The HYDROCAL 1005 Offshore is an online monitoring system permanently mounted on the transformer and is special designed for Offshore Wind Power Applications. It allows for the individual measurement of Moisture in Oil (H2O) and the key gases Hydrogen (H2), Carbon Monoxide (CO), Acetylene (C2H2) and Ethylene (C2H4) dissolved in transformer oil.
The HYDROCAL 1005 Offshore is specially designed for the harsh conditions (salt water, corrosion) on offshore platforms (e.g. offshore wind mill parks). A special painted housing with no window and the application of chrome nickel and stainless steel ensures the reliability and the persistence of the device.
The device can serve as a compact transformer monitoring system by the integration / connection of other sensors present on a transformer via its optional analog inputs:
• 4 analog inputs 0/4 ... 20 mADC
• 6 analog inputs 0/4 ... 20 mAAC +20% or 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 a cooling system of a transformer):
• 5 digital relay outputs
• 5 digital optocoupler outputs (option)
