![]() ![]() The decision whether or not to remove is then usually taken only as preventative measure once heavy colonization has been identified. Fortunately, field experience has shown that in only few cases does mould growth require removal. In the case of composite insulators with hydrophobic surfaces, however, this valued performance-enhancing property can be temporarily diminished or even lost. Mould growth can therefore only increase thickness of the pollution layer. The effect on inert glass or porcelain surfaces is minor since these materials are already hydrophilic. In a service environment characterized by elevated humidity and temperature as well as presence of species of mould, surfaces of insulators – both ceramic and composite – can become colonized. Offer special insight into some aspect of power transmission and distribution. Provide unusually high technical or visual overview into the topic of interest and/orģ. Unique in the sense that they capture a special situation that cannot easily be replicated Ģ. Favorite photos were selected based on their meeting one or all of the following criteria:ġ. In this last of a 3-part series, the photos themselves are the primary focus. During these many site visits, we have taken tens of thousands of photos to support the resulting technical articles. For nearly 30 years, INMR has travelled the globe covering power line and substation projects on all continents and also been invited into factories for electrical equipment worldwide as well as into test laboratories and stations.
