Used to identify and document thermal problems in both electrical and mechanical systems. Abnormal heating in electrical systems is generally the result of loose or deteriorated connections, shorts, excessive loading, load imbalance or improperly installed components. In mechanical systems abnormal heating usually results from friction due to improper lubrication, misalignment or worn machine components.
Problems are identified using a thermographic camera which detects infrared energy emitted from a machine or component and produces a “thermal map”. The Thermographer then uses the temperature difference between the component in question and a reference (usually ambient, a similar component operating under similar conditions or the maximum allowable temperature) to determine the severity of the problem.
