Like other predictive techniques, thermography inspection allows identifying specific failures related to an inspection point. Generally, these failures are of direct evidence, however, it is also possible that it requires an analysis of the inspector correlating the reading of a parameter with some abnormal condition found.
Thermography inspection for predictive maintenance can diagnose the following failures:
High temperature
Hotspot
Uneven temperature
Thermal insulation issues
Deficient cooling
Gas or steam leaks
Blockage
Inadequate lubrication
Bearing wear
Shaft misalignment
Coupling wear
Rub
Pulley issues
Faulty connection
Damaged electrical insulation
High electrical resistance
Short circuit
Open circuit
Arcing
Corona discharge
Inductive current
Deficient grounding
