Thermographic Surveys: Finding Electrical Faults Before They Find You
How to plan, carry out safely and act on thermal imaging surveys of switchgear, MCCs, drives and motors in UK food factories.
Why this matters in UK food manufacturing Loose connections, overloaded cables and failing components get hot long before they fail. A thermal camera shows that heat, so faults can be fixed in a planned stop instead of during a breakdown or a fire. Electrical faults are a leading cause of fires in UK industrial buildings, and many insurers ask food sites for an annual thermographic survey of main switchgear. In plain English A thermal camera takes a heat photo. A good electrical joint stays cool. A loose or corroded one gets hot, sometimes 50°C hotter than the one next to it. Spot it on the camera, tighten or replace it on a planned stop, and you have avoided a breakdown or a fire. 1.
