    MSDGA-I on-line monitoring system of gas in transformer oil realizes the fine analysis of transformer oil by gas chromatography, which has the characteristics of accurate measurement, fast analysis and real-time monitoring. The monitoring system is mainly used to measure and analyze the trace fault gas contained in the insulating oil of oil-immersed power equipment, and can capture the potential fault information of transformer equipment in real time to ensure the reliable operation of transformer equipment.

    Product features:
    Technical indicators Dynamic headspace plus vacuum double degassing principle;
    Full range linear sensor, full range linear from low concentration to high concentration;
    The detection cycle is short, and a set of detection data can be produced in 1 hour;
    The detection sensitivity is high, and the minimum detection limit of C2H2 dissolved in oil can reach 0.1ppm.
    It can detect more than six kinds of gas and micro water content in transformer oil, such as H2, CO, CH4, C2H2, C2H4, C2H6, CO2, etc;
    The unique constant temperature system ensures the repeatability and stability of the system analysis;
    Forced circulation of oil pump, timely detection, no dead oil sample;
    Can be integrated iron core, clamping parts leakage current integration;
    Intelligent fault analysis system, all-weather unattended;
    Support TCP/IP network protocol, support network remote function.

    Performance indicators:
    Detection cycle: minimum 2 hours, the longest detection cycle set arbitrarily.
    Data storage: ≥ 10 years.
    Degassing method: dynamic headspace vacuum double degassing.
    Carrier gas mode: 2 8L high purity air cylinders or self-contained air source generator (optional)
    Alarm setting: each gas concentration overrun alarm.
    Output results: hydrogen (H2), carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), ethane (C2H6), ethylene (C2H4), acetylene (C2H2) and total hydrocarbon values and their concentration spectra, preliminary diagnostic results such as three-ratio values, David's triangle, historical data trend charts, etc., leakage current of micro-water, iron core and clip, etc. are selected according to customer requirements.
