What is an expected outcome if an insulation step voltage test reveals cracks?

When an insulation step voltage test reveals cracks, it indicates a significant issue with the integrity of the insulation material. The presence of cracks suggests that the insulation is no longer able to adequately perform its primary function of isolating electrical components or systems. This reduced effectiveness can lead to potential electrical leakages, short circuits, or even catastrophic failures in electrical systems.

In this context, the outcome pointing to the need for replacement is appropriate. Cracked insulation cannot simply be relied upon to continue providing safe and reliable operation; it poses a safety risk and could result in further damage if not addressed. Therefore, it is crucial to consider replacement to enhance safety and ensure continued functioning of the electrical system.
