27.3 Oxidized socket
General
Depending on the type of socket and the environment in which the socket is installed,
oxides may occur on the socket's contact surfaces. These oxides can lead to locally
increased resistance when the socket is loaded, which can be seen in an infrared
image as local temperature increase.
NOTE
A socket’s construction may differ dramatically from one manufacturer to another.
For this reason, different faults in a socket can lead to the same typical appearance
in an infrared image.
Local temperature increase can also result from improper contact between a wire
and socket, or from difference in load.
Figure
The image below shows a series of fuses where one fuse has a raised temperature
on the contact surfaces against the fuse holder. Because of the fuse holder’s blank
metal, the temperature increase is not visible there, while it is visible on the fuse’s
ceramic material.
