Voltage withstand test can be divided into AC and DC voltage withstand test. AC voltage withstand test can be classified into power frequency, variable frequency and 0.1 Hz ultra-low frequency . Portable DC high voltage generator is used for AC voltage withstand test of rubber plastic cables up to 35KV and for insulation voltage withstand test of ends of small and medium generators.
