SF6-Air sensor module for Very High Voltages

SF6-Air sensor module for Very High Voltages

The high voltage GIS for voltages of 72.5 kV and above are essentially two-pressure systems for non-availability of vacuum interrupters in this high voltage range. In gas insulated sub-stations, modular components are assembled together to form the desired arrangement for a section or a bay.

  • SF6 gas measuring devices – Synergy Power Systems

    The SF6 Multi Analyser is a user and maintenance-friendly device which guarantees high measuring accuracy. First of all, the gas is checked for decompositions products. If critical SO2 values are determined the measurement can be interrupted. In case of contaminated SF6 the complete measuring gas can be recovered from the internal vessel.

Moreover the number of power interruptions can be reduced to a great extent if we set up a G.I.S substation in Kollam city. With the existing system voltage drop is also very high which can be minimized if the proposed system is set up.
