OK clearances spanned insulation type (functional insulation, basic insulation, additional insulation, reinforced insulation). Creepage distance steps:?? To determine RMS or dc operating voltage; determining a material group (based on comparative tracking index, which is divided into: Ⅰ group of materials, Ⅱ group of materials, Ⅲa group of materials, Ⅲb group of materials .?) to determine the level of contamination; determining the type of insulation (functional insulation, basic insulation, additional insulation, reinforced insulation)
