Atmospheric pollution measurements and their relevance to the flashover performance of overhead line insulators (TM-ETR-48)

A report has recently been written (Ref. 1) on the performance of porcelain insulators on the BR 25 kV electrified system. This has been prompted by recent reports of increased numbers of flashovers on the Weaver-Glasgow section of LMR/ScR during the winter of 1973/74 (see Fig. 1). The increased numbers...
