Today, we will explain how to judge the insulation level of a transformer. This is because the insulation level is a standard for assessing transformer quality, and as a transformer manufacturer, we feel it’s necessary to explain this to facilitate detailed selection in the future. Before introducing the identification methods, we need to understand that the insulation level is generally evaluated by measuring a set of rated withstand voltages.
Below are our manufacturer’s testing methods for this area. We generally have three measurement methods:
