VERY LOW FREQUENCY AC HIPOT

VLF Cable testing for cables rated to 35kV

VLF-6022CM(F)
Features and Benefits
The High Voltage, Inc. VLF-6022CM(F) with its 62 kVac peak output,
is suitable for all testing of 35 kV cable per IEEE 400.2-2013. Its high
load capacity enables it to test up to approximately 15 miles of cable (at
.02 Hz), depending on type. Introduced in 1997, the VLF-6022CM(F) is
our simple and reliable electromechanical unit. For advanced features
such as remote operation, programming, professional reports and solid
state menu driven technology see our E-Series VLF-65E.
