Connection to the MV utility distribution network
At present there is no international agreement on precise limits to define "medium" voltage.
Voltage levels which are designated as "medium" in some countries are referred to as "medium" in others.
In this chapter, distribution networks which operate at voltages of 1,000 V or less
are referred to as Low-Voltage systems, while systems of power distribution which
require one stage of stepdown voltage transformation, in order to feed into low voltage
networks, will be referred to as Medium- Voltage systems.
For economic and technical reasons the nominal voltage of medium-voltage distribution systems, as defined above, seldom exceeds 35 kV.
