  • Aspects Of Insulation Resistance Testing | POWERTECH

    Oct 09, 2020Insulation testing is a very critical test to check the quality of insulation and prevent unwanted breakdowns. Insulation starts to age as soon as it’s created. As it ages, its insulating strength diminishes. Any harsh installation environment, especially with extreme temperature and/or chemical contamination, accelerates the aging process. This deterioration can result in dangerous
