Efecto Corona
Corona Effect

Corona is a phenomenon which results from air ionization due to high electrical fields. The detection of the corona effect is a technique which makes it possible to see each point of an object from a distance, either under a dynamic or stative condition, and at the same time, get a view of its discharges. Corona detection cameras can spot and produce images of light waves generated by the corona. In this way, visibility helps the engineer to apply the suitable means to solve the problem.

The use of the helicopter to monitor transmission lines allows to detect the insipient corona effect. Proximity together with low flight speed, favors such detection since it is quadratic dependent upon the distance at which it is observed. Considering it is not necessary to employ gyrostabilized platforms, flights are stationary at each tower, which results in excellent quality images.
