INTRODUCTION

The ultra-low frequency dielectric withstand voltage test is actually an alternative to the power frequency withstand voltage test. It can replace large-capacity resonant transformers when conducting power frequency withstand voltage tests on large generators, cables, etc. The ultra-low frequency high-voltage generator combines the advanced technology of modern digital frequency conversion, adopts microcomputer control, and fully automates boosting, bucking, measurement and protection. Due to the full electronics, it is small in size and light in weight, and has a large capacitive touch screen LCD display, which is clear and intuitive, and can display output waveforms and print test reports. It is very convenient to use.

It has been proved from many years of theory and practice at home and abroad that replacing the power frequency withstand voltage test with the 0.1Hz ultra-low frequency withstand voltage test can not only have the same equivalence, but also greatly reduce the size and weight of the equipment. It is about one-fifth of the power frequency, and the operation is simple. Compared with the power frequency test, it has more advantages. This is why this approach is commonly used in developed countries.

After more than ten years of continuous research and development, the production technology of ultra-low frequency high-voltage generators has become more lightweight and intelligent; it has been upgraded from the previous series output maximum voltage of 80KV to single-stage direct output of 0-90KV.
