Principle of the ultra-low frequency insulation voltage test
The ultra-low frequency insulation withstand voltage test is in fact an alternative to the industrial frequency withstand voltage test. As we know, in the test of large generators, cables and other test products for industrial frequency withstand voltage test, because their insulation layer presents a large electrical capacity, so need a large capacity test transformer or resonant transformer. Such some huge equipment, not only bulky, costly, and very inconvenient to use. In order to solve this contradiction, the power sector has adopted a reduced test frequency, thus reducing the capacity of the test power supply. From the theoretical and practical proof of many years at home and abroad, with 0.1Hz ultra-low frequency withstand voltage test instead of frequency withstand voltage test, not only can have the same equivalence, and the volume of the equipment is greatly reduced, the weight is greatly reduced, theoretically the capacity of about one fifth of the frequency, and simple operation, compared with the frequency test superiority more. This is the reason why this method is commonly used in developed countries.XHDP-50M 50kV VLF AC Cable Hipot Tester
