Documentation Requirements for change of level applications

                                                                2



The drawings shall be based on a survey of the Energex assets which shall be carried out by a
licenced surveyor. The survey shall include the following:
     Profile of the ground along the line of the lowest conductor(s)
     Any ground features higher than the general surroundings in the vicinity of the conductors
     Ground level at the base of the Energex structure
     Conductor and insulator attachment points
     Minimum of 5 points along the length of the catenary(s) and the ground level below
     Time and date of the survey
     Ambient weather conditions including
           o Temperature (in shade)
           o Wind speed
           o Cloud cover (sunny, some cloud, overcast, rain etc)

The drawing shall show the conductor at its maximum operating temperature (in profile) and show
the blowout condition in plan (500Pa wind at 35degC).
Energex will supply the developer with:
      The type of conductor
      The feeder load at the time of the survey
      The maximum operating temperature of the feeder

The electrical calculations shall be carried out by an appropriately qualified RPEQ to determine
the conductor position at maximum operating temperature and the conductor blowout.

The drawing(s) shall contain a table of survey points and a table showing:
    Time and date of survey
    Feeder Load at time of survey
    Ambient weather conditions at time of survey
    Conductor type
    Maximum Operating Temperature
    Calculated tension at 15Deg C

The drawing(s) shall be signed by the RPEQ.
