Understanding the Significance of Dissolved Gas Analyser
The Heart of Transformer Health
Transformers are engineered to operate efficiently and reliably for decades, and they play a pivotal role in the power distribution network. These intricate devices are, however, susceptible to various forms of degradation, which can compromise their performance and longevity. One of the primary challenges faced in transformer maintenance is the detection of incipient faults and the prevention of deterioration or damage to the insulation system. Transformers operate in demanding environments, subjected to electrical, thermal, and mechanical stresses, and over time, the materials used in their construction can experience degradation.
The Role of Transformer Oil
Transformer oil, also known as insulating oil or dielectric oil, is an integral component of transformers. It serves as both an electrical insulator and a coolant, ensuring that the transformer operates at a safe and efficient temperature. Over time, the oil can interact with various materials within the transformer, and if any of these materials degrade or break down, they can release gases into the oil. These gases can be indicative of a fault or issue within the transformer.
Preventing Catastrophic Failures
The consequences of a transformer failure can be substantial. In addition to the cost of repairing or replacing the transformer, there can be collateral damage to other electrical equipment, potential harm to personnel, environmental claims, and regulatory fines. Hence, there is a pressing need to implement preventive measures and early warning systems that can identify issues in their infancy. This is where dissolved gas analysis becomes an invaluable tool.
The Science Behind Dissolved Gas Analysis
Decoding the Gases
Dissolved gas analysis (DGA) is a technique used to monitor the health of a transformer. It involves the identification and quantification of gases dissolved in the transformer oil. The most significant gases generated as a result of oil and paper insulation decomposition in the presence of faults are:
- Hydrogen (H2)
- Methane (CH4)
- Ethane (C2H6)
- Ethylene (C2H4)
- Acetylene (C2H2)
- Carbon Monoxide (CO)
- Carbon Dioxide (CO2)
- Oxygen (O2)
- Nitrogen (N2)
The quantities of these gases dissolved in transformer oil can vary significantly depending on the type and severity of the fault condition. These fault conditions can include arcing, partial discharge, overheating, low-high temperature hot spots, and more.
A Window into Transformer Health
Dissolved gas analysis provides a direct insight into the condition of the transformer. The presence and concentration of specific gases can act as diagnostic markers for various fault types. By continuously monitoring and analyzing the composition of gases in the transformer oil, it is possible to detect emerging issues before they escalate into critical failures.
Process of Analysis
The Dhruva S2TS Dissolved Gas Analyser utilizes gas chromatograph (GC), a widely recognized analytical technique, for the detection and identification of dissolved gases. The analysis involves the separation, identification, and quantitative determination of these gases. This process is highly accurate and can provide insights into the type and severity of any faults or deteriorations in the transformer.

The Power of Early Detection
The primary goal of the Dhruva S2TS is to enable early detection of impending issues within the transformer. By analyzing the gases dissolved in the transformer oil, the system can detect incipient faults and alert personnel to fault conditions at an early stage. This timely information is invaluable, as it allows for preventive measures to be taken to arrest further deterioration and damage to the transformer’s insulation.
Gas Chromatography Method
The Dhruva S2TS utilizes gas chromatograph, a highly precise and reliable method for gas analysis. Gas chromatography involves the separation of gas components based on their chemical properties and their subsequent identification and quantification. This method is well-suited for the detection of dissolved gases and the identification of incipient faults in transformers.
