The use of thermal imaging cameras has revolutionized predictive maintenance inspections for various electrical components and equipment. It can provide substantial cost savings by identifying potential electrical problems before failure thereby avoiding unscheduled downtime. As electrical equipment ages, component fatigue due to heating, increased conductor resistance, loose connections and overloading can cause equipment failures. Infrared (IR) Thermography detects thermal patterns and associated temperatures of components to identify potential issues. Once these hot spots are identified, customers can isolate energy sources to inspect and repair equipment before a failure.
