First pass check

9

✓ Do we already have a PoC for this site? ✓ Is there interactivity within this area? ✓ Is this site surrounded by heavily loaded network? ✓ Are there any other known issues in that area of the network? We will not undertake a full or thorough network study.

Network Information

10

Within our secure area of our website you can access:

  • Network Development proposals
  • Fault Level information
  • Load information
  • Transformer data
  • Circuit data
  • Schematic diagrams
  • Geographical plans
  • HV Network information
  • Distribution substation information

SLIDE 12

Standard Design Matrix

12

  • Code of Practise 226 – Low Voltage Network

Design Suitable for:

  • For 3 phase loads up to 60kVA
  • For single phase loads up to 20kVA
  • For new loads only
  • Motor loads included but not welding

equipment, disturbing loads, or loads typically known to contribute harmonic currents

  • Applies to urban networks only (all cable)

Final Checks

13

  • Connection less then 60kVA? YES
  • LV massing main 3c300WF all the way back to substation.
  • Distance from Substation less then 230m? YES
  • Service cable less then 30m? YES
  • Sufficient spare capacity on transformer? YES
  • All CP226 checks satisfied therefore connection

can be taken from the passing main without full network study.
