摘要：
High electric field strength may cause problems, such as corona and deterioration, on nonceramic insulators. Therefore, control of the electric field strength (E) in the vicinity of such insulators is an important aspect for their design. This paper discusses insulator computation models and their applications to 34.5 kV and 765 kV nonceramic insulators. Possible model simplifications are reviewed and discussed. Various 765 kV insulator designs and tower types are covered; the magnitude and distribution of E are reviewed. Verification tests are also described.
