All types of incipient faults are covered by the monitoring of hydrogen gas levels. Slowly eroding

paper faults can be exposed through the monitoring of carbon monoxide. Various degrees of thermal

faults, including arcing, can be detected and identified, often leading to a transformer repair rather

then a much more costly transformer rebuild.

In particular, the TRANSFIX DGA 500 enables the well known Duval’s triangle DGA diagnostic

described in Appendix B of IEC Standard 60599. It uses the value of 3 gases (Acetylene, Ethylene and

Methane) and is suitable for identifying various degrees/temperature of thermal faults as well as the

presence of high-energy electrical discharge faults.

Key Benefits

• Ability to perform Duval’s triangle DGA diagnostic

• Easily replaceable with a full nine gas unit

• Communicates data to allow remote diagnostic

• No carrier or calibration consumable gases required

• Available with AC or AC/DC power supply
