Preparing for IR Inspections of Electrical Systems

Perhaps the most common application for infrared thermography is PdM inspections of electrical distribution systems. However, in focusing on the inspection, many overlook the critical step of properly preparing for the inspection.

Proper planning prevents poor performance. For IR inspections of electrical distribution systems, this planning should begin well in advance of the inspection. The following are some of the not-so-obvious considerations that should be part of every inspection.

• Performance standard(s) or Guidelines to be followed
• Safety standards and rules applicable to the work areas
• Thermographer and qualified assistant(s) should be trained as qualified persons as defined by NFPA and OSHA standards
• Necessary Personal Protective Equipment including fire resistant clothing
• Provisions for First Aid and CPR
• Pre-job safety briefing prior to the commencement of the inspection

Lastly, infrared inspections should only be performed by experienced, certified infrared thermographers who thoroughly understand the theory and operation of electrical distribution systems. Properly planning for your next infrared inspection can provide for a safer and more efficient inspection.
