Change Routes with the Season

Mon, 09/18/2017 - 14:29
Traditionally, many facilities perform infrared inspections on an annual basis. While this approach may detect deficiencies within operating systems, systems not under load due to seasonal or operational conditions cannot be effectively inspected.

Point Radiometers & Spot Measurement Size

Sun, 09/10/2017 - 09:39
With awareness of infrared technology at an all time high, point radiometers have become a common tool in many areas. Frequently, knowledge of proper operation lags behind instrument popularity. Understanding how spot measurement size affects accuracy is imperative to collecting meaningful data.

Infrared Inspections of Lightning Arrestors

Sun, 09/03/2017 - 10:21
Infrared thermography is a proven technology for detecting defects in electrical circuits that are under load. Thermal imaging can also be used to detect defective lightning arrestors that are leaking current to ground.

Are Electrical Switchgear Surveys Still the “Low-Hanging Fruit” of Infrared Thermography?

Fri, 09/01/2017 - 14:58
This paper discusses the market forces, insurance requirements, government regulations and risk management thinking that are changing the electrical testing industry in general, and the electrical infrared testing application in particular.

School’s Open – Drive Carefully

Mon, 08/28/2017 - 15:00
By early September, over 55 million children across the United States will head back to school.

Blinded by the Light

Mon, 08/21/2017 - 14:36
While it is often interesting to use a thermal imager to view ordinary objects, imaging the sun, arc welders and similarly hot objects should be avoided unless your imager has been built specifically for these applications.

Imager Operational Check Prior to Inspections

Mon, 08/14/2017 - 06:02
Many infrared applications standards require that infrared test equipment be within calibration prior to the conduct of an inspection.

Temperature Limits for Drive Belts

Sat, 08/05/2017 - 16:59
Temperature is frequently used to gauge the condition of motors and power transmission equipment. In this Tip, we discuss the effect of heat on flexible drive belts and temperature limits for them.

Pricing Infrared Inspection Services

Sun, 07/30/2017 - 08:54
A well-known Zen riddle is, “What is the sound of one hand clapping?” A perpetual thermographer’s enigma is, “What are infrared inspection services worth?” This week’s Tip addresses some key considerations when evaluating prices for infrared inspection services.

Infrared Inspections of UPS Systems

Mon, 07/24/2017 - 15:36
Uninterruptible Power Supply (UPS) systems are commonly found in facilities where reliable electrical power is critical. Infrared inspections can play a key role in maintaining these crucial systems.

Post Processing Thermal Images

Sun, 07/16/2017 - 15:42
Post processing of thermal images is a common practice for many thermographers. While image processing may provide a measure of convenience for some, it can have significant drawbacks.

Roof Inspections – Solar Reflectance versus IR Reflectance

Mon, 07/10/2017 - 14:57
Energy and environmental concerns have caused many facility owners to look to their roofing systems for ways to conserve energy. Modern roofing systems known as ‘cool roofs’ can provide savings; however, they can present challenges for thermographers who inspect them.

Ensuring Accurate Measurements with Point Radiometers

Wed, 07/05/2017 - 15:18
Point radiometers, also known as infrared thermometers, have become a common tool in a variety of workplaces. Portability and instantaneous results are two of the many benefits that these instruments provide.

Making Your Own Blackbody Simulator

Sun, 07/02/2017 - 10:54
Blackbody simulators are essential tools for checking the calibration of infrared imagers and radiometers. One alternative to purchasing a blackbody simulator is to make your own.

Using Tmax Corrected Formula to Prioritize Electrical Exceptions

Sat, 06/24/2017 - 08:38
For decades, temperature measurement has been used to gauge the operating condition of electrical components.

Infrared Training – Why it Isn’t All the Same

Sun, 06/18/2017 - 08:42
With interest in thermography at an all-time high, more people are seeking training and certification. When comparing infrared course offerings, many mistakenly assume that all training and certification courses are the same.

Warm Lighting Circuit Breakers

Sun, 06/11/2017 - 08:40
When performing infrared inspections of branch circuit panels, lighting circuits will often appear warmer than adjacent circuits. If adjacent circuits are lightly loaded, the warmer circuits may be indicative of a normal condition or they may represent a more serious condition.

Does Thermography Really Save Time and Money?

Sun, 06/04/2017 - 09:14
Whether you work as a professional thermographer or are setting up an in-house infrared inspection program, it is important to accurately represent the benefits of thermography to prospects or peers. Failure to do so can lead to unrealistic expectations and disappointment.

Steam Trap Inspection Basics Using Ultrasound

Thu, 06/01/2017 - 15:05
High energy prices and global competition dictate a need to reduce energy waste and improve system efficiencies whenever possible.
