The Role of Thermography in Preventative Maintenance

Thermographic imaging is associated with pre-natal scans and military applications, and clients are sometimes surprised to see it applied by an electrical contractor in Surrey. But, preventative maintenance is one of the most important commercial electrical services on offer, and thermal imaging is a vital part of that.

A thermographic camera works in the infrared spectrum – detecting heat and producing images called thermograms. As long is something is above absolute zero, it will have a heat signature, which means that it is possible to create clear thermal images in the total absence of light, hence the security and military applications of this technology. Different settings can alter the range of sensitivity – just like focus, as well as detecting how well a particular medium (such as air or plaster) is transmitting heat – akin to a light meter. Images can look at the detailed function of individual circuits and video footage can be used to assess entire stretches of production equipment in real time, assessing for friction and stress. This kind of imaging is also handy in assessing our work with refrigerated units.

Preventative thermographic assessments can also support areas that are vulnerable to spikes and supply surges and areas of gain, or spot overheating in joints, fuses, or switches. Vancouver fire departments will thank you for doing so. The technology is used by firefighters themselves, to search for people and sources of fire. Thermographic reports can also be used to negotiate insurance premiums and, in the event of any claims, provide evidence of a high level of maintenance by skilled electrical contractors. Creating and maintaining a safe electrical infrastructure requires this level of oversight, but pays in the long run. Preventative surveys also mean less down time for repairs, a safer working environment, IT equipment that lasts and protection against data loss in the event of a power outage. Other benefits include efficient insulation, and by extension, lower costs.
