Infrared thermal cameras are a great additional to a preventive maintenance program. They’re easy to use and can help you find where issues are within your electrical system. Thermal cameras often have a point-and-shoot design with the IR image displayed on a screen on the back of the camera. Other cameras offer a more camera-style design that often has an articulating camera lens so you can point it exactly where you need to scan.

Choosing a camera with the right features for your needs can help make sure your preventive maintenance program works smoothly. Some cameras, like the Fluke Ti401 PRO thermal camera, offer a combination view where you can increase or decrease the intensity of the thermal image overlaid on the visible image.

Diagnosing issues

Infrared cameras can capture thermal information without touching the target, making them a good choice for inspecting the integrity of electrical systems from a safe distance to diagnose

• unbalanced loads
• possible harmonics issues
• overloaded systems with excessive current
• loose or corroded connections that cause increased resistance in the circuit
• winding insulation failure in electric motors
• component failure
• wiring mistakes
• underspecified components

When performing thermal scans, it’s important to keep a few things in mind: what you’re scanning, what a thermal camera can see, and load requirements. An electrical system can have hundreds of different pieces of equipment. Starting with the utility electricity production, high voltage distribution, switchyards, and substations flowing through the end with service transformers, breakers, meters, switchgear, and appliance panels. Using a thermal infrared camera to help with maintenance can help pinpoint where an issue is within an electrical system.

Inside electrical cabinets

Infrared cameras cannot see through electrical cabinets, or around solid metal. Whenever possible either open enclosures or install IR windows throughout your facility. IR windows are permanently installed into panels or cabinet doors to allow for a thermal camera to screen inside without needing to open the door.

If you are unable to open the cabinets or panels during a preventive maintenance walkthrough, make sure to note any doors with abnormally high temperatures on the outside surface of the enclosure. When that temperature is raised, it’s usually higher, much higher, on the inside of that encloser. Circle back with proper personal protective equipment (PPE) and investigate further in those cases.

Load requirements

When walking through your facility making thermal scans, it’s important that the systems you’re checking are under load. Complete your inspections at peak loads, worst case scenarios, or when the load is at least at 40%, as NFPA 70B suggests.

The heat generated by loose connections or overloaded circuits rises as the load does; the higher the load, the easier it will be to spot the problems. And don’t forget to take into account any cooling effects of wind, air conditioning, or other air movement.

Common issues thermal cameras can spot

Additional heat can be the first sign of an issue in an electrical system. Thermal cameras allow you to catch those temperature spikes before they wreak havoc, as long as you know what you’re looking for in a thermal scan.

When current flows through a circuit, part of the energy is converted into heat; this is normal. But when there is abnormally high resistance or current flow, the amount of heat generated is above and beyond the normal amount. Not only is this wasteful, but it’s also potentially damaging to assets.

Thermal cameras enable you to see the heat signatures that come along with high electrical resistance long before the circuit heats up enough to cause an outage or explosion. There are two basic thermal patterns related to electrical failure. Look for a high resistance caused by poor surface contact, or an overloaded circuit or multi-phase imbalance problem.

Poor surface contact

A switch or connector contact that isn’t secure may be producing additional heat to get enough current flowing through. Thermal imaging can catch when those connections are heating beyond the normal so you can make sure they’re fixed before damage is caused. Be aware that the point of heading may be very small in these kinds of situations, sometimes less than 1/16" when the problem first begins.

Conducting regular preventive maintenance routes and scanning the connections throughout a facility is important to catch a heating issue early. Some of those problems may show up quickly and need immediate attention. If left with additional heat for too long, the plug or switch can sustain damage, or the asset itself may be damaged.


Overloaded circuit

Overloaded circuits are another common problem to watch out for, whether it’s a total panel overloading and requiring immediate attention, or even circuit breakers overheating showing that the entire electrical system needs to be redone. Using a thermal camera, you can pinpoint the different temperatures above ambient across a panel. Even if the wires appear blue in an infrared scan, they may still be above room temperature, which shows a problem that should be investigated.

As with contact issues, an overloaded circuit can be a smaller piece of a scan. If you’re looking at one line of a controller that is hotter than the others, you’ll know there’s something wrong that needs further investigation. Doing regular thermal scans, not only to look for hot spots, but to compare the thermal images over time, can help you catch these kinds of issues before they seriously impact the asset or utility bills.

The Beard and the Respiratory Protection MaskHalf-masks and full-facepiece respirators require an optimal seal to guarantee their effectiveness, and the beard can impede it considerably.

DID YOU KNOW THAT A BEARD’S REGROWTH AS LITTLE AS ONE DAY OLD CAN AFFECT THE MASK’S SEAL IN PLACE?

What does it mean exactly?

Since many masks have been tested on different face types, the results of these tests vary considerably. However, it should be noted that in 100% of cases, after 7 days without shaving, the respiratory protection masks showed a leak of more than 1%. This means that the air inside the mask contained more than 1% of unwanted particles!
