VLF-34E 34 kV VLF Tester
Very Low Frequency AC Technology
VLF&DCOutput•SheathTesting•CableBurning
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.
