Transformer Monitoring - Online Dissolved Gas Analysers

A permanently installed multi-gas-in-oil analysis system with transformer monitoring functions. It allows for the individual measurement of Moisture in Oil (H 2 O) and the key gases Hydrogen (H 2), Carbon Monoxide (CO), Acetylene (C 2 H 2) and Ethylene (C 2 H 4) dissolved in transformer oil. This extra data from the HYDROCAL 1005 reduces the amount of maintenance time because the probable cause of any faults will have been established before action takes place.Get price
