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 optional analogue inputs:
- 4 Analogue inputs 0/4 … 20mADC/6 Analogue inputs 0/4 … 20mAAC +20% or 0 … 80 VAC +20% (configurable by jumpers)
It is further equipped with digital outputs for the transmission of alarms or the execution of control functions (e.g. control of a cooling system of a transformer):
- 8 digital relay outputs /5 digital optocoupler outputs (Option)
