Embodiment Construction

[0007]figure 1 A system for inspecting electrical equipment 10 is shown in andfigure 2A method of inspecting electrical equipment 10 is provided in. The system allows the electrical equipment 10 to be inspected when the equipment 10 is powered (32) to monitor the effective performance of the equipment 10. The system may use a thermal imaging sensor 12 (34) that images electrical components 10a, 10b, 10c in the device 10. The device 10 can be enclosed in an electrical cabinet 14, and the sensor 12 can be inserted into the cabinet 14 through a port 16. The image provides temperature data of the components 10a, 10b, and 10c in the image. The system compares the temperature data of the parts 10a, 10b, 10c in the image (36) and generates a warning (38) when the temperature change exceeds a threshold value.

[0008]Such asfigure 1 As shown, the electrical components 10a, 10b, 10c may be enclosed in an electrical cabinet 14. A port 16 may be provided for inserting the thermal imaging sensor 1...

Abstract

A thermographic inspection system is provided for inspecting electrical equipment. The system may be used while the electrical equipment is energized to monitor active performance of the equipment. The system may be used to monitor temperature differences of various components in the equipment.

Description

Background technique[0001]The present invention relates generally to the inspection of electrical equipment, and more specifically to the use of thermal imaging inspection of electrical equipment.[0002]Electrical equipment is subject to wear and degradation over time, and it is preferable to check before the actual failure of the equipment. In many cases, due to safety considerations, inspections of electrical equipment occur when the equipment is out of service. However, this type of inspection can only provide limited information about the condition of electrical equipment. Examples of this type of electrical equipment that can be inspected regularly are switchgear or control equipment. Certain electrical equipment is also housed in a closed cabinet, which makes inspections more challenging.Summary of the invention[0003]A thermal image inspection device for inspecting electrical equipment when the electrical equipment is energized is described. The inspection system makes it possi...
