Recommended Practice for Electrical Equipment Maintenance

In NFPA 70B under Section 2. Regularly scheduled inspection, testing, and servicing of equipment, you will see:

11.17.5 Inspection Frequency and Procedures:

Routine infrared inspections of energized electrical systems should be performed annually prior to shut down.

More frequent infrared inspections, for example, quarterly or semiannually, should be performed where warranted by loss experience, installation of new electrical equipment, or changes in environmental, operational, or load conditions.

FACILITY CONDITION ASSESSMENT

Industrial facility's often have very complex electrical systems and equipment. Much of this equipment was installed many years or even decades ago and therefore may have deteriorate into an unsafe condition. All too often equipment covers are left off or are not properly fastened in place, there are unused openings that have not been effectively closed, and listing and labeling requirements are not adhered to.
Regularly scheduled electrical safety inspections can assist in identifying these deficiencies, as well as other electrical safety issues that may put personnel at risk from electrical hazards.

PREDICTIVE MAINTENANCE PLANS

Predictive maintenance is a technique that uses data analysis tools and techniques to detect anomalies in your operation and possible defects in equipment and processes so you can fix them before they result in failure.
Ideally, predictive maintenance allows the maintenance frequency to be as low as possible to prevent unplanned reactive maintenance, without incurring costs associated with doing too much preventive maintenance.

INFRARED CAMERAS AND ELECTRICAL CONNECTIONS

Electrical wiring involves many discrete physical connections between cables and various connectors, and between connectors and mounting studs on equipment. The hallmark of a high-quality electrical connection is very low electrical resistance between the items joined by the connection. Continued electrical efficiency depends on this low contact resistance.

Passing a current through an electrical resistor of any sort dissipates some of the electrical power. The dissipated power manifests itself as heat. If the quality of the connection degrades, it becomes, in effect, an energy dissipating device as its electrical resistance increases. With increased resistance, the connector or joint exhibits a phenomenon called ohmic heating. Electricians and maintenance technicians use the thermographic camera to locate these hot spots in electrical panels and wiring. The heated electrical components appear as bright spots on a thermogram of the electrical panel
