·Offshore version The Hydrocal 1005 is a permanently installed multi gas in oil analysis system with transformer monitoring functions.

·It individually measures Moisture in oil (H2O) and the key gases Hydrogen (H2), Carbon Monoxide (CO), Acetylene (C2H2) and Ethylene (C2H4) dissolved in the transformer oil.

·Especially 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 Hydrocal 1005 offers as a compact transformer monitoring system by the integration of other sensors present on a transformer (TCU Transformer Control Unit and / or bushing monitoring).
