VLF hipot and VLF testing is as simple as just an AC hipot on lower frequency output (at 0.1 Hz). The only way to field test high capacitance loads with AC voltage, like cables and motors/generators, is to use a VLF AC hipot. Lower the frequency, Lower will be the current and power needed to test high capacitive loads.
The reason it has not been widely used for more than 4-5 years is because only in the last 5 –10 years has it been determined that DC voltage testing damages solid dielectric cable and is an ineffective means of determining insulation quality.
The IEEE/EPRI/CEA and other world engineering bodies recommended VLF test level for solid dielectric cable is up to three times (3Vo) line to ground voltage for 15 + minutes. For example, A 15 kV cable system, with line to ground voltage up to 7.2kV, is to be performed at 22kV.
