I’m often asked about Reduction factors or ‘Split factor‘ when looking at Earthing Designs. So what do these factors refer to? Why are they necessary? And when should you apply them?
What is a Split Factor (or Reduction)?
In Earthing terms, the Split Factor can be defined as the ‘split‘ or proportion of fault energy that chooses to use soil conduction as its preferred route back to the source, compared with how much of the energy takes alternative route(s). Alternative routes could be the cable sheath arrangements, CPCs or any other conductive structures intentionally or unintentionally bonded.
