As Hydrogen (H₂) is involved in nearly every fault of the isolation system of power transformers and Carbon Monoxide (CO) is a sign of an involvement of the cellulosic / paper isolation 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.

The device can serve as a compact transformer monitoring system by the integration / connection of other sensors present on a transformer via its analogue inputs:

• 4 analogue inputs 0/4-20 mADC
• 6 analogue inputs 0/4-20 mADC +20% / 0-80 VAC +20%

configurable by jumpers It is further equipped with digital outputs for the transmission of alerts or the execution of control functions (e. g. control of the cooling system of a transformer):

• 5 digital relay outputs
• 5 digital optocoupler outputs
