This causes noise at the fault position which can be detected either by sight &#8211; a high voltage surge can generate sparks, by feeling with a rubber glove, or even by hearing.<\/p>\n<p>This method, however, is not fool-proof. So when, at a trade show, Andreas Becker saw how quickly and accurately thermal imaging can display voltage changes as heat differences he decided to invest in a FLIR camera to complement traditional methods.<\/p>\n<p>The model he chose is a <span class=\"highlight highlight-blue\"><a href=\"http:\/\/www.flir.com\" target=\"_blank\" rel=\"noopener\">FLIR E40bx troubleshooting camera<\/a><\/span> because it is easy to use, straight out of the box. It provides a temperature measurement range of -20\u00b0C to +120\u00b0C with an accuracy of \u00b12%.<\/p>\n<p>Other features that proved decisive in the purchase was MSX thermal image enhancement that allows numbers, labels and other key visual details to be seen in an all-in-one thermal picture.<\/p>\n<p>Also important to Becker and H\u00fcser is the camera\u2019s ability to be linked via Wi-Fi to a mobile device or smart phone. This allows engineers to transfer images, add further measurement spots, re-adjust level and span, change palettes, create reports and email findings to decision makers or customers.<\/p>\n<p>\u201cWhen all our traditional methods of fault detection fail, we know that we can still use our FLIR camera to locate the problem\u201d Andreas Becker continued. \u201cIt is particularly effective on faults at the end of the cable, right at the point of connection, that are difficult to detect by other means. The camera can see the heat difference without any problem. And it\u2019s also ideal for inspecting the entire length of a cable as it is wound from reel to reel.\u201d<\/p>\n<p>He concluded \u201cIt is an enormous advantage to be able to show the location and nature of the fault and the FLIR camera allows us to do just that. It gives our customers confidence that we are on top of the problem.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Heavy industries such as mining, shipbuilding and materials handling rely on heavy, rugged, industrial cables to ensure continuous power supply or communication.
