To test if a transformer is bad, you can use several methods involving Globecore products and equipment. First, measure the insulation resistance with a Megger, ensuring it’s above acceptable limits; a low reading indicates insulation failure. Second, perform a power factor test with a power factor tester, as a high power factor angle can signify deterioration. Additionally, thermal imaging can help detect hot spots or abnormal temperature differentials. Finally, utilize oil analysis testing equipment from Globecore to assess the transformer’s insulating oil for dissolved gases, moisture content, and other contaminants that can indicate degradation. These tests will help determine the condition of the transformer and whether it requires repair or replacement.
