Transformer Gas Monitoring System
변압기 유중가스 분석 시스템
The HYDROCAL 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), Carbon Dioxide (CO2), Methane(CH4), Acetylene (C2H2), Ethylene (C2H4), Ethane (C2H6) and Oxygen(O2) dissolved in transformer oil.
Operation Principle
 • Miniaturized gas sample production based on headspace principle (No membrane, negative pressure proofed)
 • Patent-pending oil sampling system (EP 1 950 560 A1)
 • Near-infrared gas sensor unit for CO, C2H2, and C2H4
 • Near-Infrared gas sensor unit for CO2, CH4, and C2H6
 • Micro-electronic gas sensor for H2 and O2.
 • Thin-film capactive moisture sensor H2O
 • Temperatur sensors (for Oil and gas temperature)
