Design conformance review (DCR)

What to include with your application

• 

  A design drawing

  A geospatially correct design drawing of the subdivision plan.

  View example

  Subdivision plan design drawings shall be geospatially correct by incorporation of Map Grid of Australia MGA94 grid system. This geospatial information is required to enable incorporation into Western Power’s Geographic Information System (GIS). All drawings sent to Western Power must be in DGN format (Microstation - Bentley) and saved in Default View, as opposed to Sheet View, prior to submittal. 
   
  The MGA94 file should only include the pre-calculated cadastral plan of the current subdivision stage where Western Power asset are to be installed. If the MGA94 file is not provided with the submission for DCR, it is to be provided to Western Power through the electronic mail box External Design and Construct atby email least five working days prior to Handover inspection. The MGA94 file is required to be input into Western Power’s GIS data base so that the necessary switching and commissioning program can be produced for the energisation of the subdivision.

  LV Volt drop assessment

  This assesses that the voltage drop, line currents and fuse protection are adequate for each circuit. 

  Use our Low voltage design software to create an assessment.

• 

  Bill of materials

  The Bill of Materials must cover the materials which Western Power is to provide for the work agreed to be undertaken by Western Power.

  View example

  The Bill of Materials must cover the materials which Western Power is to provide for the work agreed to be undertaken by Western Power. It is to be based on compatible units contained in our Distribution Design Catalogue (DDC). It shall be in a format suitable for direct loading into Western Power’s DQM. 
   
  TXT file based on the DDC manual created from Microstation or DQM CU EXPORT FACILITY and generated by the DQM/CAD Interface – Urban Residential Design Software.

• 

  Voltage fluctuation report

  A report demonstrating that the voltage fluctuation occurring at your point of supply is within limits defined in SA/SNZ TS IEC 61000.3.5:2013  “Electromagnetic compatibility (EMC) Limits - limitation of voltage fluctuations and flicker in low voltage power supply systems for equipment with a rated current greater than 75 A”.

• 

  Earth potential rise (EPR) assessment

  An assessment that demonstrates an earth fault on the high voltage (HV) power network does not result in dangerous levels of a earth potential rise.

• 

  Streetlight authorisation letter

  Streetlights within subdivision developments is provided for the local government authority (LGA). Developers will generally install either Western Power standard streetlight or Western Power’s decorative streetlight. Energy consumption on Western Power standard streetlights will be charged to LGAs as per gazetted street lighting tariffs. Energy consumption on decorative streetlights will usually be higher than the gazetted tariff.

  Therefore, Developers are required to seek the approval of LGAs if they intent to install decorative streetlights in the subdivision developments.
