Decrement factor is used to get the rms equivalent of the asymmetrical current from the rms symmetrical current.

Split factor is to determine how much of the return ground fault current flows through the ground (causing earth voltages), and how much flows through shield wires and neutral conductors.

There are several "corrective factors" used in simplified hand calculations of step- and touch-potential. Kh corrects for grid depth, Ki corrects for grid geometry, Kii corrects for corner meshes.
