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%
