Since the building of smart grid is proposed in China

the smart substation has made great development.As one of the important equipments

the smart high-voltage power equipment is characterized by measurement digitalization

control networking

state visualization

function integration and information interaction.Enterprises

research institutes have carried out their research

the results of these studies have been analyzed comprehensively

and it is shown that most of its production equipment is the simple superposition of the on-line monitoring of the high-voltage power equipment

they have different understanding of the smart high-voltage power equipment.In order to better develop the smart high-voltage power equipment and promote the construction of smart substation

the article introduces the differences between the smart and the traditional high-voltage power equipment in terms of structure

function division

integration level and transmission protocol with the concept of the smart high-voltage equipment.
