    4. IR Thermal Imaging Surveys – Infrared electrical inspection. Infrared electrical testing finds hot, dangerous problems quickly. Infrared electrical inspections find hot spots caused by defects in connections and components.

    Detect system overloads, loose defective components and damaged switchgear. Infrared electrical testing finds hot, dangerous problems quickly. Infrared electrical inspections find hot spots caused by defects in connections and components.

    Infrared thermography is used to find areas of excess heat (caused by increased resistance) so that problems can be corrected before a component fails, causing damage to the component, creating safety hazards and productivity loss. Because increased heating is a sign of failure, infrared is the best diagnostic tool available for finding these hot connections in the early stages of degeneration.
