Thermal Imagery is the way of the future as regards maintenance routines. This is the most accurate, least invasive form of maintenance facility and it can be used on any electrical or electro-mechanical system to rapidly identify possible faults, and compile historical logs of components so that long term faults can be identified before they create catastrophic consequences.
Thermal Imagery can also be used in areas that you would not think of, such as insulation checks, gas leakage, verification of correctly torqued fastenings and many other fields.
Below are a few examples of how thermal imagery can be used to identify faults.
- MCCB contact in right hand side pole has clearly failed. Massive heat build up identified within the MCCB body - radiating slightly within its associated conductor.
- This hot wire would signify a connection which was not tightened correctly or has 'slackeded' due to expansion and contraction of conductor. Either way causing conductor to heat.
- Motor front end overheat, again showing possible bearing or seal fault.
- Extremely high heat build up identified within this motor. Clear fault signified as heat has radiated through the cooling casing of the motor.
- The beginnings of a possible fault is shown here. Motor front end has warmed to the high end of the temperature spectrum recorded. Posssible indication of bearings or mechanical seal failing.
- Bad termination of fuse to busbar. Only the fuse lug on busbar is showing as 'hot', with minor residual heat into fuse body.
- Fuse terminal has bad termination. Hot point is only at fuse clamping lug. There is residual heat in the fuse body and associated conductor but these dissipate quickly.
- Fuse body only has high heat build up. This signifies high resistance, fuse failing.
- Bends in the pipework are shown as 'hotter' as this is where the product within the pipes has to change direction and it is the physical interaction of the product and the bend that causes the bend to heat.
- This refinery vessel not only shows level indication, but demonstates that thermal imagery can be used to identify products of differing density within a vessel, the heavier in this example being red, the lighter yellow. The heavier product is denser and therefore contains more heat available per cubic metre - thus showing up hotter.
- This image shows a clear example of how thermal imagery can be used to identify vessel contents levels just by the temperature variation between the section of vessel containing product, to the section that isn't.
