Abstract :
The author replies to comments by Danikas about the paper he co-authored with I. Ramirez-Vazquez and G. Montoya-Tena (see ibid., vol.143, no.6, p.560-4, 1996) regarding the recovery period for RTV-coatings. He points out that the results were obtained on standard- and flat-type porcelain insulators without any RTV-coating, However, several tests have been carried out using the same insulator profiles with RTV-coating. The results obtained were very similar to those for uncoated insulators in a continuous salt fog test (1000 h) following the procedure mentioned in IEC1109
