Many predictive maintenance (PdM) programs use thermography to monitor the apparent temperatures of operational equipment, using the heat values to detect and avoid equipment loss. |
|
 |
|
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. |

A sensible approach to a steam system management program is to establish repair priorities based on safety, steam/energy loss, and possible impact on production and quality loss. |

Using a handheld thermal imager, you can capture infrared temperature measurements of a motor's temperature profile as a two dimensional image. |

Thermal images of electrical systems can indicate the operating condition of the equipment in those systems. |

This document outlines steps that will help you grow your thermography program into a key part of the way your company does business. |

The following discussion focuses on using thermal or infrared (IR) imaging to check for moisture in the envelopes of industrial, commercial and institutional buildings, including moisture in roofs, walls and insulation. |

In most cases, if only because of their high operating temperatures and their capacity to cause injury or death as a result of some failures, furnaces and boilers should be included in predictive maintenance (PdM) programs that monitor their condition while they operate. |

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. |

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. |

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. |

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. |

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. |

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. |

Normally, people in industry use level indicators to tell how much product is inside a tank. So why do so many of them also use thermal imagers (infrared cameras) to do the same thing? It's because of the horror stories. |

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. |

Electrical contractors typically use thermal imagers for predictive maintenance and troubleshooting, and sometimes during installation. |
