    What are the preparations for switchboard surveys?

  • #2

    Switchboard Survey:
    • Thorough cleaning internally and externally at switchboard, when all generators are stopped and their prime movers locked off.
    • Main bus bar and their connections checked for tightness.
    • Bus bar supports, checked for damage due to insulation material.
    • Overheating signs at connection junctions, due to loose joint.
    • Internal wiring securely fixed.
    • Cable entries at switchboard bottom, sealed with non-flammable material.
    • Earth bar, securely bonded to both frame and to the ship hull.
    • Hinged panel door bonded with an earth strap to main switchboard frame.
    • Insulation resistance of each terminal measured.
    • Voltmeters, Watt meters and Ammeters calibrated and tested.
    • All trips tested [Safety devices].
    • Synchronizing test [load sharing] demonstrated.
    • Earth lamps checked
    • Automatic circuit breakers (ACB) and Automatic voltage regulator (AVR) tested.
