Thermographic inspection

Infrared Thermography is ..

• a graphical representation of heat

• an accurate measurement of temperature

• a photographic representation of heat

A good thermogram contains qualitative and quantitative information.

• True

• False

What's the hottest element in this image?

• Cockpits

• Track

• Tires

• Wall

The meterial with high emissivity will be good infrared reflector.

• True

• False

Infrared wave can go through transparent object such as glass, plastic, etc..

• True

• False

What's the most likely explanation for excess heat in the fuse?

• High loading in this phase

• Internal damage in the fuse

• Reflect of a hot object

• Loose fuse clip

How can we classify the heating on this load break elbow

• This is a normal heat pattern

• There is a connection problem inside the elbow

• The heating pattern suggests a high load on this phase

• The temperature we measure on the surface is an accurate assessment of the internal temperature

In order to capture the smaller object size at the same distance, the larger IFOV thermal imager is preferred

• True

• False

If the emissivity of a material equals 0.10, what type of material would you most likely be looking at?

• Wood

• Plastic

• Shiny metal

• Painted metal

Which parameters can't be adjusted or compensate for during post processing

• emissivity and image contrast

• color palette and emissivity

• focus and temperature range

• image contrast and focus
