For example, heating and cooling of these
parts take place at different rates depend-
ing on the material and the time of day. For
this reason, it is important that other meth-
ods are used as well to check for moisture
or water damage.
Example image
The image shows extensive water damage
on an external wall where the water has
penetrated the outer facing because of an
incorrectly installed window ledge.
Faulty contacts in electrical
sockets
General information on faulty contacts
in sockets
Depending on the type of connections a
socket has, an improperly connected wire
can result in a local temperature increase.
This temperature increase is caused by the
reduced contact area between the connec-
tion point of the incoming wire and the
socket, and can result in an electrical fire.
To keep in mind
A socket's construction can differ dramati-
cally from one manufacturer to another.
For this reason, different faults in a socket
can result in the same typical appearance
in an infrared image.
A local temperature increase can also result
from improper contact between a wire and
a socket, or from a difference in load.
Example image
The image shows a connection of a cable
to a socket where improper contact in the
connection has resulted in local tempera-
ture increase.
Oxidized electrical sockets
General information on oxidized
sockets
Depending on the type of socket and the
environment in which the socket is in-
stalled, oxides may form 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 a local temperature in-
crease.
To keep in mind
A socket's construction can differ dramati-
cally from one manufacturer to another.
For this reason, different faults in a socket
can result in the same typical appearance
in an infrared image.
A local temperature increase can also result
from improper contact between a wire and
the socket, or from a difference in load.
Example image
The image shows a series of fuses where
one fuse has a raised temperature of the
surfaces in contact with the fuse holder.
The temperature increase is not visible on
the fuse holder because of its reflective
metal surface, but it is shown by the fuse's
ceramic material.
