on transformers that need attention.
Reduction in Maintenance Costs
By addressing issues in their early stages, online DGA helps reduce overall maintenance costs. Preventive maintenance is typically less expensive and disruptive than corrective maintenance after a catastrophic failure. This technology also helps extend the lifespan of transformers, reducing the need for premature replacements.
Improved Reliability
A reliable power supply is essential for homes, industries, and businesses. Online DGA enhances transformer reliability by minimizing unplanned outages and ensuring that transformers operate within safe and efficient parameters.
Real-Time Insights
The Dhruva S2TS, in particular, offers the advantage of real-time insights. It provides near-instantaneous data on fast-developing faults, allowing for rapid responses to emerging issues. This rapid mode ensures that asset owners and maintenance teams are always one step ahead when it comes to transformer health.
Compatibility with Various Insulating Oils
Transformers use various types of insulating oils, from traditional mineral oils to newer ester-based fluids, both natural and synthetic. Online DGA is compatible with these different oil types, ensuring its applicability across diverse transformer configurations.
Enhanced Monitoring Solution
The combination of enhanced computing power, highly scalable I/Os, and integrated human-machine interface (HMI) in the Dhruva S2TS creates a powerful and flexible transformer monitoring solution. This combination streamlines data collection, analysis, and reporting, making it a comprehensive and user-friendly platform.

Online dissolved gas analyser has a profound impact on the management of transformer assets. Its applications extend to various scenarios and industries, and its implementation has the potential to enhance overall grid reliability.
Monitoring Transformer Bushings
One critical application is the continuous monitoring of transformer bushings. Bushings are under constant high stress due to line voltage and the heat generated by current flow. They are susceptible to various stressors, including manufacturing defects, aging, thermal cycling, pollution, and external flashovers. These stressors can lead to bushing insulation deterioration. If left undetected, this deterioration can result in catastrophic failures, including explosions, oil fires, and damage to the transformer. Online DGA offers a proactive approach to bushing health monitoring, ensuring that potential issues are identified and addressed before they become critical.
Detection of Partial Discharge
Partial discharge (PD) is a localized breakdown in the insulation system of transformers. It can lead to gradual erosion of the insulation and eventual failure. Online DGA, in combination with the Dhruva S2TS, offers the advantage of measuring high-frequency signals to monitor PD activity. This added layer of protection ensures the safety and integrity of the transformer’s main tank.
