The very-low frequency insulation testing is actually an alternative method to the power frequency withstand voltage test. Using a 0.1Hz very-low frequency withstand voltage test not only has the same effectiveness but also significantly reduces the volume and weight of the equipment. The capacity theoretically is about one five hundredth of the power frequency and the operation is simple.
