HYDROCAL 1008 is a permanently-installed multi-gas-in-oil analysis system with transformer monitoring functions. It allows for the individual measurement of moisture and the key gases hydrogen (H2), carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), acetylene (C2H2), ethylene (C2H4) and ethane (C2H6) dissolved in transformer oil. 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 it’s analog inputs: • 4 analog inputs 0/4-20mADC • 6 analog inputs 0/4-20mADC / 0-100VAC configurable by jumpers It is further equipped with digital outputs for the BM-HC1008/3
