The problem of outdoor i
27、nsulator flashover due to contamination has existed as long as outdoor insulation itself. Insulator flashovers result in power outages that are expensive and hence undesirable. It was under- stood that in order to prevent flashover, the leakage current must be minimized. Room temperature vulcan (RTV
28、) coatings minimize leakage current by preventing water filming on the insulator surface. The use of RTV coatings began on a trial basis since the 1970s. Large-scale application of the coatings began in the 1980s. User experience of RTV coatings has been highly successful. But it must be mentioned t
29、hat for any specific application, judgment and experience are required to analyze and balance the many characteristics, which are discussed to obtain satisfactory performance and reliability. The work toward this guide began in the early 1990s. Round robin tests were performed in several laborato- r
30、ies. Concurrently, input regarding user experience was solicited. IEEE Std 957TM-1995a deals with some aspects of RTV coatings. This guide aspires to provide more details and information on the subject of RTV coatings. Participants At the time this guide was completed, the Outdoor Service Environmen

42、s 1. Overview 1.1 Scope This guide is based on the knowledge and experience of manufacturers, users, and researchers of room tem- perature vulcanizing (RTV) silicone rubber coatings that are used to improve the contamination performance of outdoor high-voltage (HV) insulators. This guide discusses v
43、arious important aspects that are needed for satisfactory long-term performance of high-voltage insulator coatings (HVIC)namely, various possible application scenarios, maintenance issues on coated insulators, factors affecting long-term performance, the question of aging, laboratory accelerated tes
44、ts, and functional outdoor evaluation. However, it must be men- tioned that for any specific application, judgment, and experience are required to analyze and balance the many characteristics, which are discussed to obtain satisfactory performance and reliability. 1.2 Purpose This guide is intended
45、for the use of RTV coatings on ceramic and glass insulators. 1.3 Applications This guide is specific enough to be applicable to porcelain and glass insulators in stations as well as trans- mission and distribution lines. RTV coatings are also in use for mitigating animal-induced outages in stations.
46、 The coatings used, and the important aspects, may be different than those used for insulator contamination performance improvement. The manufacturer should be consulted prior to use of HV insulator coatings for animal protection. Copyright The Institute of Electrical and Electronics Engineers, Inc.
