Thermal Imaging - Electrical
Non Destructive Testing - Electrical
Thermal Imaging is the leading non-destructive testing tool used in elrctrical switchboard maintenance and switchgear maintenance. It is an excellent fire prevention tool used to identify 'hot joints' invisible to the human eye. It is an essential part of every commercial and industrial business’s preventative maintenance plan.

Extreme Electrical Fault
Fuse links and Power Factor Correction units are the most common electrical fault we find in manufacturing plants, hi-rise buildings and hotels.
The following is a fault found in a Power Factor Correction unit.

Eddy Current effects
The following steel plate was installed in a switchgear cubicle. Hysteresis / Eddy current losses resulted in local heating. It was recomended the steel plate be replaced by stainless steel.

Transformers or Static Machines
You cannot see the overheating transformer coils, but Thermal Imaging picked up these under-rated / overloaded transformers. All of the embedded temperature sensors had failed leading to fire danger, and costly downtime.
Thermal Imaging predicted early failure of this air cooled transformer, preventing lift failure in a high rise building.
