“if It Is not Broken, Do not Repair It” Thermal Imaging Electrical Systems

tags This attitude is all also typically applied to developing and machine electrical systems. With electricity seemingly often prepared for use, it is challenging to convince creating owners and facilities upkeep personal alike of the significance of extending their preventative maintenance applications to consist of electrical systems. And, with the use of thermal imaging cameras, it is simple to do.

My expertise as a journeyman electrician has provided me the chance to troubleshoot and repair numerous situations exactly where the use of a thermal imaging camera would have confirmed a useful tool and undoubtedly would have saved numerous lost production hours and expensive repair bills. Three such instances come to thoughts.

The first of the 3 situations involved a bakery in Tualatin. The bakery decided to add a second automated oven line identical to the very first. The original oven had had been in location about six years. The project went by means of the appropriate assessment processes and it was determined the existing electrical bus duct system would help the added electrical load. The second oven line had been in operation for roughly a year when the bus technique failed causing the shutdown of each oven lines and a freezer space. The emergency repairs needed working all day and through the night to limit the loss of production as nicely as loss of product. Evaluation of the broken bus elements revealed a connection point of the copper bus bars over heated and melted due to the not getting torque properly throughout installation. Even though the buss program had been in operation for over six years ahead of the new oven line was installed, the further load is what stressed the poor connection to the point of failure. Of course hind sight tells me that thermal imaging of the buss connection points ahead of and/or soon after the installation would have exposed the issue location. The reality is that periodic upkeep imaging would have prevented the issue from ever becoming a expensive problem.

The second event took place at an industrial complex in Beaverton. The constructing, owned by a property management group, houses two separate organizations, 1 involved in label printing and the second a Japanese meals processes facility. The printing firm installed a new industrial printing machine that sooner or later brought on a meltdown of a fuse clip in the principal building panel feeding the person leased space distribution panels inside the month. The meltdown was determined to be a wire connection becoming loose from expansion and contraction over time. The new machine’s load pushed the bad connection beyond its capability to manage the added existing. A temporary repair was place in location soon after the initial failure but the equipment required to be replaced and as typically takes place with older equipment, repair components were not offered so new equipment had to be installed. Despite the fact that a weekend shut down was planned to set up the new equipment, the food processing facility had to cancel weekend shifts and suffered loss of
some product due to refrigerators being powered down. Once more, periodic thermal imaging would have exposed the vulnerabilities of the electrical technique prior to installation of new equipment and would have paid for itself many occasions over in money saved on repair expenses and lost revenues.

The final example involved a main video distribution warehouse in Wilsonville. The warehouse was illuminated with higher bay metal halide (HID) lamps typical of a lot of other warehouses and the complaint was erratic lighting issues all through. Investigation into the issue exposed the neutral wire in the lighting breaker panels had been broken by heating caused by non linier load problems (non linier loads are a topic of an additional discussion). I a single case, the neutral wire was entirely burned and became disconnected from the terminal. This dilemma most definitely would have been exposed with a scheduled thermal imaging maintenance system.

“An ounce of prevention is worth a pound of remedy” is yet another wonderful quote that applies to this topic due to the fact there by no means appears to be a great time to shut down your facility to repair a broken electrical system that could have been avoided with that ounce of preventive upkeep.

Some of the insurance business offers you a discount if you have thermal imaging completed giving you a far more of a reason to do this.
