The temperature is a key variable in virtually any situation and for all process. Temperature is simply crucial and having control over it will mean higher quality. Better safety andmoney saved.

An infrared imaging device contains one or more detectorsthat converts energy in the infrared spectrum in to anelectrical signal. The more energy detected, the greater theelectrical signal output. The electrical signals are typicallyformatted in to video signal. If two objects are at sametemperature, the object with higher emissivity radiates more than object with low emissivity. Hence the first object looksbrighter than the second.

1) Electrical2) Mechanical friction3) Furnace & Boilers4) Quality control and process monitoring5) Fluid Flow problems6) Tank and Vessels.

Electrical Applications:Abnormal heat in electrical equipments is often the result of loose connections and over loaded circuits. The thermography can locate these problems before costly failure occurs,corrective action can be planned – which avoids shutdowns or costly down time.

The power generation, Transmission & Distribution problemsmanifest themselves as overheating when they resistant tocurrent flow increases as a result of poor connection.

Hence thremography allows diagnosing temperature relatedequipment problems developing trending data to predictequipment failure and determine equipment and plantpriorities and enhance operational safety.

Approximately 25% of electrical equipment failures are caused by faulty electrical connections, whether they are loose, dirty, corroded or over-tightening. The faults are not found during regular maintenance because one can not see the problemsuntil real damage to the component which may create faultor fire or emergency outage.

Advantage of Thermography:1) Improve quality of power supply2) Increase productivity3) Reduce Energy, Maintenance const & Scrap Materials Cost.4) Eliminate Down Time5) Schedule Maintenance Program improve Plant Safety &

Save Money.6) Early Fault Diagnosis Prevent Unscheduled & Costly

Production Stoppage.7) Analysis of results enables failure trends to be predicted.

In Generator / Alternators heated up observed due to :1) Phase Imbalance2) Dust / Carbon Accumulation on Slip ring Brush3) Improper tension of slip rings4) Poor Cooling of commutator / Armature5) Thyristor Bank failure

In Short, Thermography help to reach up to the targetwithout compromise the quality and Provide sufficient timefor preventive action.
