Power transformers are crucial for ensuring a trouble-free supply of power with no interruptions. As reliable, rugged key components, they are frequently in use for decades at a time – and are thus subject to the unavoidable effects of aging and wear.
How can you plan your expenditures in a targeted way, and systematically control the timing of new investments? How can you avoid unforeseeable outages and minimize planned downtimes? And how can you reduce the impact on the environment while maximizing transformer availability?

- Why GAS-Guard 8?
- Analytical tools
DGA is the single-most comprehensive tool for transformer condition assessment
The current environment of higher loading on aging transformers, deferred capital expenditures on new equipment and increased service reliability requirements have driven the industry to investigate the use of innovative transformer condition assessment and management tools. As transformers age, they endure various stresses that can contribute to a variety of failure mechanisms. Appropriate online DGA monitoring and diagnostic tools can help utilities avoid unplanned failures, lower maintenance costs and extend transformer useful life.
Many transformer failures can be prevented through analysis of DGA data
Gas chromatography (GC) has long been the accepted standard for the measurement of dissolved gas levels in transformer oil. The GAS-Guard 8 provides accurate and repeatable measurement of the eight critical fault gasesas well as other significant parameters.The GAS-Guard 8 brings the DGA laboratory to your transformer with its rugged, closed-loop gas chromatograph. The GAS-Guard 8 packs this science into a compact package designed to be mounted on or near the subject transformer.
Key benefits include:
- Turnkey Installation & Replacement
- Assembly, Vacuum Oil Fill, & Testing
- Bushing & Cooler Changeouts
- Relocation
- Regasketing, Leak Repair
- Oil Filtration & Refurbishment
- Load Tap Changer Maintenance
- Condition Assessment
- Monitoring Systems
- Spare Parts Management
Through chromatography, the GAS-Guard 8 generates individual measurements of eight critical fault gases found in transformer oil. Accuracy is commensurate with traditional lab results. The sensor continually collects oil samples as often as every two hours. TheGAS-Guard 8 can also measure moisture in the oil, oil temperature and ambient temperature. DGA results and other measurement data are date/time stamped and can thus be correlated to transformer load.
Compehensive data requires powerful analytical tools
The software package included with the GAS-Guard 8 sensor allows the user to graphically display continuous gas evolution for each of the eight critical fault gases as well as moisture, load and ambient temperature. It also allows the user to trace changes in fault severity over time through dynamic plots created using the Duval Triangle and Rogers Ratios analysis tools.
