With the use of thermal imaging analysis on electrical systems it is possible to identify anomalies invisible to visual inspection such as electrical overload, imbalances, clamping defects on terminal boxes, and oxidation.
Thermographic techniques permit corrective and predictive maintenance, by distance assessment and measurement of heat produced by the electrical component being observed.
Thermographic analysis is a powerful tool in evaluating the health of an electrical system; such evaluation, as described in regulation UNI EN 9712, must be performed when the system is under full load. The distance at which it is performed always guarantees the safety of the assessing expert as well as without interrupting the operation of the system.
Such measurement has the objective of locating risk factors caused by overheating in components, which may require correctional intervention or repeated measurements in the future.
