Infrared Inspection FAQ
Infrared thermography is used to perform Pd/Pm inspections on electrical equipment because excess heat is usually the first sign of trouble on electrical (or mechanical) apparatus.
An infrared camera creates an image by converting radiant heat energy into a signal that can be displayed on a monitor (and later printed). The infrared energy emitted from an object is directly proportional to its temperature. Therefore temperatures are accurately measured by the infrared camera.
Electrical installations deteriorate with age and use. They should be inspected and tested at regular intervals to check whether they are in a satisfactory condition for continued use. Electrical boxes and systems should have periodic safety checks and inspections as part of an overall maintenance plan.
Periods between subsequent inspections will depend on the condition of the installation at the time of the preceding inspection,. I is recommended that periodic inspection and testing is carried out at least every five years.
