HVI’s smallest VLF model, the VLF-30CM(F) approaches the size and cost of a DC hipot and is designed for quick and easy short-run cable testing.

It can test up to 0.4 mF of load, or up to 4000 feet (1200 m) of a typical 11 kV class cable.

Features and Benefits

The High Voltage, Inc. VLF-30CM is one of the smallest and lightest VLF ac hipots available. HVI introduced sine wave VLF technology in 1997. This model has been in field use since 2002 and has proven to be a very durable design. Economical and easy to use, it is perfect for withstand tests on shielded power cables per IEEE400.2-2013. The VLF-30CM is our basic unit, for advanced features such as remote operation, programming, professional reports, and solid state menu-driven technology see our VLF-34E.
