Abstract :
This paper discusses the current practice for selecting high voltage insulators and the changes needed to accommodate Load Resistance Factor Design. Conversion of insulator rated strength, defined according to ANSI C29 Standards, to damage limit strength to provide the service limit resistance required by LRFD is discussed. Specific values of service limit resistance and strength factors for different types of high voltage insulators are presented for further consideration by those responsible for revising current line loading and strength regulations and insulator standards.
