As most electrical equipment tends to fail because of degradation over time, this slow process can lead to excessive heat being created internally, which in turn often hastens the degradation, and worsens the situation. Thermographic Surveys help identify failing and stressed components early, allowing for strategic and preventative maintenance to be carried out ahead of time, thus reducing resultant plant downtime.

Surveys can monitor virtually any electrical circuit, connection, bearing, coupling, cable joint, switchboard, bus-bar or any other electrical component or piece of machinery or equipment. This will help you strategically target areas requiring preventative maintenance to achieve improved overall results and performance. An ITT survey can be used to target suspect equipment, or preferably, to provide a regular and comprehensive monitoring service on all plant and equipment. 

By using either spot testers or live thermographic imagers, we can record where excessive heat is being emitted. Various resolution and wavelength options are used to record heat signatures for either close-up surveys of indoor equipment, or external and long-range subjects. Following an onsite recording, the images are provided in a comprehensive report, allowing you to make informed choice about solutions to problem areas.

Benefits :

1. This will help you confidently plan and schedule preventative maintenance for electrical infrastructure.

2. By being able to foresee and fix trouble spots early, breakdowns can be avoided, and consequential loss in plant downtime and lost production can be reduced. 

3. The origins of perplexing and intermittent faults that keep troubling plant productivity again and again, may finally be identified and eliminated once and for all.

4. If your insurer values and rewards pro-active and pre-emptive measures to reduce risk, Insurance premiums may be reduced. 

5. The life span of expensive electrical components can be prolonged by ensuring they are protected from ongoing damage by excessive heat build up from within, or from other failing components.

Whilst most new plants are designed to strict specifications, problems in design, construction and workmanship are always possible. For this reason, a Thermographic Survey should not only be utilized for older or problem prone electrical components and infrastructure, but also for new plant and equipment. 
A Thermographic Survey on new plant and equipment will ensure commissioning has been carried out correctly, and may uncover any “day-one” problems brewing in the background. By identifying problems well within the warranty period, plant contractors may be more readily held accountable for substandard work or equipment. By identifying the problem before its consequences are fully felt, a quicker and more cost-effective solution should certainly follow.

For new plants, a Thermographic Survey at the time of commissioning (at full rated load) also gives you a base line for your equipment running conditions which can be used over time to track deterioration thru gradual energy load growth and normal lifespan.

A thermographic survey should also be performed before and after any major shutdown or overhaul to ensure that all faulty items have been rectified and no new faults have resulted from the overhaul. Depending on the criticality of your plant, you may wish to survey once or twice a year, maybe even more often, until you have enough information to optimise your survey frequency.

It should be noted that the survey can only detect where heat is present. The actual cause of the heat build-up can be as diverse as the plant itself. Your own informed understanding of your plant, or the expertise of a third party may be necessary for analysis beyond the recording and report.

Thermographic Surveys
Thermographic Surveys are a heat detection and recording service which helps owners of electrical infrastructure identify developing and hidden problems that are not yet visually apparent to the naked eye. This technology is a proven method of preventative maintenance, and will allow problems to be identified and solved before their full impact is felt.
