Since the application of on-line monitoring technology

the technology is made greater progress

but its application has great blindness

and the practical effect is not ideal. In this paper

through the methods of investigation and study

the actual application demand and existing problems of on-line monitoring equipment in the various units are fully collected; the extensive investigation of current research status are carried out

from switchgear manufacturers

on-line monitoring equipment manufacturers

universities

research institutes at home and abroad. On this basis

the significance of on-line monitoring of high voltage switchgear and causes of the existing problems are analyzed

the new framework of on-line monitoring equipment is discussed

the research strategy at present high voltage switchgear on-line monitoring parameter requirements and on-line monitoring technology are proposed.
