Infrared inspection and reporting process
An infrared inspection and reporting process and system obtains inspection data on site via a portable computer. An actual temperature of a component derived from an infrared image and a temperature delta between the temperature of the component and the maximum temperature for the component is calculated to determine if there is a problem. A criticality level is assigned for each problem component from a plurality of criticality levels each having a predetermined range for the temperature delta. The criticality level provides an accurate and consistent assessment of component conditions. The inspection data is up linked to a home server from the portable computer and is made available to the customer via an interactive, on-line web application. The customer can interact with the inspection dating including an interactive prediction of energy savings if the problem component is repaired.
1. A method of reporting an infrared inspection comprising the steps of:
obtaining a temperature of a component derived from an infrared image;
computing the maximum desired temperature for the component;
wherein the step of computing the maximum desired temperature for the component includes calculating the maximum desired temperature (T MAX ) using the formula T MAX =(Load 2 *Rated Rise)+T Ambient ;
wherein the Load is the electrical load on the component, the Rated Rise is the rated rise specified for the component, and the T Ambient is the ambient temperature surrounding the component;
computing a temperature delta between the temperature of the component and a maximum desired temperature for the component; and
assigning a criticality level for the component based on the temperature delta from a plurality of criticality levels each having a predetermined range for the temperature delta.
2. The method of reporting an infrared inspection according to claim 1 , further comprising the step of computing the Load using the formula Load=(Amps Measured /Amps Rated ) 2 , wherein the Amps Measured is measured from the component and the Amps Rated is specified for the component.
3. The method of reporting an infrared inspection according to claim 1 , further comprising the step of obtaining the Rated Rise from a database of manufacturer's information for a plurality of types of equipment.
