Atec VLF-34E User Manual

VLF-34E 34 kV VLF Tester

Very Low Frequency AC Technology

VLF & DC Output • Sheath Testing • Cable Burning

The VLF-34E is a new generation VLF AC hipot that uses a solid state

design with microprocessor controls. It meets the requirements of
applicable world standards regarding cable testing up to 25kV class
Maintenance testing. It is light, compact, rugged, and very portable.
Its sine wave output is suitable for using optional external PD and TD
detection equipment. Using a TD and PD option, the VLF-34E is all
that is needed for nearly all cable testing up to 25kV class.
