Desempeño eléctrico de aisladores cerámicos y poliméricos ante el crecimiento de microorganismos en su superficie : caso de estudio

Abstract

The present work of degree develops a case study whose objective is to determine the effects produced in the electrical performance of insulators due to the development of microorganisms on its surface. First, a controlled environment is designed to expose ANSI DS-15 type polymeric isolators and ANSI 52-1 and ANSI 55-2 type ceramic insulators to the development and growth of microorganisms Aspergillus Niger, Phanerochaete Chrysosporium and Chlorella Vulgaris. Additionally, from standard laboratory tests, the electrical and physical reference characteristics for new insulators are determined. Subsequently, standardized electrical tests are carried out on the biologically contaminated insulators and a comparison is made with the results obtained from the reference tests. Once this process is completed, an analysis of the results obtained and the conclusions of the work are presented. The development of this degree work allows an approach to the effects that could be observed in a natural environment and objectively establishes the effects that the biological growth of microorganisms can have on ceramic and polymeric electrical insulators. This aspect may be of great interest to the different actors involved in the electricity sector (generation, transmission, distribution, use).
