Solve Problems BEFORE They Start!

Occasional system and equipment failures are inevitable, so most businesses build contingency plans to bring production back on line as fast as possible. But while failures can never be entirely avoided, when it comes to preventing unexpected downtime and lost productivity, Infrared Thermal Imaging technology is an excellent defense.

Thermal Imaging detects variations in temperature of electrical components. In the case of electrical switchboards, a thermal imager can detect “Hot Spots” that are invisible to the naked eye. By displaying circuitry that is operating at an unsafe temperature, Thermal Imaging enables early detection of problem areas, avoiding danger, costly repairs and unscheduled downtime.

Any electrical distribution system, machinery or conveyor motor and control panel will benefit from annual Thermal Imaging. If a regular Electrical Planned Maintenance Program including physical inspection is in place, and the condition of the equipment is generally good, a bi-annual Thermal Scan may be sufficient. However, for older equipment and in harsh working conditions, annual and even semi-annual inspection may be recommended.

Thermal Scans identify hot spots – these are typically connections to electrical equipment that are not in optimum condition. This can indicate the need for replacement or simply cleaning and adjustment. Distribution switches or disconnects can also show hot spots which are often related to poor switch conductivity, fusing issues or other problems. Thermal Scans should be conducted by a qualified technician with the expertise to accurately interpret the results and recommend appropriate remediation. Purchasing Thermal Imaging equipment and attempting to diagnose electrical problems in-house without this expertise is not advisable and could be dangerous.

Implementing Thermal Imaging as part of your Electrical Planned Maintenance Program will help to maximize productivity. Scans should be performed on all production equipment, substations and electrical distribution equipment 30 to 60 days before regularly scheduled shutdowns. This will allow time to order any required parts and schedule repair work during the shutdown, rather than when your facility is up and running again. Once equipment is repaired, a follow up scan should be completed to confirm that all problems have been addressed.
