The main characteristics of an MV power supply are:

  • The nominal voltage
  • The short-circuit current
  • The rated current used
  • The earthing system

The characteristics of the MV network determine which switchgear is used in the MV or MV/LV substation and are specific to individual countries. Familiarity with these characteristics is essential when defining and implementing connections.
