Becoming a qualified thermographer can put you ahead of the rest!
Thermal imaging cameras are fast becoming an important tool for a multitude of applications, helping you identify weak spots and damage effectively. Not to mention, having a qualified thermographer on site adds value to your business.
Infrared radiation emitted from objects over a certain temperature can’t be seen by the human eye, thermal imagers however, can convert this infrared radiation into electrical signals, and present them as a thermal image so you can view and asses the heat of the object being monitored. Thermal imagers allow you to evaluate the heat status of low, medium and high-voltage systems effectively, so you can find anomalies before damage can occur. Thermography therefore minimizes dangerous fire risks and prevents costly production downtime.
Typical applications for thermal imagers in the electrical field:
Thermography in the inspection of switch cabinets
In electrical installations or cables, increased temperatures are always an indication of an overload, an imminent malfunction or an existing defect. Thermography is particularly useful in the maintenance of switch cabinets, as the measurements can be carried out non-contact and at a safe distance. Anomalies can therefore be detected, and counter measures can be implemented.
Maintenance of electrical installations: conductors and connections
Different temperatures in conductors and connections in electrical installations may be a sign of loose or corroded connections. As shown in the image, heat propagation is also monitored in the cable duct and bundled cables.
Thermography reports for Insurance
Insurance companies have embraced the technology in New Zealand and now call on all industrial companies to have a thermal report performed at least once per year. This is a great opportunity for electrical contractors to gain a qualification in this field and increase business potential.
Maintenance of electrical installations: electrical components
In the case of electrical components, heat distribution within the individual components is also significant, as well as the connections and access lines. Different temperatures within maintenance indicate the operating status but can also be indicative of a malfunction. The image shows an overloaded electrical fuse. It may be that this fuse is too small, or the electrical components are producing excessive current.
Maintenance of electrical installations: control and regulation systems
Control and regulation systems are operated at low voltage and can be inspected quickly and easily using thermography. These systems are normally maintained using thermal imagers with a high detector resolution. The higher resolution makes smaller details visible, so even the smallest electrical components can be analysed.
How can I become a qualified Thermographer?
Twice a year, Eurotec provide a 5-day workshop through which level 1 Themography Certification can be attained.
Thermography expert Jeff Erichsen from Advanced Infrared Resources Asia Pacific region is the course tutor, having learnt from the best, our previous tutor Wayne Ruddock, Jeff provides thorough and practical training courses with a hands on experience for each student, so they can effectively perform the infrared thermography tasks required once they return to their work place.
Next level 1 Course dates:
AUCKLAND (Eurotec Head Office, Penrose)
14th - 18thMay, 2018
$1950+gst per person
21st - 25thMay, 2018
$1999+gst per person
The Level 1 Thermography Certificate is a certification by The Australian & New Zealand Institute of Infrared Thermography.
