At Reliant Asset Diagnostics, we are committed to delivering precise, data-driven insights that help businesses safeguard the reliability and efficiency of their high-value electrical assets. Our core expertise lies in Dissolved Gas Analysis (DGA) and transformer diagnostics, and we are actively expanding into a full suite of electrical testing services tailored for today’s complex energy infrastructure.
With a deep foundation in utility-scale power generation—both renewable and non-renewable—we understand the critical nature of asset reliability across solar farms, wind facilities, and conventional power plants. Our real-world experience working alongside Independent Power Producers (IPPs), SCADA systems, and the maritime industry gives us a unique, versatile perspective that few diagnostic partners can offer.
Our approach is rooted in industry best practices and strict compliance with global standards, including IEEE C57.155-2014 and ASTM D3612, ensuring every test and analysis meets the highest levels of accuracy and trust. Whether supporting engineers, contractors, facility managers, or power producers, we provide the actionable insights needed for proactive maintenance, risk reduction, and long-term asset performance.
At Reliant Asset Diagnostics, our mission is simple:
To be your trusted partner in power system reliability, wherever energy flows—on land or at sea.
Why do Dissolved gas analysis on transformer oil
Transformer oil plays a critical role in both electrical insulation and heat dissipation within power transformers. During normal operation, the oil is subjected to high electrical stress, elevated temperatures, moisture ingress, and oxidation. Over time, these conditions lead to the degradation of insulating oil and cellulose-based solid insulation. This degradation generates diagnostic gases that dissolve into the transformer oil, including hydrogen, methane, ethane, ethylene, acetylene, carbon monoxide, and carbon dioxide. The type and concentration of these gases are directly related to developing internal faults such as partial discharge, thermal overheating, and electrical arcing.
This relationship forms the basis of dissolved gas analysis (DGA), a proven condition monitoring and predictive maintenance technique used throughout the power industry. By analyzing dissolved gases using chromatographic methods, DGA provides early detection of transformer faults, supports asset health assessment, and helps utilities and industrial operators reduce unplanned outages and extend transformer service life.
The chromatography method, first used in 1903 for studying plant pigments, eventually became widely adopted across various branches of chemistry, including gas chromatography.
Today, chromatographic dissolved gas analysis is favored due to several key advantages:
- Oil samples can be taken without disconnecting the transformer.
- The method is applicable for evaluating the condition of transformers as well as other oil-filled electrical equipment.
- It allows for the identification of a wide range of transformer defects.
- It detects issues at an early stage, which other methods may not identify.
- The method reveals not only the type of defect but also the extent of damage.
Since the 1960s and 1970s, DGA has been used for diagnostic evaluations of transformer health, with standards such as ASTM D3612 and IEC 60567 now governing its implementation.
