Transfix 1.6

Transformer DGA monitoring unit

The TRANSFIX is a 9-gas on-line transformer DGA monitoring unit. Using specially developed advanced photo-acoustic detection technology, the TRANSFIX measures all significant fault gases (in ppm) as outlined by international standards as well as moisture in oil (%RH & ppm). The measurement of these gases allows the user to detect and diagnose a complete range of transformer faults.
