Can anyone explain how to interpret a megger test result on a cable?
SITUATION: Chiller upgrade, power cables (480V, 3 phase)were scraped on sharp edge of bushing during pull. Contractor says only the pulling jacket was effected, not the insulation. Megger test was performed and all resistance tests "were in excess of 100 Megohms". What exactly does this mean? Does this mean, definitively, that the insulation has not been damaged?
thank you in advance for your response.
