Thermal Imaging of electrical supplies, systems and components gives an immediate identification of temperature anomalies. Loose terminals, poor contact condition and overload are typical examples of faults producing local temperature differences.
Experienced interpretation of the Infra-red images help diagnose the root cause of the problem and its rectification.
The inspection technique is a reliable, safe and efficient means of confirming electrical integrity.
Below is a typical example of electrical fault found using thermal imaging, here the bottom fuse connection is 180C+ and urgently needs re-making to avoid failure.
An example of a low voltage terminal rail showing a loose connection, the fault is open-circuit on control wiring.
Bus chamber below switch showing a heat source, internal inspection recommended, see below for result.
Red phase connection to bus-bar almost 300C! Found to be very loose.
Fault avoided: Power failure and potential fire hazard.
Off-shore example of sand deposits showing in seperator, colder area at base shows levels of solids.
Example of deteriorating lagging on cryogenic pipework showing cold spots on surface.
Example showing colder bolts, these were found to be loose. The flainge is on a high pressure crude oil discharge line and could have failed if not detected.
