As Hydrogen (H₂) is involved in nearly every fault of the insulation system of power transformers and Carbon Monoxide (CO) is a sign of an involvement of the cellulosic / paper insulation the presence and increase of Acetylene (C₂H₂) and Ethylene (C₂H₄) further classifies the nature of a fault as overheating, partial discharge or high energy arcing. Oxygen (O₂) can be a sign of excessive ageing or leakages within the sealing of hermetic transformers. The device can serve as a compact transformer monitoring system by the integration / connection of other sensors present on a transformer via its optional analogue inputs:

• 4 Analogue inputs 0/4 … 20mADC
• 6 Analogue inputs 0/4 … 20mAAC +20% or 0 … 80 VAC +20%
