Infrared inspections are essential for having a thorough preventive maintenance program. Performing these inspections enables a business to detect potential problems long before they become a serious problem.By using equipment such as a thermal sensitive camera, hotspots are immediately visible during the electrical infrared inspection.Some Standards for an InspectionOne important element to conducting a successful inspection is to understand the standards that govern how best to assess the situation. Here are a few things that operators should consider.
Inspecting building envelopes – specific practices and procedures can specify and allow technicians to safely inspect building envelopes. This detects latent moisture, structure details and excessive loss of energy.
Inspecting insulated roofs – both aerial and ground based inspections can examine insulated roofing systems.
Pests and Pest-related damage – it is possible that some type of pest has invaded an area of the building where electrical wiring resides. Aerial and ground based examinations are also applicable to this type of inspection.
Training Courses to Perform Accurate InspectionsBefore inspections can be performed successfully a technician must receive proper training to know how to use equipment and what to check. Training courses offer the best path to accomplishing this by teaching technicians what they need to know.Generally, these courses cover typical electrical problems that may occur. Attendees also learn about the potential impact on a facility with a malfunction when a problem is not resolved. In addition to learning how to perform inspections, attendees will also learn safety and efficiency considerations, and the procedure for preparing reports.Examples of Learning ObjectivesTypical training courses focuses on a variety of areas in a building that can be affected by electrical problems such as
breakers and electrical distribution panels.Some examples of the learning objectives covered in the inspection training courses include:
Intro to thermal imaging systems that need inspections
Study of inspection methods for indoor and outdoor electrical equipment
Collection of quality data such as emissivity and distance when using infrared cameras
How to recognize thermal patterns of electrical faults
Severity criteria when conducting inspections
Accurately interpret thermograms to make informed decisions about different situations
Following good safety procedures for electrical inspections
Distinguishing between reflections and hot spots, and indirect versus direct readings
In many cases, inspection training is not a one-time deal. As the technology continues to advance, additional training will certainly be necessary.
