  • Page 3: General Description

    GENERATION NITROGEN GENERATOR SYSTEM MANUAL GENERAL DESCRIPTION The N2 Nitrogen Generator is designed for use on tap changers, breakers, main tanks or any other electrical device requiring a gas-blanketed enclosure. The unit produces nitrogen by separating oxygen from compressed air by means of hollow fiberglass separation membranes. The compressed air is supplied by an on-board compressor and the generated nitrogen (N2) is fed to internal storage vessels.

  • Page 24 If the compressor is running with the protective circuit forcing a cool down period, steps MUST be taken to find the cause for the excess of one liter/minute gas usage. Normally, the cause for the excessive N2 gas usage will be a leak in the protected volume being supplied by the N2 Generator.
