Preventing Flashover: A sufficient creepage distance ensures that, even in the event of environmental contamination or moisture buildup, the transformer insulation can withstand the voltage without allowing electrical discharge to occur along the surface.
Improving Insulation Longevity: By ensuring that the creepage distance is adequate, transformers are protected from surface tracking, which can degrade insulation over time and eventually lead to failure.
Enhancing Safety: Proper creepage distances ensure that, in the case of an electrical fault, there is a lower risk of arcing or electric shock, which can cause harm to personnel or damage to surrounding equipment.
