Detecting electrical unbalance and overloads
Electrical unbalance can be caused by several different sources: a power delivery problem, low voltage on one leg, or an insulation resistance breakdown inside the motor windings. Read more...

Inspecting electric motors
Using a handheld thermal imager, you can capture infrared temperature measurements of a motor's temperature profile as a two dimensional image. Read more...

Loose or corroded electrical connections
Thermal images of electrical systems can indicate the operating condition of the equipment in those systems. Read more...

Tests and measurements for electrical fire prevention
This article reviews the fundamental causes of overheating, as well as, the tests and tools commonly used to uncover overheating problems. Read more...

Monitoring transformers
Problems with surge protection and lightning arrestors leaking to ground and current tracking  over insulators can also be detected using thermography. However, finding such problems requires the capture of subtle temperature differences often under difficult-to-monitor conditions. Read more...

Pumps, fans and compressors
While many people in the power generation industry are familiar with annual infrared thermography surveys as part of PdM, the coal plant in this case study uses a thermal imager year round. There are two differences in their approach. Read more...

HVAC Air leakage inspections
In energy audits of homes and other buildings, technicians use blower doors in conjunction with thermal imagers. The blowers create positive or negative pressures within interior envelopes, making leaks much more apparent in thermal images. Read more...

Motor control centers
One set of tools for monitoring equipment in substations is Fluke's handheld thermal imagers. Thermal imagers capture two-dimensional representations of the apparent surface temperatures of electrical components and other objects. Read more...

Infrared inspecting for building and facilities maintenance
Surface temperature can tell you a lot about a building's structural elements, plumbing installations, and HVAC and electrical systems. Problems that are otherwise invisible to the naked eye are suddenly clear as day when you look through an infrared lens. Read more...

Electrical, insulation and thermal measurements for motors and drives
Most facilities need to get maximum life out of their motors, because they are expensive to replace in terms of both money and labor. Electrical, insulation resistance and thermal measurement are three tests that can troubleshoot motors, drives, and associated electrical panels and prolong their operational lifetime. Read more...

Applying infrared thermography to predictive maintenance
This document discusses the cost savings of thermal imaging (thermography) PdM, provides guidelines for successfully capturing and analyzing thermographic data and describes how to integrate thermography into a predictive maintenance program. Read more...

Why thermography is good for your business
Electrical contractors typically use thermal imagers for predictive maintenance and troubleshooting, and sometimes during installation. Read more...
