Hot 2000KVA Transformer Bushing
Here is a case study showcasing how infrared scanning works. The visible light photo shows a typical configuration of a pad-mounted transformer's low voltage side showing no signs of a damage. The thermogram shows a problem area of higher temperature highlighted in red. The targets that appear are numbered from left to right. Note the higher temperature of the one located in the center.

Newly Installed Parts on a 2000KVA Transformer
|
This example is another problem commonly seen in a transformer. The visible light photo is of a pad-mounted transformers' high voltage side. It is critical to the transformer's operation that these wire connections remain tight. The thermal image is an infrared scan of the elbows. Note one segment is bright red, indicating dangerously high heat. Compare its color to the gauge at the right side of the photo.

Hot Spot in a Medium Voltage Distribution Box
|
This piece of equipment is called an Outdoor Medium Voltage Distribution Box. These cables are responsible for supplying the transformers seen above, and therefore a significant amount of electricity to the operation of a factory. The only way to prevent failure and ensure continuous operation is to verify their condition. The thermal image shows the result of an infrared scan, and demonstrates dangerously high heat in the leftmost cable coupling. Note the targeted temperature compared to the adjacent cables.

Critical Connection
The visible light photo shows the inside of a wiring junction box. The photo on the right shows an infrared scan revealing a loose connection in the box that is at a dangerously high temperature. The standards used for ranking such problems places this issue in the critical/repair immediately category. Compare the white-hot color to the gauge at the right of the photo.

300 Amp Wire Connections Don't get Better
This thermogram demonstrates one of the most dangerous and critical problems we have ever discovered. In an ideal situation, all three fuses and their corresponding wires should be close to the same temperature. The targets show the varying temperatures of each, especially the one in the center, which is rated in the critical/repair immediately category.
