GARCIA QUINTERO, Edwin. Study of the damage on dry isolated materials through high voltage techniques (Partial Discharges). Ing. Desarro. [online]. 2010, n.27, pp.25-47. ISSN 0122-3461.

In this work the damage on low density polymeric isolated material is evaluated (Ethylene-Propylene) in a power wire of 12/20 kV, from the partial discharges technique (PDs) for three different types of objects: one without defect and other two with it (drilling with pointed object and connection). Additionally to this, a function of patterns is to set out and allow to quantify, visualize and to discriminate defects in the same isolation. This just with the purpose to obtain on the three test tubes, which of them show the most relevant defect and in consequence let us to know the total damage on the isolated system. As results, we find that connections are the most important damages followed by the defect due to the drilling on the isolation. In relation with the patterns function PDs, this one, make a good difference among defects highlighting in a graphic and qualitative way, the most relevant, and so, improvement some deficiencies showed by the functions of patterns that already exist.
