12.1 Moisture & water damage

It is often possible to detect moisture and water damage in a house by using an infrared

camera. This is partly because the damaged area has a different heat conduction prop-

erty and partly because it has a different thermal capacity to store heat than the sur-

rounding material.

NOTE

Many factors can come into play as to how moisture or water damage will appear in an infrared image.

For example, heating and cooling of these parts takes place at different rates depending on the material

and the time of day. For this reason, it is important that other methods are used as well to check for

moisture or water damage.

The image below shows extensive water damage on an external wall where the water

has penetrated the outer facing because of an incorrectly installed window ledge.

12.2.1 General

Depending on the type of connection a socket has, an improperly connected wire can re-

sult in local temperature increase. This temperature increase is caused by the reduced

contact area between the connection point of the incoming wire and the socket , and can

result in an electrical fire.

NOTE

A socket's construction may differ dramatically from one manufacturer to another. For this reason, differ-

ent 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 wire and socket, or from dif-

ference in load.

12.2.2 Figure

The image below shows a connection of a cable to a socket where improper contact in

the connection has resulted in local temperature increase.
