Thermal imaging of switchboards is used to detect potential electrical faults before they become a hazard. This is done by identifying any hotspots that are present in the switchboard. Hotspots are areas of the switchboard that are producing more heat than the surrounding areas. These hotspots can be a sign of an underlying problem such as a faulty connection, overloaded circuit, or defective component. Thermal imaging can help detect these problems before they become a safety hazard or lead to costly repairs.
