About Thermography

Certified Thermographers using infrared imaging systems are a key component of comprehensive Predictive & Preventative Maintenance Programs

From reduced production to reactive repairs, unplanned downtime hurts everyone in the company. Thermography detects the thermal signatures of problems before they become a failure issue and allows for non-invasive analysis of a wide range of facility processes and equipment.

Thermography enables the work to be conducted while a facility is online, preventing costly interruption of plant operations

Programs that consistently use Infrared Thermography (IR) limit downtime by preventing unplanned shutdowns and by streamlining repair and maintenance planning. The resulting cost-saving and safety benefits of this type of examination include energy savings, the protection of equipment and capital investment, reduced insurance premiums, quick pinpointing and providing a diagnosis of problem areas, as well as establishing repair priorities based on severity and the critical nature of the item being inspected, and setting quality standards.

Electrical inspections are the most common and practiced infrared application

The benefits are obvious since electrical failures can easily cause personal injury and even death, equipment damage, material loss, as well as costly downtime.

Making sure your readings are informative with knowledgeable thermographers

One important factor is the load on a component. The load on the item being inspected will exponentially affect the current draw on a circuit and the resulting temperature rise. A small temperature difference under a load of 1A may be critical under a load of 20A. There are still many maintenance personnel and professional Thermographers who do not correlate load and temperature rise this can result in very miss informing information, and this can cause a false sense of confidence when serious problems still exist. The load or temperatures are not always referred to in the following samples, but that information was used in determining the criticality of the faults.

The value of thermography and predictive maintenance programs

It is also important to understand the theories involved in how infrared radiation works and how heat transfer are affecting the objects in a thermal image. Concepts such as Emissivity, thermal reflections, thermal conductivity, and indirect temperature measurement are crucial to the identification and diagnosis of electrical problems.

Although infrared electrical inspections are often carried out for insurance purposes, a thermograph’s true value is being an integral part of a predictive maintenance program. Combined with other skill sets which our people possess along with Thermography, this service will show cost benefits that will vastly outweigh the costs of inspection.
