Plan the installation of the windows starting with the highest priority, taking into account electrical equipment availability shutdown schedules , frequency of inspections and hazards. When purchasing IR windows, consider bulk purchases.
In addition to possible discounts, having more windows available will prevent any delays during installation and possibly allow additional windows to be installed if an opportunity arises.
Because infrared window installations require modifying electrical enclosures, qualified electricians who understand proper window placement are often the best choice. When uncertain of correct window placement, electricians may opt to work with an experienced thermographer to help with window sighting. Be sure all targets are identified.
In addition to fuses and breakers, include cable and bus connections and any mechanically fastened connection. Placement of IR ID labels should be considered during installation to ensure repeatable data collection during IR inspections.
No one will deny the safety hazards involved when working with energized electrical equipment. The need to perform more comprehensive infrared inspections , while reducing safety risks, is facilitating the installation of infrared windows.
Inspections will no longer require multiple trained staff to open and close the panels. And after all… time is money! Data Management: IR windows provide a systematic approach to data collection during inspections — same target, same location, same angle, and same distance. Consistency in the data collection process leads to more trendable data in any PdM process. Risk Management: The Hierarchy of Control requires engineers and managers to eliminate risk where possible as opposed to relying on engineering controls or PPE to protect personnel after the accident happens.
Use of IR inspection windows eliminates the high risk behaviors involved with open panel inspections and replaces them with a non-intrusive work process. Safety: The possibility of performing an infrared survey of energized electrical equipment without removal of the panels reduces the risk of electrocution or an arc flash incident.
Standards Complaint: The equipment is maintained in an enclosed and guarded condition without creating a potential electrical hazard during inspection.
Ideally, increased safety and reduced risk of injury should be enough reason to install IR windows. However, some facilities will be required to show the Cost Savings. Not only do Fluke CLKT IR Windows deliver a clearer view of the equipment being inspected, the also present a larger viewing area than other windows on the marker. Since the entire area of the crystal optic is available for infrared transmission, it provides optimum repeatable results.
It also provides a better view for visible light inspections. That means the user can change the camera without having to change the IR Windows. Quadraband optics transmit electromagnetic radiation in:. The user also gets a strong support network to work with before , during, and after the sale. It takes just one person about 10 minutes to install a Fluke IR Window. This helps to minimize installation labor costs and system downtime. Just power down, remove the panel cover, position the window using the included template, drill the hole, and affix the window with three self-tapping screws.
Because all the mounting hardware attaches to the outside of the panel there are no parts insides that can work loose and cause of short. Do you simply want to take a digital photograph of a problem to help with a repair?
Make no mistake, by redirecting the arc energy, it is the engineering of the switchgear , not the window, that is making it possible for the switchgear to pass this test of an extremely violent explosion. Standard that is "non-Arc-Resistant" switchgear is not outfitted with systems that redirect the arc energy. Therefore, the blast forces impacting the doors and windows can be 10 to 20 times higher than they are on Arc Resistant switchgear -- in other words, windows on standard switchgear are not being hit with 30 PSI, but rather with to PSI or more!
The pressures and heat involved under similar conditions on standard switchgear would yield significantly different results. That is why Exiscan does not engineer its IR inspection windows to pass tests where the arc energy is mitigated and redirected. Frankly, it's not a very high bar. Exiscan TM engineers it's IR windows and other inspection windows to outlive the equipment to which it is attached.
By doing so, Exiscan TM inspection windows allow the switchgear operate the way it was designed -- either to redirect the blast for Arc Resistant equipment , or to fail the way it was designed to fail in the event of standard equipment. To understand how we can make our windows outlive your enclosure, you have to hold an Exiscan TM IR window:.
