Infrared Inspections
Infrared inspections, also known as thermographic inspections or thermal imaging, involve using infrared cameras to detect and visualize heat patterns emitted by electrical components. Here are the key reasons why you should consider regular infrared inspections for your electrical equipment:
- Overheating
Issues:
Infrared inspections can detect overheating electrical components such as wires, switches, circuit breakers, and connections. Overheating is a common precursor to electrical failures and can lead to fires or equipment damage. Detecting these issues early can prevent catastrophic failures.
- Failure
Prevention:
By identifying and addressing potential issues before they escalate, you can prevent unplanned downtime in your facility. Downtime can be costly in terms of lost production, revenue, and repair expenses.
- Increase Equipment
Lifespan:
Regular inspections can extend the lifespan of electrical equipment. Overheating and electrical stress can accelerate wear and tear, leading to premature equipment failure. Addressing issues early can help equipment last longer.

TABLE
100.18
Temperature specifications vary depending on the exact type of equipment. Even in the same class of equipment (i.e., cables) there are various temperature ratings. Heating is generally related to the square of the current; therefore, the load current will have a major impact on ΔT. In the absence of consensus standards for ΔT, the values in this table will provide reasonable guidelines. An alternative method of evaluation is the standards-based temperature rating system as discussed in Chapter 8.9.2.2, Conducting an IR Thermographic Inspection, Electrical Power Systems Maintenance and Testing, by Paul Gill, PE, 2008 edition. It is a necessary and valid requirement that the person performing the electrical inspection be thoroughly trained and experienced concerning the apparatus and systems being evaluated as well as knowledgeable of thermographic methodology. |
