High-voltage switchgear busbar lap surface fiber-optic temperature measurement technology analysis and manufacturers selection guide

Busbar (copper row) lap surface is the “throat” part of the power transmission and distribution system, and its contact state directly determines the efficiency and safety of power transmission. In this paper, we analyze the micro-mechanism and evolution of busbar lap surface heating, and elaborate the technical barriers of fluorescent fiber optic temperature measurement technology in solving the problem of busbar overheating monitoring and ...
