Product Overview

The TRANSFIX™ DGA 500 is an on-line monitoring unit that measures individual dissolved gas and

moisture and provides both on-line monitoring and key exploratory diagnostics. It uses the now

well known PAS technology (Photo Acoustic Spectroscopy) made popular due to its accuracy,

repeatability and lack of consumable through its bigger brother the Kelman™ DGA 900.

When a transformer’s insulation system is overstressed, gases are produced that dissolve in the

transformer’s insulating oil. Dissolved Gas-in-oil Analysis (DGA) and moisture measurements are

recognized as the most important tests for condition assessment of transformers and the best early

indicators of developing faults.
