In instrument practice the step voltage test relies on sound insulation behaving resistively, so that raising the test voltage raises the current in proportion and the computed resistance stays constant. A resistance that falls as the voltage steps up indicates ionization at pinholes or cracks in the insulating material, which is what the test is used to locate.
