INFRA RED / THERMOGRAPHIC  INSPECTION

Thermal imaging inspections provides us with a picture of the physical
unable to  detect. Thermal  imaging inspections  can locate defective
connections or components in time to prevent them failing. A
temperature increase indicates areas, which Inspections are a useful
tool in  preventive & predictive maintenance applications.
 
The value gained by our clients is that by identifying such problems
early (prior  to failure),  allows  remedial action  to be taken  that  will  
ensure safety, system integrity  and minimize the risk of expensive
repairs and equipment downtime. For example Infrared Inspection
Surveys should be conducted before the end of the warranties expire
on mechanical & electrical  equipment  and  machinery.  Ward  
Leonard  infrared  test inspections  can  also be  used to  monitor and  
document pre  and  post machinery  repair  work. Thermal  imaging  
Infrared  surveys  are  both noninvasive & nondestructive. Using the
latest infrared technology and diagnostic  equipment  our  
thermographers  scan,  test  and  diagnose system problems  and the
condition of equipment.
Ward Leonard Thermal Imaging inspections  provide a premium
service utilizing the highest levels of quality controlled inspection
procedures, accurate data collection, and the provision of a
comprehensive detailed report to facility managers and owners.

All electrical systems, equipment and components will deteriorate once  
commissioned. This  deterioration  comes in  many forms,  for example,  loose  
or corroded  connections  and  joints,  insulation All electrical systems,
equipment and components will deteriorate example,  loose  or corroded  
connections  and  joints,  insulation All subsequent  rise  in  temperature.  If  
uncorrected   this  rise  in connections  result in a high resistance  across the
connection with a temperature  will   continue  to  increase,  overheating   will   
occur, leading  to  life  shortening  of  the  system  through  equipment and
leading  to  life  shortening  of  the  system  through  equipment and
component  failure.  In the most extreme circumstances system or equipment  
failure  can  result  in  fire  and  possible  explosion.  Excessive loading of
electrical systems and equipment or phase imbalance of electrical systems
may also lead to failure. Deterioration and loading of electrical systems and is
not always apparent or detected by conventional routine  maintenance or
periodic test and inspection.
All mechanical equipment and components are subject to
deterioration once commissioned. This deterioration may be in
many under or  over lubrication. This deterioration will often
result in friction and  higher  than  normal  operating  
temperatures  which  if  left uncorrected  will  lead  to  
equipment  and  component  failure.  The environmental  
conditions  of  such  mechanical  equipment  and components  
must  also be taken  into  consideration.  Plant is often
operating outside and is therefore subject to extremes of
weather which may result in additional corrosion and wear.
Internal equipment may also be subject to harsh operating
conditions such as chemicals and abrasives (and other
aggressive materials).This deterioration of detected by  
conventional  checks such  as routine  monitoring  and
maintenance or vibration and oil analysis.
When equipment is in service and under load, existing faults and potential faults can become clearly visible with the aid of thermal imaging techniques.
In many cases this allows for instant fault diagnosis which in serious cases can be brought to the client’s attention immediately, allowing the necessary
remedial action to take place at an early stage. Minimising damage repair costs and system down time.
