Abstract :
In electrical tests on insulating materials for transformers, general, in-model test arrangements varying the parameters of electrical properties are established. These values cannot be transferred to real transformer insulation without further consideration. However, from these individual test results with their differing statistical variations of parameters of electrical proportions, statements about the electrical strength of the insulation are drawn and evaluated.<>
