Primary and secondary power distribution systems (layouts explained)
Typically, a rural primary feeder supplies up to 50 distribution transformers, spread over a wide region but the figure significantly varies depending on configuration.

A typical primary distribution substation would include air-insulated outdoor-type high-voltage side (HV) and a metal-enclosed air-insulated indoor-type medium-voltage switchgear (MV).
Primary Service Standards
The high voltage substation and the high voltage lines feeding the substation are not considered part of the Primary Installation and are treated separately in these instructions.
TRANSMISSION AND DISTRIBUTION OF ELECTRICITY
The network of high-voltage power lines linking the power station to the cities, towns, rural and residential areas where electricity is used is called the national grid or interconnected grid.
