Hot spot monitoring in switchgear - Farsens Wireless Sensors spot monitoring in switchgear helps prevent accidents and electricity shutdowns. Some of the major issues in switchgears appear where busbars interfacing with other busbars or cables form poor connections. When that happens, junctions heat up causing further degradation of the connection, which may eventually fail.
